Now the electrically operated bicycle more and more receives people’s favor, its good operation, the use convenience, safe receives people’s like, but in the market electric car’s brand is very numerous and diverse, electric restaurant car how should choose the electrically operated bicycle is the matter which everybody institute pays attention together.
1. chooses the well-known brand: The well-known product first leads in the fund strength, only then the fund strength is formidable, can hire the first-class research and development team, can purchase the high quality the material, such vehicle can have the safeguard in the quality and the performance. The famous brand goods its each kind of credential is complete, the production intelligence is also the process examines many times, has been is subject to the related quality monitoring department to pay attention, and undergoes the massive consumer’s actual confirmation, can set up the shape electric fire engine elephant in the wide range consumer’s mind, has the oral traditions. Therefore the brand is first should consider.
2. batteries: The electrically operated bicycle’s battery is very important, looks like automobile’s gasoline to be the same, the vehicle always refuels troublesome, always needs to charge is also very important, therefore chooses the capacity in a big way as far as possible in the choice time period of five days, compared to like 48V20Ah, the distance which may go like this is farther, avoids going to half distance not electricity, fire rescue trucks but also there is no place charge no use situation, also reduced battery’s charge number of times, lets the battery life be longer-term. The electrically operated bicycle’s battery price is also very expensive, trades a battery to occupy the overall price about 35%.
3. post-sale service: Must choose certainly has the consummation post-sale service brand, compared to like maintenance point many, post-sale service perfect, the electric car in uses in the process to have any question like this accidentally also to electric patrol fire engine car facilitate solves, lets our customer after the purchase may feel relieved the use, does not have the extra worries.
4. choices suit their number: The electrically operated bicycle’s vehicle type has many kinds, has the exquisite belt foot pedal, has the volume very in a big way, this acts according to own demand as well as drives the convenience to consider, if road sense common or not good woman, suggested that the purchase exquisite belt foot pedal, this kind of vehicle type’s moving velocity will not be very quick, the vehicle type will be advantageous for the control exquisitely, will meet the emergency case convenience to deal! But if is the gentleman purchases, choice number big, battery capacity big, such driving speed as well as the load-bearing quantity can meet the demand.
5. gauge marketing spot: Must certainly in the gauge’s sale point purchase, and demands the gauge
electric fire truck receipt and the maintenance card. This may guarantee that our legitimate rights and interests obtain the maintenance, guaranteed we purchase the product resourcess are well used, avoids deceiving by the bad business!
After most, reminds all pilots, although vehicle’s quality has guaranteed, but we in drives in the process to observe the junction certainly to pass the rule, do not because of temporary negligent or electric cargo truck impatient, but creates the being unable party’s ache for us and the family member!

Our country electrical energy assignment the influence which develops to the pure electric automobile
Our country’s electricity generation total quantity occupies the global first place, middle 25 plans, our country has each year 100,000,000,000 electricity generation total quantity nearly, this electric utility truck total quantity is quite astonishing, although the total quantity is huge, but as a result of the special national condition, our country electrical energy distribution is quite actually non-uniform, the west has place Fang Youdian there is no place causes, can waste only, but the east has the place side does not have the sufficient electrical energy supply date often to live and to produce, therefore created the electricity to be hurried, this fact’s existence let the pure electric automobile in our country’s development faced with not the small limit.
Very hears when the electricity hurried news the first impression is we everywhere lacks the electricity, therefore they will have such question, “, since the nation did not have the electricity to use, then why could also develop the pure electric automobile vigorously”, the reason that will ask this question its electric utility vehicle reality was because opposite party has not poured Italy to lack the electricity is only the local phenomena, in fact our country nation total electric quantity was quite plentiful, if could assign the nation evenly, then developed many pure electric automobiles not to need to worry used electricity question.
Although we said the total quantity to be sufficient, but assigns the uneven fact is the existence after all, now also did not have the concrete measure to solve this kind of unevenness, therefore the current pure electric automobile’s development is facing not electric utility car the small limit, only then matches with the electrical network electrical energy only then may be able to guarantee that the automobile is often using, if enters the large scale production to put in the market ahead of time, then by very many sides because of partial reason, but shape Cheng Dian the hurried present will become more serious, such can bring only to the society troublesome, but under this situation we cannot say that the pure electric automobile let the people feel has received the convenience.
The pure electric automobile’s development faces the limit, however these limit are relieving little, lack the electricity each provinces and cities positively to develop own power supply to originate, with when seeks help to other provinces, transports by the time other provinces extra’s electrical energy supplies this local use. We believe with the lapse of time, this kind of interprovincial between can the source hand over easily golf car with cargo box certainly to be more frequent, but faces for the pure electric automobile’s development the limit will be also getting fewer and fewer, therefore may develop smoothly
In the pure electric car develops in the middle of the process, will bump into very many kind of questions, but about the electrical energy supply’s question will be a matter of life and death, will have the electricity to live the electricity not to die. Any thing’s development must be suitable the environment actual situation to take the corresponding measure, the current our country’s environment is the electrical energy assignment is uneven, therefore the pure electric car “eats meal” is restricted, but golf cart once these limits have relieved, we might by the maximum speed development be able newly the source automobile.
Perhaps we now have make the pure electric automobile’s strength massively, but we must consider, the personnel shape situation, people receptivity aspects and so on technical maturity, judge the national electrical energy assignment most importantly the uniformity, like this can lead them on the best development track, electric semi truck pushes the pure electric automobile smoothly along the locality, lets the electric automobile automobile enter everyone.

The Chinese electric automobile development faces challenge
The electric car profession was still a young profession at present, is one lets the bicycle profession look forward to, lets the automobile profession side goal profession. Although the stamina is full, but also just is because young, therefore easier to expose some questions. However, we should not hide faults electric sightseeing car for fear of criticism, perhaps just is because these questions and the challenge only then let the electric car profession the prospects for development appear broader.
Strikes root in the hearts of the people gradually along with the world environmental protection idea, the electric car profession’s technology several passes through the twists and turns, the date hastens the consummation, electric automobile finally in 21st century Cheng Wei the junction passes the profession the eminent.
But China does for the whole world first big auto market, at present is welcoming the unprecedented
electric green car opportunity, is also facing the unprecedented challenge.
1st, the Chinese electric car profession’s development localization has treats is clear
The electric automobile present is bringing more boosts for the Chinese automobile profession, but rather has an urgency in the developing process. Supposes in the technical route decides found the emphasis point with difficulty, moreover because of market demand’s all sorts of strange and unusual, enables the technological development to have not to feel the brains unavoidably. Not only that the Chinese electric automobile whole’s development route is also the question which determined with difficulty. The electric automobile profession development until now, experienced the technology to absorb the independent development the process, is should follow the traditional automobile profession the development route, this wards off the path in addition, at present not yet has electric classic car an explicit judgment.
2nd, the electric automobile industrial production enters the bottleneck time
The electric automobile transports with the technology has the very big difference with the traditional automobile, and our country starts late in this aspect, therefore compares with the foreign country, the technological gap is not a tiny bit. In invests the high new industrial aspect, before also has not to hesitate. Because the electric car industrial production’s prospect is not very explicit, causes very many investors not to dare to ford rashly, most is only the attempt carries on the jot investment, the shape becomes the scale with difficulty.
3rd, necessary supposes prepares insufficiently completely
If the electric automobile profession wants to want the shape to become the scale, is facing a not allow to neglect question, is can the source supply. Looks like the 17 passengers shuttle car traditional automobile profession to have the gas station to proliferate the world, electric automobile’s charge supposed prepares present up to still did not have the mass placement. This causes originally should supplementary necessary to suppose with the electric automobile prepares, instead has become one vicious circle with the electric automobile shape: The electric automobile profession’s urgent development demand and necessary supposes prepares the construction amusement electric train slow present situation to become the restriction mutually.
4th, Cheng Bengao with marketability between contradiction
The electric automobile does is one kind of commodity, its market demand is closely linked on the necessity with the price. But because nowadays the technology, the material, can aspect and so on source finiteness cause the electric automobile to become this have unprecedented reduction with difficulty throughout. Although electric automobile’s green environmental protection very greedy, but present looks like is opposite in the price more inexpensive tradition automobile, before this kind of new automobile was still “old times Wang Xietang, amusement pure electric train the swallow”, “flew into the common family” with difficulty in the short time.
In summary, Chinese electric automobile profession, although the prospect has been obviously bright, but path actually still rough. Solves these challenge difficult problem, China’s electric automobile market can be strongly big.
Strikes root in the hearts of the people gradually along with the world environmental protection idea, the electric car profession’s technology several passes through the twists and turns, the date hastens the consummation, electric automobile finally in 21st century Cheng Wei the junction passes the profession the eminent.

Electric tour important component quality analysis
Electric tour buses currently reflected in the quality problems, the battery is the most, because the quality of the battery , the speed ultra GB , electrical power is too large to be a electric green car fundamental solution to these problems.
Resulting in poor quality for the following reasons :
1 , the vehicle motor power and battery capacity asymmetric configuration
Current electric tour buses , electric motorcycles, electric cars are mostly motor DC motor to a common hub motor , for example, the general efficiency is not high , brushed DC motor , and now the actual motor efficiency is very low, then the power voltage without changing its normal operating current is bound to increase . In this case , the actual input current of the motor requires a great inadvertently inevitably increase the battery discharge current. That is to ensure that electric vehicle speed , motor power is bound to increase . Motor starting current is generally normal driving current 3 to 5 times , uphill driving current of the motor current is three times the normal , which is a big gap .
Then there are brushless , brushed DC motors do not use a lot of the reduction gear , electric sightseeing car the direct use of electronic controller means the initial speed to the rated speed of the motor , such as 180 rpm -200 rev / min , so that the climbing pole load performance poor, working current greater damage to the battery plates , a direct result of decreased battery life and capacity .
2, the battery quality is poor
Powered rechargeable battery can be divided into two categories -and -start type for electric tour buses , boats collectively various battery -powered batteries , which requires a large current discharge can to accommodate traction motor start, acceleration load climbing requirements and other conditions . The currently used lead-acid batteries are slowly filling slow type , if the quick release is fast charging short life .
As the vehicle with the battery included in vehicle quality of its quality in other words to buy a new car , the battery replacement to reach the electric escort car commitment period , therefore, to take the vehicle auxiliary battery factory floor and had to pay after the guarantee period approach to the battery plant was ” baojia guilt” actually helpless.
3 , traffic , start , low speed, the motor current is large
Electric tour buses in the city riding , need regular stop , start, when driving a car fuel throttle to go out and accelerate quickly , speed up the spin motor controller to the most high-end ( speed ) , you know, the motor start to accelerate from a standstill when the output current of the battery is several times larger than the normal operating current exceeds the battery capacity, would surely damage the battery , the new battery can still withstand a few times , and when the battery life using 50% or 30 % Life time , can not withstand the impact of such a current .
4 , the quality of the charger and charging issues
Quality is good or bad for the battery charger is a great relationship longevity , universal electric lifting car charger package on the market today with eight months or even six months, because the charger price. Charger manufacturer price to win , OEMs to price orders. To reduce this , the charger manufacturer -order low- quality components , specifications, selection, ease of design and other causes of this situation, so there is ” not bad but the battery charge and the bad ,” one said unreasonable. In principle, should be equipped with the appropriate battery charger , battery and liquids such as colloidal battery is different, poor liquid and liquid -rich are also different , so the emphasis on quality of the battery manufacturers want their manufacture or optional battery charger is this factor.
5 , the controller quality problems
Now users complain controller life is short, easy to bad , because no more than a few , because the pursuit of low cost, in the design as simple as possible , as far as possible selection of low-cost components , and then have to involve motor power , current issues , because the controller is part of the specification model selection is based on the theory of electrical power , voltage and current above , then the efficiency of the motor problem ignore or do not pay attention , then the controller in practical work . Components are exposed to more than the original design of the current limit , coupled with in situ electric cars start to accelerate from rest to a top speed of rotation of the cyclist’s a few ms ( mm / sec ) between its current exceeds the electric garbage trucks design several times , so-called degree of experience is destructive .
Optimized electric tour vehicle design , testing the actual motor power, efficiency and vehicle speed , to ensure that the national standard allowed under the conditions of production. In addition to timely promotion, improved some of the GB parameters , in order to the national standard, and demand market demand and coordination between technology licensing in order to garbage vehicle achieve the best , strive for perfection.
