Four key to distinguish the merits of electric motor vehicles

Electric car motors like the electric car "heart", the same set of 48V 20AH lead-acid batteries, high-quality good efficiency of the motor can run 45-55 km, so buy electric car must pay attention to choose high-quality accessories. So how can we distinguish the cargo electric bike motor and cons?
Since the motor is sealed, if it's good or bad judgment fundamentally, it needs some external tools, such as words table. In addition to the help of professional tool, you can also be judged from the appearance of materials and general performance. The above methods can simply be attributed to: a look at two three four touch detection.
A look: Look housing. The outer plating work to do good motors general appearance of relatively bright, refurbished machines gray and relatively dim. Then you can see the motor marks, generally larger manufacturers will be marked with the brand value development, which is a manifestation of the brand quality. Finally, you can see whether the motor 3C certification, motors comply with industry standards will be more secure.
Second touch: touch temperature. After the motor has stopped consumers can hand to sense temperature of the motor, the lower the temperature, the better the motor heat dissipation, the better the performance.
Three: to listen to power. When commissioning, consumers can load start-up power is abundant, with plenty of power is not likely to cut corners on the motor coil.
Tetra Detector: sense resistor. 1, the detection phase AC motor is good or bad shake table, 500V shake table to shake the three terminal lines on the insulation resistance of the motor housing, in 0.5M over Europe it means not to be short-circuited. 2, multimeter test: test A / B / C three phases of the resistance, are equal. The larger the difference between the value of the motor performance worse. And the greater the motor power, the smaller the resistance! But not the three-phase are zero in Europe, except as above 50KW motor particularly large, but the current foldable bike electric applications can say no.

Electric cars to choose brands

As the electric vehicle market wide variety of brands, a variety of promotions are endless, which leads people to buy electric cars dilemma, do not know how to buy electric cars. For this reason he visited the owner of a motor vehicle shop Gaomi Chang An Avenue, the southern section of reporters. The store owner told reporters, first of all, at the same time focus on the purchase of electric car models should try to choose the large production of brand electric vehicles, not only quality and security, and after the electric car problems, aftermarket can help solve the problem instead of shirking responsibility. "Buy electric vehicle owners to look at the configuration." According to reports, the various components of adult electric tricycles are assembled in selecting the electric car, be sure to select the components are big brands, guaranteed.
In addition, buy electric cars must be carefully optimistic about the four major components: motor, battery, controller, charger. After selecting your favorite folding electric trikes, be sure to try to ride it, check the brakes, and the car off various parts of the switch function is normal. The brand is a symbol of quality, the quality of different brands, different levels of consumers in the purchase be sure to choose the authority of the department, and the proven quality, reliability, low repair rate, good service, high credibility of the brand.

How to properly charge the battery for electric cars?

Electric car has now become life will not lack means of transport, basically every household should have one, then you know how to correct to charge it? Many people do not know the electric car battery should be no electricity and then charge it, or a little on the charge of electricity shortage problem. Now riding the electric car on the street more and more friends, but the right way to electric vehicle battery charging lack of know very few. Today, in relation to how to charge the battery electric adult tricycles for everyone to talk about:
1, to keep the battery full power state, riding electric assist tricycles every day, regardless of 10-50km, should supplement charge the battery a long period of "eat state", and the same day on the charge, spent idle days recharging and easy appear plate curing, capacity decline.
2, periodic deep discharge: It is recommended that you use for two months after the binary conduct a deep discharge, the long-distance riding until the voltage indicator flashes, power runs out, then resume charging the battery capacity, but also lets you know the battery The current capacity level, whether by maintaining protection.
3, prohibit loss of electricity storage: storage battery power loss will seriously affect the life, if left idle for longer, more serious damage to the battery.
4, regular inspection: if you buy a new car to continue the mileage of 50km, continuation line was severely reduced, such as a dozen kilometers, this time outside the terminal used multimeter to check the battery voltage value is present within three months, the general should be charged 39 -42V, if less several volts, or open the battery case in which a battery voltage is lower than 10.5V, a single cell could be an internal short circuit, and you should find a service station to repair replace the battery to avoid damage to the other two. There is also the fault of the charger should be checked.

Extend electric vehicle battery life to see here

Electric vehicle battery life not only determines the level of user comfort, but decided the cost of household expenditure. For ordinary users, the electric vehicle battery the longer, lower costs, so many people in the choice of all shop around, trying to find a cheap and used live electric car battery brand. Why are some people's cell 2035 is still used, some one and a half to be scrapped? Because the former is good maintenance. So, how maintenance can extend the battery life of it?
First, ground maintenance
Although mountain electric bicycle like bicycles require frequent use as axles, flywheel, but also need maintenance. Especially after a long ride, the car appeared slow-moving situation, more importantly, to care about it. How to do it? Very simple, just based on their usage and maintenance of the car to scrub, during maintenance, various places around the shaft axis and a flywheel, fork, etc. must be taken into account.
Second, the handling charge
Through the survey we found that thirty percent of the people in charge when the electric cargo bicycles is slow, sometimes to the release of all power to do, and can not be used, charging only think of it, this approach is not good, give the battery cause more damage. So, how to charge it? It suggests the best power drops to 50 percent when they charge 30 percent would stop riding. If it is not long, but also plenty of a battery, then one charge each month.
Third, ground check
Electric vehicle battery inspection and maintenance is often performed. During the inspections, should pay attention to the surface of the battery is in good condition, if there are damaged areas, whether there are other unusual places, we must look closely.

Electric bicycle industry has "Lithium" walk the world

More environmentally friendly energy compared to traditional lead-acid batteries, the same specification lithium-ion battery life of about three times as one-third the weight and volume of only the former, and. Industry innovation capability significantly enhanced, rapid increases in value-added products, after-sales service system are maturing, becoming the lithium-ion battery electric bicycle most competitive
China's lithium New Energy Industry Forum held recently, the industry generally believe that lithium-based electric bike is a trend. "This year, the annual output of more than 3 million have been no suspense" China Bicycle Industry Association Super horse, said the electric Mountainbikes would have an estimated lithium scale may have four or five years, it now appears that this trend is advance to, electric bicycle industry has become a highlight of the new energy and new applications.
Compared to conventional electric bicycle commonly used lead-acid batteries, the same size lithium manganese oxide and lithium iron phosphate lithium-ion battery life of about three times as one-third the weight and volume of only the former, and more environmental protection and energy saving. Professor, Department of Applied Chemistry, Peking University their Lu said that in 2014 power lithium battery industry has begun explosive growth, we are in a "Lithium" traveled the world in the era.
In addition to technical and performance advantages, why talk about lithium battery electric adult tricycles every year to a new level, Super horse-depth analysis. First, some local governments and departments to quickly regulate electric bicycle safety driving, increasingly strict regulatory environment, but highlights the lithium-ion battery electric bicycle light, security, etc; the second is the state's new energy industry for many years of support and training, to the lithium-ion battery industry best boost power; third industry gathering continues to increase, industry innovation capability significantly enhanced, rapid increases in value-added products, after-sales service system are maturing, becoming the lithium-ion battery electric bicycle most competitive .

How safe driving electric bicycles

Safety standards must be used in line with national requirements helmet, size appropriate to the size of the head. To properly fastened when driving the belt, if the helmet visor with a scar mask, can cause irregular reflection of light, thus restricting the view, do not use. Effect of sight when the sun do not use masks. In addition, the 3 wheel electric bicycles helmets and other reasons due to turn fall damage, please do not use.
Pre-departure preparation: check brakes, tires, batteries, engine, headlights and turn indicators, routine inspections to once every day before riding. Ride electric assist tricycles will be started, from riding the road ahead left and right sides start to your back for confirmation, and send a signal with turn signals, after confirming safety, and slowly increase the throttle, start the vehicle.
Night driving speed should be lower than during the day, and as close to the middle of the road-right direction of travel, night driving distance between vehicles is generally 50 meters. We should be able to skillfully transform lighting and correctly judge the road conditions, but basically to travel beyond the light. We found the opposite vehicles, bicycles and pedestrians to slow down, and switch to low beam lights, if lights other vehicles themselves dizzy, they should immediately pull over with, if necessary, take the initiative to stop and yield.
