In the low-speed electric vehicle market, mainstream low-speed electric vehicles usually range from 40 to 55 kilometers per hour. Rarely, low-speed electric vehicles with a speed exceeding 70 km/h.
Why not make low-speed electric vehicles run faster?
From the perspective of market demand. The design of low -speed electric vehicles is to meet the travel needs of rural areas and urban elderly and short-distance transportation needs of the family. At present, this demand is mainly met by bicycles, electric tricycles, and motorcycles. These consumers demand to promote the driving force of low-speed four-wheel electric vehicles. At the same time, according to the requirements of the State Administration of Transportation, the use scenarios are mostly in urban and rural areas. The speed limit of these roads is generally 40-60km/h. Some countries stipulate it doesn’t need a driver’s license to drive a car with a top speed of 25 km/h-45 km/h.
According to these requirements and the characteristics of the consumer group, from the market level, there is no need to increase the speed of low-speed electric vehicles.
From the aspect of product cost. At present, low-speed electric vehicles mainly use lead-acid batteries. If we want to further increase the speed of low -speed electric vehicles to 80 kilometers or even 100 kilometers per hour, the usual method is to replace lead-acid batteries with lithium batteries. This change in batteries usually increases $ 1,300 to $ 1,600. For low-speed electric vehicles with a final price of 20,000 to 40,000 RMB in the mainstream market, this cost is undoubtedly amazing, and it is difficult for manufacturers and consumers to accept it.
From a technical feasibility perspective (using lead-acid batteries). In order to improve the speed of low -speed electric vehicles, we need to consider using greater power to replace the motor, match the corresponding current controller, and completely consider the work pressure that the lead-acid battery can withstand. It is not difficult to match the electric motor and controller to match a greater power matching, and it will not increase the cost too much. However, the generated large current emissions are fatal to lead-acid batteries.
Research and practice show that larger current emissions can lead to lead crystals of lead -acid batteries, resulting in a gradually decreased by battery capacity and affecting battery life.
Therefore, low-speed electric vehicles for the elderly and urban families do not need to increase the speed from all aspects of product positioning and market demand.
However, due to the diversity of market demand, our company has also made 80km/h electric vehicles. There are no technical problems manufacturing 70-80km/h. We changed the chassis, and suspension, thickened the body, aggravated the weight of the body, and make the body more secure and comfortable during driving.
