Hark back to the subject, in the low-speed electric vehicle market, the mainstream low-speed electric vehicles per hour between the 40-55km/h, rarely to see speeds above 70km / h speed electric car.

Why not let the low speed electric cars run faster?

From the point of view of market demand. The low speed electric vehicles mainly to meet the village, urban elderly travel family short haul transport demand. And at present, this demand is mainly from the bicycle, electric tricycle, motorcycle to complete, and these consumer demand is the four round of the promotion of low speed electric vehicles. It is based on these requirements as well as the characteristics of consumer groups, low speed electric vehicles from the market level does not increase the demand for speed.

From the product cost point of view, the current low speed electric vehicles mainly use lead-acid batteries, and low speed electric vehicles to further enhance the speed to reach 80 or even 100km/h, the usual way is to replace the lead-acid batteries for lithium batteries. Changes in the use of lithium batteries, generally cost will increase of 8000 to 10000 yuan, which for the mainstream market, 2 to 3 million terminal price of low-speed electric vehicles, costs are undoubtedly amazing, manufacturers and consumers are difficult to accept.

From the technical feasibility (used lead-acid batteries), improve the low-speed electric vehicle speed need to consider replacing the greater power of motor, matching the current controller, and give full consideration to the lead-acid battery to withstand work pressure. Matching larger motors, the controller is not difficult also will not increase too much cost, however, the resulting large current discharge is fatal for lead-acid batteries.

Research and practice found that large current discharge will lead to lead acid lead to lead acid battery lead to lead to lead to lead to crystallization, resulting in a gradual decline in battery capacity, affecting battery life.

Thus, the positioning of the elderly group and the family in the town of low speed electric vehicles, from product positioning, market demand, the need to see and did not improve the speed.
