48v350w electric cars, how much work current?
The starting current, climbing wave and cross current are from 10 to 12A, and the current is 7~8A at uniform speed.General 48V350W electric vehicles with batteries for 48V12AH, theoretical mileage of up to 49 kilometers, when the power of the same motor, the larger the battery capacity, mileage will be further. Lead acid battery technology is mainly based in China, and Japanese batteries are not comparable to domestic power batteries.
When the load increases, the motor output torque increases, power increases, at this time the mileage will be less. With traffic conditions, environmental temperature is also related to, when the road often climb or start, the mileage will be shortened, because climbing wave and starting current than the average current is larger, so the time will be shortened. The change of the environment temperature also affects the battery capacity, the higher the temperature, the capacity will be slightly higher, the lower the temperature, the capacity will be slightly lower.
The theoretical mileage is calculated as follows:1) uniform average current = power / voltage =350W/48V=7.3A;2) travel time = battery capacity / average current =12AH/7.3A=1.64 hours;3) according to the speed of 30 kilometers per hour, the theoretical mileage of =1.64*30=49 kilometers.
