After a full discharge, the electric vehicle needs about 0.65 to 1.08 KWH of electricity (using a 48V battery as an example) on a single charge.
1, first of all, there are many models of electric vehicle batteries, including 48V, 60V, etc., but due to the implementation of the new national standard, there is a clear limit on battery voltage. Therefore, today we will talk more about 48V electric vehicle batteries.
2, Taking the 48V20AH battery as an example, its average charging voltage is about 51.6V, plus the need to charge the electricity is 1.05 times the amount of electricity released, therefore, the charge consumes about 1.08 degrees of electricity (the consumption of electricity = average charging voltage * rated capacity of the battery *1.05).
3, it should be noted here that there may be the same pressure but different capacity of the battery, once the capacity is low, then its power consumption will be relatively low, such as 48V12AH battery, the general power consumption of a charge is 0.65 degrees of electricity. Therefore, the greater the voltage and capacity, the more electricity required for a single charge.
4, in addition, one thing can be explained to you is that the general electric vehicle battery is fully discharged, within 8 to 10 hours can be full, which means that its 48V20AH battery power consumption per hour is about 0.1 to 0.13 degrees, and 48V12AH battery power consumption per hour is about 0.06 to 0.08 degrees. It can also be seen that in fact, charging an electric car does not consume as much power as imagined.
5, the above is also full discharge, in fact, under normal circumstances, when the electric vehicle battery power is less than 30%, it needs to be charged immediately, which can prevent excessive discharge and damage the electric vehicle battery. In addition, electric vehicles can not be charged with the charge, because lead-acid batteries have a certain number of charges and discharges, if frequently charged, will shorten its life.
6, in short, after full discharge, to charge the electric vehicle battery, a full need for about 0.65 to 1.08 KWH (48V battery as an example). For users, when charging electric vehicles daily, they also need to reasonably control the charging time.
The temperature of the electric vehicle rechargeable battery is about 25-45 ° C, that is, the hand does not feel hot, which is considered normal; In case of abnormal heating, power off and eliminate the problem in time to avoid thermal runaway; In addition, please charge in a dry, ventilated, no direct sun environment, do not charge in the sun exposure, it is easy to occur spontaneous combustion risk; Do not park electric vehicles in closed Spaces such as indoor and corridor charging, and do not occupy and block evacuation channels and safety exits.
