How long does it take to charge an electric bicycle once?

After full discharge, it takes about 0.65 to 1.08 kWh to charge an electric vehicle once (taking a 48V battery as an example).

1. First of all, there are many kinds of batteries for electric vehicles, including 48V and 60V. However, due to the implementation of the new national standard, the battery voltage has been clearly limited. Therefore, today we will talk more about 48V batteries for electric vehicles.

2. Take the 48V20AH battery as an example, its average charging voltage is about 5 1.6V, and the amount of electricity to be charged is 1.05 times of the discharged amount, so it consumes about 1.08kWh (power consumption = average charging voltage * battery rated capacity *1.

It should be noted here that all batteries can have the same voltage, but different capacities. Once the capacity is low, the power consumption is relatively low. For example, for a 48V 12AH battery, the power consumption at one charge is generally 0.65 kWh. Therefore, the greater the voltage and capacity, the more power is needed for one charge.

4. In addition, it can be explained to you that the battery of an electric vehicle can be fully charged within 8 to 10 hours after complete discharge, that is to say, the power consumption of its 48V20AH battery is about 0. 1 to 0. 13 degrees per hour, while the power consumption of its 48V 12AH battery is about 0. 0 per hour. It can also be seen that in fact, charging an electric car once is not as power-consuming as expected.

5. Of course, the above is also a complete discharge. In fact, under normal circumstances, when the battery of electric vehicle is less than 30%, it needs to be charged immediately, which can prevent excessive discharge and damage the battery of electric vehicle. In addition, electric vehicles cannot be charged by charging, because lead-acid batteries have a certain number of charging and discharging times, and if they are frequently charged, their life will be shortened.

6. In short, it takes about 0.65 to 1.08 kWh to charge the battery of an electric vehicle after it is completely discharged (taking a 48V battery as an example). For users, it is also necessary to control the charging time reasonably when charging electric vehicles daily.
