- Q: How much is the battery charge for an electric bicycle?
- Battery capacity is 20A h, meaning is: to the discharge current of 20A can last for an hour, it can be concluded that the calculation method: 60V * 20A * h/1000=1200VA * h=1.2KW * H (VA=W, 1KW=1000W) depending on the residual capacity of your battery and charger output efficiency (ETA) and.The 60 volt battery: 20 MA (60V20HA) every time full of electricity; set battery capacity is 20AH, voltage is 60V, a full charge is 60V * 20AH=1200WH=1.2kwh, the actual charging efficiency is 75%, so 1.2kwh/75%=1.6kwh, 60V, 20AH of the electric tricycle battery each filled with a TV about the need for 1.6kwh, namely 1.6 degrees.
