Question:

How much is the battery charge for an electric bicycle?

nan

Answer:

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 key is to look at the size and capacity of the battery, the general 48V20Ah battery charge up to 1.5 degrees or so.
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.
The electric car battery is 12V 20AH, charging time is 6 hours. The charger is about 220V/1.2A. The power consumption of the charger is 264W. Electricity is 0.264 degrees per hour, and 6 hours is 1.58 degrees. According to the city electricity 0.8 yuan / degree calculation, each charge is 1.3 yuan.
