How much power is required for battery full charge?

Electricity fee = electricity (degree) * electricity bill price (yuan) Here everyone says = kWh Here we call unit price: 1.5 yuan / kWh (subject to actual price) Depending on the above data: Rated capacity: 560ah (5h refers to 5 hours of discharge rate in China) Rated voltage: 48V Electric bill price: 1.5 yuan / kWh Energy (kWh kWh) = voltage (V)×Current (a)×Time (h) Then we must know the current (a) now. The current here refers to the charger of the charge current 560ah charger is generally equipped with an 80A charger. Current = 80A (Charging machine current is generally rated * 0.14) For the above charger is full of electricity than 8-12h, we will take time = 10h Then, according to the formula, it can calculate the battery full charge: Electricity = 48V * 80A * 10H = 38400Wh = 38.4kWh = 38.4 degrees Electricity fee = electricity * electricity bill price = 38.4 * 1.5 yuan = 57.6 yuan Let's take a look at how much electricity charges are required for 48V 280AH. Electricity fee = 1.5 yuan * 48V * 280AH * 0.14 * 10H / 1000 (divided by 1000 is whip conversion as KWH) = 28.224 yuan Some friends see the above formula may say that now there is only 4-6 hours now, this calculation formula is not right, in fact, the quick charging method is simple to increase the current, when the time is 4-6 hours At the time, it is necessary to know that the current of the fast charger can be several times the general charger. Of course, I also see another formula for calculating electricity bills. Calculate 48V 280AH Electricity fee = 1.5 yuan * 280AH * 48V * 1.2 / 0.85 / 1000 = 28.46 0.85 is a chargeable efficiency 1.2 for charging capacity 1000 is whip converted to kWh Expand The current is multiplied by time is the capacity of the battery, reads——Mas, she does not meet the recoverable calculation of the unit in the electrical unit.
