How much electricity does an electric car battery need to charge once?

Electric vehicles have become one of the choices for everyone's daily travel, and they are becoming more and more popular with consumers. So how many kilowatt-hours of electricity does an electric car use? 　　 First of all, it depends on the capacity of your battery, and secondly, when you are charging, what is the efficiency and power of the charger, including the charger. Rectifier. Note that it has nothing to do with how long you charge, because the charging current is very different, and the time does not explain the problem.　　 If your battery is 100, and it starts after you turn on the battery to completely use up the photocurrent. Then, the electricity used for a charge is 1 thousand times 0.1 to 0.1 degrees.　　 If it is another capacity, you can install this multiplier, 40 is 0.04 degrees. Then calculate the efficiency of the charger, multiply the efficiency, and add the heat loss during charging.　　 You can simply calculate from another angle. In the manual of the electric vehicle, the number of kilometers for full battery to continue is indicated, generally 50Km, and the power consumption per hundred kilometers, for example, if the power consumption per hundred kilometers is 1.2 degrees, the power consumption per kilometer is 1.2/100u003d0.012 degrees. , Assuming that if you travel 25 kilometers a day on average, you need to charge once in two days, and the daily power consumption is 0.012X25u003d0.3 degrees, that is, it takes 0.6 degrees to charge once in two days, which is 9 degrees in a month, less than 6 yuan, Rarely. The data provided by the manufacturer is tested under standard conditions, and there may be slight discrepancies according to different seasons and road conditions.
