In the use of electric vehicles, I believe that many users have such a question: to charge the battery of electric vehicles, how many degrees of electricity?How much electricity does one kilometer consume?And for this question, small make up today with the most common 48V20AH and 60V20AH electric vehicles to discuss in detail with you.

First, we need to know how to calculate a charge.It is output voltage * output current * charging time.Take an electric vehicle of 48V20AH as an example, its output voltage is about 60V, and its output current is about 2.5a. Assuming that the charging time of the electric vehicle from no power to full power is 8 hours, then it needs about 1.2 kilowatt-hour (60V* 2.5a *8h=1.2 kilowatt/hour).

However, for the 60V20AH electric vehicle, the output voltage is about 72V, while the output current is still 2.5a, and the charging time is also 8 hours, so one charge is about 1.44 ° C. Second, we need to know how to calculate the ev's range.Is the average speed * travel time.Take an electric vehicle of 48V20AH as an example, its average uniform current is 12.5A, from which we can know that the theoretical travel time is 1.6h (travel time = battery capacity/average current =20AH/ 12.5a =1.6h). Assuming that the average speed of an electric vehicle of 48V20AH is 35km/h, the range is 56km (35km/h*1.6h=56km).

Similarly, the average uniform current of an electric vehicle with 60V20AH is 10A, from which we can know that the theoretical travel time is 2H. Assuming that the average speed of an electric vehicle with 60V20AH is 35km/h, its range is about 70km.

From the above data, we can know that a 48V20AH electric vehicle needs about 1.2 KWH per charge, while a kilometer consumes about 0.02 KWH (1.2 KWH /56km=0.02 KWH/km).However, a 60V20AH electric vehicle needs about 1.44 KWH per charge, while a kilometer consumes about 0.02 KWH (1.44 KWH /70km=0.02 KWH/km).

However, the data for each car can vary slightly depending on the season and driving habits.But overall, the electric bike only consumes about 0.02 degrees per kilometer on a single charge.Compared with other means of transportation, it is a real benefit.For users who ride electric bikes on their daily trips, they can ride safely.So, what do you think?
