In addition to the battery's own bottleneck, peripheral charging devices have their own limitations. Simply speaking, the higher the output power of charging pile is, the shorter the charging time is. However, the charging pile can not improve the charging power indefinitely. Let's take a look at the process of charging an electric car.
When it comes to car charging, the first thing that comes to mind is the charging pile. Simply speaking, the higher the output power of charging pile is, the smaller the battery capacity is, and the shorter the charging time is naturally. This is the same as filling a pool with water. The bigger the pipe, the smaller the pool, the shorter the time. However, as electric vehicle users, of course, they want their battery capacity to be large enough, so it is more natural to improve the power of the charging pile. Charging piles for vehicles are generally divided into AC charging piles and DC charging piles. Let's do it in two separate cases.
First, the ac charging pile with strong universality. It mostly uses 220V AC charging as the household voltage, the general current is only 16A or 32A, the charging speed is relatively slow, in the case of battery capacity of about 20kwh, it takes about 6-8 hours to be fully charged.
