| Example 2. The battery voltage is 600V in initial, the maximum charging current (Max charging current) is 100A, the requested charging power (Target active power) is 50kW, the PWS2-30K will charge in 50kW, because the charging DC current is just $50kW\div 600V=83A$, and as the voltage rises, such as 660V, the power is still 50kW, because the charging DC current is $50kW\div 660V=76A$. But if 670V is the constant voltage charging threshold set by user, when the voltage reaches 670V, the power will reduce gradually till 0. | Example 2.
