Please refer to the manual for the charge and discharge limit of your inverter. When selecting the charge and discharge current limits you will always be limited to the lowest current value whether that is the inverter or the batteries. For example, the 3.6kW Ecco inverter has a 90A maximum charge/discharge current.
The power dissipated by the the inverter’s housi ng or through a cooling s ystem. the current. The discharge energy is used to charge the Low- voltage battery (12 V) us ed as an auxiliary bat tery. the Flyback transformer. A charging current of 1C is used to Ampere ho urs (Ah). The blue trace i n Fig.1 illustrates the energy
To control the voltage so that the voltage does not exceed 50 V (touch safe), the auxiliary power supply has to turn on and power up safety-relevant circuits that can discharge the DC link caps (active discharge) or actively short circuit the motor. Every EV traction inverter requires a DC link active discharge as a safety-critical function.
For example, the 3.6kW Ecco inverter has a 90A maximum charge/discharge current. Two 5.12/5.32kWh batteries have a continuous discharge of 100A. This means that the maximum charge/discharge is limited to the 90A of the inverter.
