Grizzl-E Duo Intelligent Power Sharing

Grizzl-E Duo features intelligent power sharing to charge two electric vehicles at the same time.

Grizzl-E Duo’s power sharing algorithm shares amperage between two vehicles in the following manner:

1. If one vehicle is connected to Duo, then the maximum amperage (40A,32A, 24A,16A based on DIP Switch settings) is available for this vehicle.
2. If two vehicles are connected, then the maximum available amperage is divided evenly between the two vehicles (Example: 40A / 2 = 20A for each vehicle).
3. If two vehicles are connected and one vehicle goes to state ‘Charging Complete’, then 8A is dedicated to the completed vehicle. The remainder of the amperage is available for the other vehicle (Example: 40A – 8A = 32A).
4. If both vehicles are completed 8A are available for both vehicles. If one completed vehicle goes to a Charging state again, then 32A will be available for this vehicle. If the second vehicle goes to a Charging State the amperage will gradually split 50/50 again.

See Chapter 7.4 Grizzl-E Duo Output Distribution and Indicator Lights on page 22 for a full list of power distribution and indicator lights.

Stop Charging

1. Unplug the charging station by pressing the connector button and removing the Charger Connector from the EV (once the connector button is depressed, the charging session terminates immediately).
