Depth of discharge (DoD): The depth of discharge specifies what percentage of the battery capacity has been used. For example, if a 10kWh nominal capacity battery has 5kWh stored in then its current DoD is 50% – if it has 2kWh left in storage then its DoD is 80%. Most batteries simply can''t be drained of all their stored …
