A battery in a satellite has a typical DoD of 30β40 percent before the batteries are recharged during the satellite day. A new EV battery may only charge to 80 percent and discharge to 30 percent. This bandwidth gradually widens as the battery fades to provide identical driving distances. Avoiding full charges and discharges reduces battery stress.
Manual discharge techniques involve connecting an external load to the battery to drain its charge. This can be done using a battery discharger or any other load that is suitable for the battery's specifications. The load current should be monitored to prevent over-discharging and damage to the battery.
