Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
A battery in a satellite has a typical DoD of 30–40 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.
Batteries are seldom fully discharged, and manufacturers often use the 80 percent depth-of-discharge (DoD) formula to rate a battery. This means that only 80 percent of the available energy is delivered and 20 percent remains in reserve.
With a higher discharge current, of say 40A, the capacity might fall to 400Ah. In other words, by increasing the discharge current by a factor of about 7, the overall capacity of the battery has fallen by 33%. It is very important to look at the capacity of the battery in Ah and the discharge current in A.
The discharge current would have to be 400A to discharge the battery in an hour. If the battery has a C20 capacity of 600Ah, it means that when the battery is discharged in 20 hours, it has a capacity of 600Ah. The discharge current would have to be 30A to discharge the battery in 20 hours (600Ah / 20h).
However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery. In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery.

Get PriceIn this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery. For example, a battery capacity of 500 Ah that is theoretically discharged to its cut-off voltage in 20 hours will have a discharge rate of 500 Ah/20 h = 25 A. Furthermore, if the battery is a 12V ...
