A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge.
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 is an electrical component that is designed to store electrical charge (or in other words - electric current) within it. Whenever a load is connected to the battery, it draws current from the battery, resulting in battery discharge. Battery discharge could be understood to be a phenomenon in which the battery gets depleted of its charge.
Maximum Continuous Discharge Current – The maximum current at which the battery can be discharged continuously. 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.
In many types of batteries, the full energy stored in the battery cannot be withdrawn (in other words, the battery cannot be fully discharged) without causing serious, and often irreparable damage to the battery. The Depth of Discharge (DOD) of a battery determines the fraction of power that can be withdrawn from the battery.
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.
For the discharge process to be performed in safe conditions, besides gathering information about the battery's capacity, SoC and SoH at the beginning of the process it is necessary to monitor the temperature and voltage of individual modules, preferably even groups of cells, as well as to control the discharge current.
