The battery discharge rate is the amount of current that a battery can provide in a given time. It is usually expressed in amperes (A) or milliamperes (mA). The higher the discharge rate, the more power the battery can provide. To calculate the battery discharge rate, you need to know the capacity of the battery and the voltage.
The faster a battery can discharge, the higher its discharge rate. To calculate a battery’s discharge rate, simply divide the battery’s capacity (measured in amp-hours) by its discharge time (measured in hours). For example, if a battery has a capacity of 3 amp-hours and can be discharged in 1 hour, its discharge rate would be 3 amps.
That means that it can provide 2.4 A of current for one hour, or 1.2 A for two hours before it needs to be recharged. Higher discharge rates are generally better since they allow the battery to power devices that require high levels of current (such as digital cameras and flashlights).
The discharge rate is usually expressed in terms of amperes (A) or milliamperes (mA). For example, a common AA battery has a discharge rate of about 2.4 A. That means that it can provide 2.4 A of current for one hour, or 1.2 A for two hours before it needs to be recharged.
Battery discharge efficiency is the amount of power that a battery can deliver over time compared to the amount of power it takes to charge the battery. The higher the discharge efficiency, the more power the battery can provide. There are several factors that affect battery discharge efficiency, including:
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.
