Energy and Power of a Lead-Acid Battery Cell

6 Energy and Power of a Lead-Acid Battery Cell 

The amount of energy transferred to a battery during charge or delivered by a battery during discharge (E under constant-current condition is given by the following expressions  

When the discharge current increases, the energy delivered by the battery decreases. Therefore, for traction applications, or when the battery is used to supply 

FIGURE 1.13 Capacity (10-h discharge rate) versus temperature. 

The ratio between the energy utilized during discharge E and the energy consumed during charge is known as the energy coefficient (WhE)
