Electric vehicles use batteries as an energy source to drive electric motors. Lead-acid battery is a battery used since the first appearance of electric vehicles in the late 1800s.
Lead Acid. Lead-acid batteries contain lead grids, or plates, surrounded by an electrolyte of sulfuric acid. A 12-volt lead-acid battery consists of six cells in series within a single case. Lead-acid batteries that power a vehicle starter live under the hood and need to be capable of starting the vehicle from temperatures as low as -40°.
In lead-acid batteries, internal resistive losses (Joule heating) occur with each cycle, converting energy to heat, lowering efficiency and capacity. Temperature affects lead-acid batteries similarly, with high temperatures increasing resistance and self-discharge, and low temperatures impacting performance [9].
For each 10°F rise in temperature, the life of a sealed lead acid battery is cut in half. Therefore, if a battery in a stationary position that should last for 4 years at normal temps, would last 2 years if exposed 92°F and even less if exposed to typical desert temps of 106°F.
Valve Regulated Lead-Acid (VRLA) batteries have a rated design life capacity based on an optimum operating temperature of 20-25°C. For every 10°C constant increase in temperature above this recommendation, it is generally accepted that battery service life will halve (reduce by 50%).
