Electric Car Battery Degradation Causes

The chemistry of lithium-ion batteries, which are frequently used in electric vehicles, is one of the main electric car battery degradation cause.

Electrochemical reactions occur inside the battery during the charging and discharging cycles, resulting in chemical alterations that gradually reduce the battery’s capacity over time. Additionally, the capacity of the battery is further diminished by the consumption of active lithium ions during the creation of a solid-electrolyte interface (SEI) layer on the electrode surfaces.

Battery degradation is additionally impacted by high temperatures. Due to their sensitivity to temperature extremes, electric car batteries can degrade more quickly when exposed to high temperatures.

High ambient temperatures and heat produced during charging and discharging might cause thermal stress and shorten the life of the battery. This problem can be made worse by inadequate heat dissipation, such as inadequate cooling systems.

Fast charging, especially when using high-power chargers, can potentially speed up battery aging. Rapid charging creates more heat, which stresses the battery and quickens deterioration.

Frequent quick charging sessions, particularly those that don’t give the battery enough time to cool down between charges, might accelerate the degrading process. It’s important to remember that battery degradation happens gradually, and modern electric cars are built to lessen their effects.

The use of advanced battery management systems, temperature management systems, and charging algorithms that maximize battery health are just a few of the measures manufacturers use to reduce degradation.

Regular care, such as avoiding high temperatures and charging in accordance with the manufacturer’s instructions, can slow down battery deterioration and increase battery life.
