Electric vehicles (EVs) have been rapidly adopted in recent years, and the rate of market growth has shown to be significantly higher than that of the fuel-injected automotive market. Indeed, the global stock of electric cars surpassed five million in 2018.

The desire to reduce vehicle emissions, especially in densely populated areas, is driving the replacement of combustion engine-powered cars with electrical vehicles.

Developers of electric vehicles are on a very steep learning curve. Advancements seem to be emerging almost daily—especially as they relate to the power source, which includes battery pack design, engineering and assembly.
