Batteries for Passenger Vehicles

Vehicles powered by internal combustion engines represent the majority of the automotive market. They use lead-acid batteries to start the vehicle and power accessories. These batteries need to be reliable and, as electrical systems become more demanding, increasingly durable.

Start-stop vehicles use internal combustion engines that automatically shut off when the car is idling, then restart when the driver’s foot leaves the brake pedal. When the engine is off, the vehicle’s electrical system uses energy from the battery. The battery is used to restart the engine after each stopping event. Start-stop vehicles provide up to 5 percent more fuel-efficiency and reduced CO₂ emissions.

Advanced start-stop vehicles further enhance fuel efficiency through added capabilities such as engine-off coasting, electric boost and regenerative braking. These vehicles are 5–8 percent more efficient that internal combustion engine powered vehicles, and help automakers meet stringent fuel efficiency regulations without major changes to conventional powertrains and electrical systems. Advanced start-stop vehicles use two batteries, a 12 volt lead-acid battery and a 12 volt lithium-ion battery.

These vehicles extend start-stop functionality even further. They use two batteries: a 12-volt lead-acid battery starts the engine and powers accessories; a 48-volt lithium-ion battery captures power from regenerative braking and powers high-load functions such as electric air conditioning, active chassis technology, and an electric traction motor that supplements the internal combustion engine to propel the vehicle. Micro-hybrid vehicles are 12–15 percent more efficient than conventional internal combustion engine powered vehicles.

Hybrid electric vehicles (HEVs) are powered by both an internal combustion engine and a high-voltage electric battery that is recharged by the internal combustion engine. HEVs are 20–40 percent more efficient than conventional vehicles powered by an internal combustion engine alone, and are an important part of the solution to meet longer-term fuel efficiency and admissions regulations without compromising vehicle range. HEVs use two batteries, a 12 volt lead-acid battery and a high-voltage lithium-ion battery.
