A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.
A 48 V system can provide more power, improve energy recuperation, [7] and allow up to an 85% decrease in cable mass. [10]12-volt systems can provide only 3.5 kilowatts, while a 48 V power could achieve 15 to 20 kW or even 50 kW. 48 volts is below the level that is considered safe in dry conditions without special protective measures.

SLI batteries (starting, lighting, ignition; e.g., car batteries) suffer the most deterioration because vehicles normally stand unused for relatively long periods of time. Deep-cycle and motive power batteries are subjected to regular controlled overcharging, eventually failing due to corrosion of the positive plate grids rather than sulfation.

German carmaker Audi and utility EnBW are setting up an electric car battery operation at EnBW's Heilbronn plant to build scaleable storage facilities by the end of this year, drawing on retired ...
Audi paused production of the e-tron in February 2020 due to supply chain problems including issues with adequate supply of batteries for the e-tron. [25] Production resumed in early May. [26] In 2022, Audi announced that the facelifted e-tron will be renamed to Audi Q8 e-tron (unrelated to the existing Audi Q8) which was revealed at 9 November ...
Audi A3 TDI Clubsport quattro is a concept car unveiled in 2008. Based on the Audi A3 three-door, it is an approach by Audi to address both performance and the environment. The engine in the concept car is a turbocharged 2.0-litre diesel producing 224 hp (167 kW) and 332 lb⋅ft (450 N⋅m) of torque.
Nickel–zinc batteries have a charge–discharge curve similar to 1.2 V NiCd or NiMH cells, but with a higher 1.6 V nominal voltage. [5]Nickel–zinc batteries perform well in high-drain applications, and may have the potential to replace lead–acid batteries because of their higher energy-to-mass ratio and higher power-to-mass ratio – as little as 25% of the mass for the same power.
