The biggest application of lead acid batteries

IDTechEx has studied the biggest application of lead acid batteries - in cars - and finds that C category cars and above will have to be mild hybrids with 48V lithium-ion batteries and no lead acid batteries if they are to meet the tough new carbon dioxide emissions in 2025 and 2030 and exhibit up to four pure electric modes and enhanced performance to keep customers satisfied. That involves major electrification handling up to 20kW and a 1kWh battery by then. See the IDTechEx report Mild Hybrid 48V Vehicles 2016-2031 . Mild hybridisation at 48V (at minimum adding torque assist ie electrical boost function so engine can be downsized up to 60% and efficient regenerative braking) will push lead acid sales into sharp decline despite some of the B category being 48V mild hybrids by then with advanced lead acid. Fighting a rearguard action are a number of advances such as the o...
