Given global concern over environmental issues and the implementation of regulations for carbon dioxide emissions, new battery technologies are required for hybrid electric vehicle (HEV) applications, especially for micro- and mild-hybrids. An evolution in the technology of lead–acid batteries commenced in 2000 and has now entered an accelerated stage. The use of carbon and the fast punching of lead to give thin grids have yielded high specific energy density and good cycle-life, as well as acceptable dynamic charge-acceptance and HRPSoC performance that meets the requirements of stop–start vehicles, micro-HEVs and mild-HEVs. The Asian automotive market of micro-HEVs is examined together with a forecast of the trends over next 10 years. New manufacturing processes for advanced lead–acid batteries are reviewed. The latest versions of international standards (IEC, EN, SBA-Japan, SAE, GB-China) for batteries employed in micro-HEV applications are also discussed together with the related regulations.
