Showing lead-acid to be a technical winner in hybrid vehicles has been at the heart of the ALABC research. Allan Cooper summarises a decade's worth of bench and road testing.
In the late 1990's the ALABC changed the focus from electric vehicle (EV) batteries to those for hybrid electric vehicles (HEV). While the specific energy of lead-acid batteries was too low for acceptable range in an EV, it had a perfectly acceptable power density to operate in HEVs. It had to be proven that valve-regulated lead-acid (VRLA) batteries were always going . . .
