A123: Increasing 48V battery power up to ~25 kW enables advanced mild hybrid capabilities with greater fuel savings

Green Car Congress

Improving battery power to such as level would further enable hybridization to near-HEV levels as well as engine downsizing, thereby enabling fuel economy improvements beyond the current 10-15% MHEV limit. The BISG is connected to a 48 V (nominal battery) and also typically to a 12V powernet via a DC/DC convertor. —Abdellahi et al.

Marks & Spencer to lease Dearman zero-emission TRU

Green Car Congress

The Dearman transport refrigeration system combines cryogenic refrigeration with a Dearman engine and a downsized vapor compression refrigeration cycle, giving it several decisive advantages. It now plans to go even further in cutting its carbon emissions and in June 2017 launched its new sustainability plan: Plan A 2025.
