Mitsubishi Heavy Industries Automot ive Thermal Systems Co., Ltd.
Mitsubishi Heavy Industries Automotive Thermal Systems Co., Ltd. has developed and
manufactured electric water heaters for heating the interior of electric vehicles (EVs) or plug-in
hybrid electric vehicles (PHEVs) since 2009. In EV heating systems, electric water heaters serve as
a heat source (as a substitute for engine waste heat). In PHEVs, the use of electric water heaters
eliminates the need to run the car's engine to obtain a working heat source, which as a result can
contribute to better fuel economy.
This report introduces our new models of electric water heaters (Generation 3), which feature
better functionality than the previous model.
