Mitsubishi Heavy Industries Technical Review

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.
