DENSO, Toyota want your EV to power your home

DENSO Corp. has developed a vehicle-to-home (V2H) power supply system for electric vehicles (EV), which is designed to work in coordination with DENSO’s home energy management system (HEMS).

“DENSO and Toyota are working together to develop a V2H power supply system that uses alternating current, and have been conducting demonstration tests using plug-in hybrid vehicles (PHV) to ensure the system can efficiently use energy,” said Hikaru Sugi, senior executive director of DENSO's Engineering Research and Development Center and CEO and president of DENSO International America, Inc.

“With our newly developed system, we will now perform demonstration tests on a V2H power supply system that can be also used for EV’s.”

The V2H system can quickly charge an EV with direct current from the HEMS storage battery, and can supply the electricity in the EV back to the household. In addition, the system can efficiently distribute electricity, including power generated by residential photovoltaic systems (solar panels), to the EV and to the home through the coordination of the HEMS.
