Toyota’s Power Supply System Allows Fuel Cell Buses to be Used for Disaster Management

Toyota Fuel Cell Bus Power Supply System

Toyota Motor Corporation (TMC) has developed a power supply system that uses electricity generated by a fuel cell bus to run electronic equipment. This will allow fuel cell buses to function as mobile power supplies that can be used at places such as evacuation centres following disasters.

The ‘power supply’ bus is based on the FCHV-BUS, Toyota’s fuel cell bus model that is currently in use on various routes in Japan, such as within the environs of the Central Japan International Airport, between the Tokyo International Airport and the Tokyo metropolitan area, and within Toyota City. A bus equipped with the new power supply system has two electrical outlets (AC 100 V, 1.5 kW) inside the cabin that can supply a maximum output of 3 kW and potentially power home appliances continuously for more than 100 hours.

As part of the comprehensive disaster-control training to be conducted by Aichi Prefecture and Toyota City on 2 September, the system will be used to power approximately 20 information display monitors inside a disaster control headquarters tent.

TMC has already developed a vehicle-to-home (V2H) system for supplying electricity from an electric vehicle to a building's existing electrical wiring. The company is now working to apply the V2H system to fuel cell buses which, with their tanks of stored hydrogen, can supply a much greater amount of electrical power. The goal is to use a fuel cell bus to provide a maximum output of 9.8 kW for 50 hours.  With a full tank of hydrogen, a fuel cell bus with the V2H system could be used to power the lights inside an average school gymnasium (with a power consumption of approximately 100 kWh) for approximately five days.

TMC plans to test this V2H system for fuel cell buses in FY2013 and FY2014 as part of the Toyota City Low-Carbon Verification Project, which has been adopted as one of the Next-Generation Energy and Social System Demonstration Projects being promoted by the Ministry of Economy, Trade and Industry.
