Toyota Industries Corp announced that it is developing an electric car charging station composed of solar cells and storage batteries at Tokyo Motor Show 2009.
The electricity generated by the solar cells is first stored in storage batteries and, then, used to charge electric vehicles. Showa Shell Sekiyu KK and Nissan Motor Co Ltd also announced in August 2009 that they would jointly develop a similar system (See related article).
This time, Toyota Industries exhibited charging equipment to be used at a charging station. It has a communication function and can supply 100/200V electricity. Mobile networks and LANs are expected to be used to transmit the authentication information of users, the amount of charge and so forth to a data center.
The charging equipment is scheduled to be released in or after 2010 at a price of several hundred thousand yen. The company has been developing the charging equipment in collaboration with Nitto Kogyo Corp.
Furthermore, Toyota Industries showcased a prototyped battery charger to be mounted in a vehicle. It can convert AC current into DC current and boost voltage from 100/200V to 300/400V to charge the secondary batteries of plug-in hybrid vehicles, etc.
