Abstract
We developed the AC electric vehicle charging station (EVC-J) and have produced the EVC-J in Japan in Sep. 2009. This product is compliant with IEC61851-1. The EVC-J is the first product, which has an attached supply cable and vehicle connector and allows both Mode1-EV* and Mode2-EV* to be charged (*Mode1 and Mode2 are defined in IEC61851-1.).
We modified EVC-J and contributed 4 items of the 2009 low carbon projects**. (** 10 items were adopted by the Ministry of Economy, Trade and Industry (METI) as the 2009 model program to demonstrate social system for a low carbon society.)
The modified EVC-J has additional functions, that is identification and communication, for value added services demonstration (e.g. Billing, Maintenance management). Based on the experience of EVC-J and modified EVC-J, we developed the AC electric vehicle charging station (EVC1) and have produced the EVC1 in Japan in Nov. 2010.
The main features of EVC1 are as follows:
1) EVC1 has an attached supply cable and vehicle connector, and can charge EV/PHV in Japan (As of May. '11).
2) EVC1 has a communication function to the maintenance server using the cellular network as its standard function. Charging records, EVC-1 status, error information and etc acquired by the communication function can be monitored and used for maintenance service.
3) Easy operation flow, VFD (Vacuum Fluorescent Display) and touch panel contribute to EVC1’s operability improvement.
In the summer of 2011, we plan to introduce EVC1-IC with IC card identification function for the billing service, which may be adopted in the future.
