Best regards, lho
Hi, I am working on the DC EV Charger Development Project. I am using a DC car simulator from Codico (Electro Vehicle (EV) Simulator 1.1) to develop the same. The details of the DC EV Simulator are as follows: Platform: SEVENSTAX V2G EV Simulator Firmware Version: i.e. V2G EV V01.01.04 Host Controller Interface: Ethernet / SPI
Right now, I am testing our DC EV charger for the charging cycle on Electro Vehicle (EV) Simulator 1.1 with OCPP 1.6, and I am facing an error.
The OCPP charging cycle started without any issues, but when I stopped the charging cycle through OCPP, I got the following error on the EV charger side. _2024-04-26 16:25:41.508270 [ERRO] iso15118_charge void dlog_func(dloglevelt, const char, int, const char, const char*,...) shutdown() failed: The transport endpoint is not connected.**
But when we repeated the same on the real car, the charging cycle stopped without error. So this error is observed only on the EV simulator.
For detailed information please refer to the following log for communication between our DC EV charger and CODICO EV simulator
