Stop Charging Issue with Electro Vehicle (EV) Simulator 1.1 (Codico) for DC EV Charger #413

Open Anita-mahale opened 1 month ago

Anita-mahale commented 1 month ago

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. 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(dloglevel_t, 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

Please kindly suggest.  Also, we are not sure how to upgrade the firmware of the Electro Vehicle (EV) Simulator 1.1.
