Day 5 of the 2015 Bridgestone World Solar Challenge began more routinely the previous day. This day we were going to be driving on solar power, and would not be trailoring. We were able to start charging at sunrise, and then left promptly at 08:00. It was smooth driving until we had a few minor electrical issues around 11:00. We pulled over, and found the issue and were able to fix it in less than ten minutes. We then kept driving until the Coober Pedy control stop and arrived at 13:00. An hour later a new issue occurred. Some of the messages between the battery management system (BMS) were being lost. The battery management system monitors the batteries and makes sure they are operating safely. The car was missing a very small percentage of the messages from the BMS and the batteries were fine, but the car shut itself off just to be safe. After this happened twice we decided to pull over, and replace the cables between the main board and the BMS. This helped fix the problem. We then were able to keep driving until we made camp for the night. Our campsite ending up being 125km from any city.
