Electrical Progress Report: March 2019

The electrical team has seen tremendous progress in areas of the high voltage system, including battery management system (BMS), the batteries themselves, and the charging mechanism for Renatus. We have successfully connected and programmed the battery management system along with optimizing its capabilities for our own designed battery pack. Wiring instructions for implementing it into the car have been completed, along with verification that all the battery cells are at their optimal storage voltage. The electrical and programming team have also successfully interfaced the BMS with the controller area network bus (CANBUS) network of the central processing unit of the car. With this communication network we are able to collect data from the BMS and have a real time battery monitoring driver interface within the car. More recently the electrical team has looked into many possible charging solutions for the batteries including multiple low voltage chargers, one very high voltage charger, and designing a charger from scratch to interface with the BMS better. On to news about the future car, the electrical team has begun to outline some design considerations they want to include in the car. As well as outlining the design criteria, aka things that the car needs to have in order to be successful. All in all the electrical team is making progress on the vital systems that will enable Renatus to perform exceptionally well.
