Early on in the month, the team designed and installed a buzzer system in the Datsun connected to the BMS that warns the driver when a cell drops below a specified voltage. This was part of the solution to the problem we faced in March at the Spring Thaw Event where the batteries overheated and reached almost unrecoverable low voltages. Since we lost a few batteries at the Spring Thaw Event, the team put 12 more batteries in the front of the Datsun, bringing the car’s voltage up to around 176 V, the highest it is allowed to be for competitions and the highest it’s ever been in any of our cars. During this time we also reshaped one of the bottom side panels on the Datsun that had gotten a little beat up in one of the autocross runs from last month. We also continued to charge the car in preparation for the Herald Miller Invitational.
In the middle of April, the team traveled to North Carolina to participate in the Herald Miller Invitational, a substitute event created in place of the EV Challenge. To read more about that, click this link: https://svgsev.wordpress.com/2016/04/16/the-herald-miller-invitational/.
Towards the end of April, the team charged the Datsun and worked on minor things while also planning events and meetings for the future. We plan on taking the Datsun to the Shenandoah Valley Governor’s School’s Award Picnic in May to show off our work to other students, parents, and members of the community.
