Wiring up the car

Electrical System, Featured

A lot of wires are necessary to make an electric car operate – we need to connect the battery, motor controller, motor, solar panels, MPPTs (Maximum Power Point Trackers, which are used to optimize power output of the solar panels), shutoff switches, relays, and more! To safely wire everything up, we first created a detailed […]

An integral part of dealing with lithium ion batteries is having a battery management system (BMS). The purpose of this is to balance the cells (or sets of cells) in series to ensure while charging/de-charging the load is consistent across the whole battery. We are using a BMS which includes an android app to monitor […]
