For the nerds wondering how we built BESSIE – this video is for you.
BESSIE is a grid-connected energy storage system that we made using second-life Nissan Leaf batteries and Nuvation BMS™. The two-port system features a 15 kilowatt charger-inverter. AC power comes in from the wall and is used to charge BESSIE. The output port is wired to our electric vehicle charging post in the parking lot.
