In MR02EV I use a battery management system from Batrium which includes:
When charging the system ensures cells do not go over voltage by applying a variable bypass and/or throttling the charger output. It can also ensue cell-to-cell balancing is optimum.
When discharging the system is passive but will alarm when cells get to hot, or low voltage.
I have a Degree in Electrical Engineering from the University of Technology Sydney and am employed in Broadcast Television Industry. My hobby is the (continuing) modification of MR02EV. I am also the National Treasurer of the Australian Electric Vehicle Association.
