Battery Management Systems (BMS) A BMS is the intelligent component monitoring and managing any lithium-ion battery pack. Players also can distinguish themselves by offering reservations and top-notch charger hardware that communicates efficiently with a vehicle's battery-management system. Measuring the battery is a bit more tricky, not just because the Pi itself doesn't have any kind of analog circuity whatsoever (the "ADC" is simply a digital communication interface to an external one, and the audio out is actually PWM with a very simple R-C lowpass), but also because a LiPo's discharge curve is so flat. Battery Management System (BMS) Mercedes CEO Dieter Zetsche says, "The intelligence of the battery does not lie in the cell but in the complex battery system." This is reminiscent to computers in the 1970s that had big hardware but little software [1] The purpose of a BMS is to: Provide battery safety and longevity, a must-have for Li-ion.
