Recent developments in rechargeable battery technology allow wider use of electric propulsion in electric vehicles, electric motorcycles, boats etc. Most popular high performance batteries are based on Lithium chemistries. Such batteries require systems to keep them in the specified usage range while being used. A Battery Management System (BMS) is required for batteries that are sensitive to their usage conditions such as current, voltage and temperature. The Emus BMS is a product intended for use with LiIon, LiPO, LiFePO4 and other chemistries prismatic battery cells which operating voltages range is from 2V to 5V. The Emus BMS is a distributed type of digital BMS with a central Control Unit. It does the balancing of the cells by dissipating the excess energy of cells as heat which is often referred to as passive balancing.
