Battery Management Systems

High performance battery packs are typically constructed using lithium ion cell chemistries. However, they require continuous monitoring to ensure that voltages and temperatures are maintained within required limits. The Dilithium BMS products provide these features and more.

The Master Control Unit (MCU) includes BMS, charger and display controllers all integrated in one unit. It requires BMS Satellites for cell measurement, facilitating a flexible distributed pack solution. The MCU has dual canbus networks for charger and accessory control, and handles satellites for packs with up to 288 cells. Click on the link below to see all the features of this powerful device. 

The BMS Controller (BMSC) contains an internal measurement board for up to 24 cells. It can control up to 3 external satellites for a total of 96 cells. It has a single canbus network and requires an external charge controller (our EVCC). 

These are 12 Volt Systems! Battery Management Systems are powered by a 12 Volt supply. Do Not connect these components to motor controller key switch circuits, because they may provide full pack voltage, which would destroy the BMS. Check voltage before connecting.
