ENNOID - BMS
ENNOID-BMS is an open-source configurable battery management system consisting of a Master board based on an STM32 microcontroller connected through an ISOSPI interface to several modular slave boards. ENNOID-BMS can monitor the specifics temperatures, currents & voltages that are critical for any lithium-ion battery packs. Based on the monitored inputs & the configured parameters, the master board can allow or interrupt the flow of energy from the battery pack by switching the state of external heavy-duty contactors. ENNOID-BMS can measure each cell voltage level & can trigger the passive balancing function during charging for cells above the configured limit to ensure that all cells have a similar State-Of-Charge (SOC). Parameters can be configured through the ENNOID-BMS-Tool software running on a USB connected host computer.
