STMicroelectronics AEK-POW-BMS63EN Automotive Battery Management System (BMS) Evaluation Board is based on the L9963E transceiver, designed to operate in hybrid and fully electric vehicles. This evaluation board can handle from 1 to 31 Li-ion battery nodes. Each node manages 4 to 14 battery cells for a 48V to 800V voltage range. The AEK-POW-BMS63EN evaluation board provides an elaborate monitoring network to sense the current, voltage, and temperature of each cell. This sensing helps to elaborate the State Of Charge (SOC) of each cell and, thereby, the SOC of all battery packs. The nodes. Each node manages 4 to 14 battery cells for a 48V to 800V voltage range. The AEK-POW-BMS63EN evaluation board is used in E-mobility, home battery accumulators, and BMSs.
The AEK-POW-BMS63EN evaluation board works in centralized and dual-access ring daisy chain topologies. In the centralized daisy chain configuration, a series of BMS is connected to a Microcontroller Unit (MCU) board through a single transceiver connected to the AEK-POW-BMS63EN isolated ISOLport. The dual ring access configuration is achieved by adding another transceiver that makes the communication bidirectional. The secondary ring is used as a backup in case the primary ring fails. The AEK-POW-BMS63EN evaluation board is available in 100mm x 76mm dimensions and is included in the AutoDevKit ecosystem.
