Beschreibung
The STEVAL-BMS114 is a battery management system (BMS) evaluation board that can handle from 1 to 31 Li-ion battery nodes. Each battery node manages from 4 to 14 battery cells, for a voltage range between 48 V and 800 V.The board is based on the L99BM114, a multicell battery monitoring and balancing IC, used in transportation and industrial application.The main activity of the L99BM114 is monitoring cells and battery node status through stack voltage measurement, cell voltage measurement, temperature measurement, and coulomb counting. Measurement and diagnostic tasks can be executed either on demand or periodically, with a programmable cycle interval. Measurement data are available for an external microcontroller to perform charge balancing and to compute the state of charge (SOC) and the state of health (SOH).The main functions of a standard BMS are monitoring and protecting the battery pack.The monitoring function is related to the measurement of the battery current, voltage, and temperature. The protection function brings the system to a safety state in case of under or overvoltage and overheating.The STEVAL-BMS114 provides an elaborate monitoring network to sense the voltage, current, and temperature of each cell.The STEVAL-BMS114 can work in two different daisy chain topologies: single access and dual access ring.In a single access daisy chain configuration, a series of AFE is connected to an MCU board through a single transceiver connected to the STEVAL-BMS114 isolated ISOLport. The AFE are connected to each other through the isolated ISOH port.The MCU communicates with the STEVAL-BMS1T hosted L99BM1T transceiver through the SPI protocol. The transceiver converts these signals into ISO SPI signals to communicate with the BMS.The STEVAL-BMS1T allows converting SPI signals into isolated SPI signals, thus reducing the number of necessary wires from 4 to 2 and implementing differential communication for higher noise immunity.
