Battery Management Systems
Genasun can supply scalable battery management systems (BMS) for any battery system. Our BMS consists of one or more GLD BMS master modules, coupled with one cell module per lithium cell or group of paralleled lithium cells. The GLD aggregates cell data and coordinates cell balancing. Outputs are provided to control contactors to perform protection functions. All battery data is available via RS-232 and other formats, making our BMS an excellent choice for logging and battery system development. In addition to our stock BMS system, We can customize our technology for cost savings in OEM applications. Please contact us for details.
Applications:
- Electric Vehicles
- Lead-Acid Replacement
- Hybrid and Plug-in Hybrid Cars
- Robotics
- Solar Cars (e.g. MIT SEVT)
- Power for Remote Monitoring
- Anything that needs to go faster, farther, higher, deeper, lighter, or longer

Example GLD Data Output
Cell voltage is reported in mV, and cell temperature in 10ths of a degree C. This data maybe logged on a computer running Hyperterminal, etc. or used directly by other system components.
