800V 500A High-Voltage battery management control unit for battery systems 144V – 800V, With CAN-Bus communication
- Communication: CAN-Bus (NMEA2000, SMA, custom on request)
- Humidity: Max. 95% (non-condensing)
- Operating temperature range: -20°C to + 50ºC
- Protection class: IP65
- Power connections: Anphenol Powerlok 500 series
- Max. HV current continuous: 500A
- M12 Connection
Power ConnectorsPower connectors enable the Master HV to easily connect a series of batteries. The Amphenol PowerLok connectors are robust and have an integrated HVIL (High Voltage Interlock Loop) to monitor the connection. The low contact resistance allows for current up to 500 A continuously.
|Monitoring and Control|
Critical parameters are monitored by the Master LV such as cell voltages and temperatures of each connected battery module. A set of limits is determined providing boundaries. Several boundaries are set for each of the monitored parameters. First a control boundary which controls chargers or loads. Second a warning limit and third a critical fail which opens the safety contactors interrupting the power path from the batteries to loads and chargers. A well integrated system never opens its safety contactors during normal operation.
| Diagnostic tool software|
Battery system diagnostics are important during commissioning, system testing, service, maintenance and trouble shooting. The diagnostic tools provide all the detailed information about the battery system. Main values, like voltage, current and State-Of-Charge, can be viewed and logged to a file. Moreover, detailed battery information can be shown such as cell voltages, all temperature sensor, firmware version etc. Besides this information also history values and stored events can be read from the Master. To create more flexibility, settings can be configured, for example CAN-Bus protocol selection or adding a function to a dedicated output.
