Features:
- Fully configurable for different types of batteries (voltage levels, capacity, protections levels and delays).
- Determination of a battery status:
- State of charge (SOC)
- Depth of discharge (DOD)
- State of health (SOH)
- Effective capacity
- Cell resistance
- Cell monitoring:
- Measuring every cell voltage
- Temperature control
- Current monitoring (bidirectional Hall-Effect sensor with supply voltage 5 volts)
- Battery protections:
- Overcurrent
- Undervoltage
- Overvoltage
- High temperature
- Low temperature
- Heater control
- Cooler control
- Cell balancing
- Interfaces:
- CAN (CANopen protocol to configure the system, interaction with an external equipment)
System controller configuring
The system can be configured via CAN bus using the ElectricDeviceMonitor software. A USB-CAN adapter is required to connect a PC to the controller.
