Low-Voltage Bms - Nuvation Energy NUV300-BC-12 Product Manual

3.1. Low-Voltage BMS

The Low-Voltage BMS contains analog-to-digital measurement circuitry which reads cell voltage,
current, and temperature values. It also contains processing capability and software to support
decision making and allow it to operate as a stand-alone Nuvation Energy Low-Voltage BMS.
The Low-Voltage BMS is available in two variants:
1. The NUV300-BC-12 which can monitor up to 12 voltage channels
2. The NUV300-BC-16 which can monitor up to 16 voltage channels
The external interfaces to this module are:
▪
Cell voltage and temperature sense connector
