Battery Management Systems
EV Parts Battery Management System
With over 15 years of BMS development experience, we offer a proven track record in Battery Management Systems across a wide range of diverse industries and applications. Our extensive range of modular BMS solutions is designed to fit a wide spectrum of needs, including:
-
- Motorsports
- Marine
- Hybrid Gensets
- Static Energy Storage
- Off-Highway Vehicles
Key Features:
- Scalable Distributed Architecture: Our BMS can easily scale to manage systems ranging from 24V up to 1kV.
- Non-Parasitic Design: This essential feature extends the shelf life of your batteries by ensuring no capacity is drained while the system is inactive.
Cell Interface Modules
Our EV Parts Cell Interface (CI) modules form the essential core of any Battery Management System. Their primary function is to meticulously monitor the voltage and temperature of every cell within the battery pack, providing the BMS Controller with precise, real-time internal data. Additionally, these modules incorporate fully independent cell balancing capabilities, actively ensuring that all cells in the pack maintain optimal balance.
8 Cell Interface – CI8
The CI8 is our most mature product, it has a track record of over 15 years of usage in many applications. The CI8 is housed in an aluminium chassis and encapsulated in thermally conductive potting to ensure the PCB is protected and that heat from balancing the cells can be efficiently dissipated.
Features:
- Monitors up to 8 Cell voltages and 2 temperature sensors
- 2kV working Isolation
- 5kV withstand Isolation
- 800mA passive balance current per cell
- CAN communication
- 12V or 24V optional
- Zero parasitic drain from cells during operation or storage
12 Cell Interface – CI12
The CI12 is our upgraded version of the CI8, expanded to work with 12 cells, it is a great alternative to the CI8 and can be supplied with either waterproof connectors in a potted chassis for extreme environments, or as a conformally coated PCB with right angle connectors to suit applications where space is limited.
Features:
- Monitors up to 12 Cell voltages and 6 temperature sensors
- 2kV working Isolation
