12V BMS

Hardware Features

  • ハイパワー対応

    Delivering 200A continuously at 65°C ambient thanks to high performing MOSFET technology, which also supports crank pulses and short circuit currents of over 1400A for 1s.
    Integrated dual bank circuit breaker concept allows diagnosis of circuit breaker operation and faults without interrupting supply of quiescent power to the vehicle Powernet.

  • Advanced battery protection

    The battery is protected from safety hazards at all times including the sleep mode.
    A dedicated short circuit protection safeguards against common short faults across the terminals.
    Reverse polarity protection ensures robustness against accidently mixing the terminals during jump start event.

  • 正確な電流測定

    Allows for accurate current measurement across a wide range of current and temperature. This includes accurate quiescent current monitoring during sleep mode.

  • Highly optimised reliable design

    Design optimised for cost, high volume manufacturing and 15-year in service requirements.
    Self-current consumption of 250uA when the vehicle is parked, meeting strict targets for applications without wake-up to charge feature.

  • Best in-class chipset

    Powered by Aurix TC365 – providing required performance, safety and connectivity (LIN of CAN FD) features.

12V BMS

ソフトウェアの特徴

  • Advanced state estimation and balancing

    Accurately estimates the State of Charge and State of Health of the battery, supporting both LFP and NMC chemistries.
    It also ensures all battery cells remain well balanced.

  • Power pulse prediction

    Provides accurate information about battery’s ability to provide power to complete a specific ‘mission profile’, e.g. automated driving or parking, in case of failure of the main power source, e.g. DCDC converter.

  • Battery protection

    Ensures the battery is always protected from all safety hazards in all operating modes.
    It controls circuit breakers independently in charging and discharging direction including highly robust diagnostics of all possible failures.

  • Monitoring quiescent current

    パワーネットの静止電流を監視し、バッテリーの過剰な消耗につながる可能性のある異常があれば、車両のエネルギー管理システムに通知する。

  • Service and maintenance support

    The BMS records key field usage and diagnostics data for offline analysis.
    It supports over-the-air software update with A/B image swap concept.

1

Book a Call

Let us understand your specific requirements to determine the fit of our 12V BMS platform solution.

2

Initial Evaluation

We will help you integrate our 12V BMS platform into your battery and calibrate it to your specific cell, so you can carry out necessary evaluation. If needed the mechanical concept can be adjusted at this stage.

3

Production Development

We will carry out all the necessary HW and SW modifications to meet all of our requirements, and mature the design for you through the DV, PV and PPAP stages. Before going into production, the 12V BMS will be assessed in accordance to ASPICE and ISO26262.

4

Field Updates

Post-production we can continue to support you with software improvements OTA.
