Our BMS is built on the experience accumulated at AVL over more than 15 years of battery development. The system is being developed continuously, and the fourth generation is now available. The next upgrade will provide additional core functions with even more precise predictive models.
State of Charge (SOC):
- Increased accuracy for lithium ferro-phosphate (LFP) batteries
- Non-linear dynamic modeling
- Optimal experiment design to reduce testing and calibration effort
State of Health (SOH):
- Implementation of a model to predict aging and durability
- Combination of SOH monitoring and durability prediction to increase precision and robustness
State of Function (SOF):
- Continuous calculation of current functional state
- Optimization of operational strategy to reach target durability, for example
- Adjustment of SOF based on predicted durability and SOH estimations
Hardware (control unit and module controller):
- Battery control unit with integrated high-voltage measurement and contactor control
- Module controllers for up to 18 cells in series with a board footprint of 70 x 90 mm
- Complete hardware and software implementation for ISO26262
- For batteries up to 1000V and subpacks with parallel processing
Modular system offering
By choosing our BMS, you are opting for a modular system. This helps you to add value and profitability to the battery, optimize the charging strategy, and increase workshop efficiency. You also enable cost-efficient battery replacement and reduce the total cost of ownership.
Virtual battery development tools
Our many years of expertise with simulations and the associated tools guarantee an efficient development process. You benefit from clear frontloading of tasks, with rapid validation at an early stage.
Embedding cells is pivotal in preventing battery aging. And a high-performance battery management system is key. This enables the dynamic load limits to be shifted, depending on the operational aging risk. Our tools are able to simulate most of these factors, allowing us to predict them virtually and take them into account in the development process.
