Building high voltage automotive battery management systems

October 12, 2023

To ensure safety, performance and accuracy over the full system lifetime, it is essential to choose the right BMS components.

This can also maximize the range and lifetime obtainable from the Li-ion battery, which is a vital differentiator for carmakers.

The paper gives a general introduction to Li-ion batteries and BMS, before presenting Infineon’s products and system approach towards offering a best-in-class BMS by addressing the four key criteria:

Performance: reflecting the driving range per battery chargeBattery lifetime: reflecting the battery yearly depreciationSafety: protecting the battery from critical events, that might risk the safety of the passengersTotal system cost: reflecting the initial cost of the hybrid or electric vehicle
