Battery management system

Battery management system (BMS)

The 'pack is The most expensive single component in an EV and The contains detailed monitoring and control to maintain a long, safe operating life. The BMS is responsible for monitoring individual cell health, balancing, operating pack heating and cooling systems, reporting The state of charge and disconnecting The power from The vehicle in a fault or a collision.

This monitoring must continue even when the vehicle itself is parked and not in use. So that, for example, the pack heater can be engaged to maintain acceptable temperature in very cold the conditions. This top service energy efficiency and minimizing the load on the HV 'critical to minimize the range loss or worst case to prevent a dead vehicle.

PI 's reinforced isolated flyback and non - isolated buck converter products are idea for generating internal low voltage supply rails. The extremely low, The no - load consumption and high efficiency reduce background discharge of The HV'. The Overall power loss is lower than relying on The 12 V system and provides The BMS The ability to continue to operate on loss of The 12 V system (discharged 12 V ').
