LV Powernet Control Energy Booster
Bi-directional energy booster for 12 V or 48 V powernet stabilization. Applicable as emergency power supply to the LV powernet. It offers both active and passive 12 V variants, as well as an active 48 V option to adapt to diverse power network requirements. By delivering peak current and energy, it enables the downsizing or replacement of the 12 V battery, reducing HV DC/DC costs and especially beneficial in low-temperature environments.
Highlights
- Backup Power supply that enables Steer-by-wire and high autonomies architectures
- Active Voltage stabilization to reduce under- and overvoltage events
- Reduction of overall system costs
Advantages
- Backup power supply for emergency maneuvers
- Downsizing or replacement of 12 V battery by providing peak current and energy especially for low temperature areas down to -40 °C
- Reduces HV DC/DC peak power and therefore system costs
- Flexibility for different powernet needs with availability of 12 V active or passive and 48 V active variants
