LFP rechargeable battery

rectangular12 Vfor electric vehicles

Product overview
12.8V LFP backup power supply designed to support 12V low-voltage safety loads in electric vehicles, providing uninterrupted power for braking, automated parking, door unlocking and roadside-assistance calls.

Key features

• Intelligent controls: Four independent outputs (braking, automated parking, door unlocking, roadside assistance) with control strategies adapted to collision events and power failures.
• Long life: Ultra-long lifespan architecture with cycle life ≥ 500,000 cycles to reduce total lifecycle cost and support long-term vehicle requirements.
• Mature CMS platform: High-precision sampling and proprietary algorithms for accurate resistance and capacitance estimation. MOSFET protection replaces traditional fuses for millisecond-level fault response.
• Customizable: Structural design, cell selection, BMS and system-level solutions can be customized to customer requirements.
