LFP battery module

48 Vfor electric vehiclesfor automotive applications

Product overview
48V automotive backup power supply designed to support low-voltage safety loads in electric vehicles and electrified commercial platforms. Compact modular LFP design with natural cooling and IP67 ingress protection for harsh environments.

Key features

• Intelligent controls: Four independent outputs with electronic switching; fast isolation of safety loads in case of short circuit or overcurrent.
• Long life: Ultra-long cycle life ≥ 8000 cycles, approximately twice that of mainstream alternatives, reducing total lifecycle cost compared to lead-acid solutions.
• Mature BMS platform: High-precision sampling, hardware coulometry, OCV and EKF calibration for accurate SOC/SOH estimation; MOSFET-based protection for millisecond fault response.
• Customizable: Modular options for enclosure, cell capacity (5–13Ah), BMS functions and communication interfaces to meet customer requirements.
