Product Highlights
Intelligent Controls
4 independent outputs (braking, automated parking, door unlocking and calling for roadside assisstance), with different control strategies based on collision or power failure
Extended Service Life
Ultra long lifespan design, Cycle Life ≥ 8000 cycles, which is about twice as much as mainstream products. It ensures customer's product life, reduces annual usage costs, significant total life cycle cost advantage compared to traditional lead-acid batteries
Mature BMS Platform
High-precision sampling, hardware coulometer, OCV and EKF calibration ensure SOC accuracy MOSFET instead of traditional fuse, millisecond fault response capability
Tailored to Your Requirements
We can customize the structure, battery cell, BMS and other system solutions according to the actual needs of customers.
