Lithium NMC battery system MHEV

48 Vfor automotive applicationshigh-capacity

Overview
48V main power supply for hybrid fuel vehicles, designed to support 48V loads such as start‑stop systems and electric power‑assist functions. Engineered for automotive integration with IP67 protection and automotive safety levels.

Features

• High charge/discharge performance: supports high‑rate charge and discharge to meet rapid energy demands for start‑stop and torque assist scenarios.
• Long lifecycle: engineered for ≥ 8000 cycles to reduce total lifecycle cost compared with mainstream alternatives.
• Mature BMS platform: high‑precision sampling, hardware coulometer, OCV and EKF calibration for accurate SOC/SOH estimation; MOSFET‑based fault interruption for millisecond response; multi‑layer protections against overcharge, over‑discharge, over‑temperature and short circuit to prevent thermal runaway.
• Customizable: enclosure, cell configuration, BMS and system interfaces can be tailored to customer requirements.
