Technology

Core Technology

Full-stack in-house R&D, from hardware circuits to charging algorithms

New-Generation Power Solution · 94% Efficiency

A new high-efficiency power solution replaces the previous second-generation devices, and dynamic dead-zone control replaces fixed dead-zone control, raising conversion efficiency from 92.8% to up to 94% with lower heat and reduced loss.

11-Fold Full-Chain Protection

Input-side undervoltage, overvoltage and capacitive-region protection; output-side overvoltage, overcurrent, short-circuit, reverse-polarity and over-temperature protection, with fault self-diagnosis and auto-locking.

32-Bit Cortex MCU

A 32-bit Cortex-M0 core on the secondary side delivers far greater processing speed and resources than typical 8-bit solutions, with stronger expansion capability.

Potting Across the Range

BX series uses semi-potting and CZ series full potting, integrating circuit and components into one solid body, greatly improving waterproofing, shock resistance and high-temperature tolerance.
