BYD BM3451 Series 3/4/5 Cell Battery Protectors Datasheet

Datasheet 28 pages · 777 KB · EN

The BM3451 is a highly integrated protection IC for 3‑, 4‑, and 5‑cell rechargeable battery packs. It continuously monitors cell voltage, charge/discharge current, and temperature to provide over‑charge, over‑discharge, discharge over‑current, short‑circuit, charge over‑current, and over‑temperature protections. Delay times for over‑charge, over‑discharge and discharge over‑current can be set with external capacitors, and an external bleeding function balances cell capacity.

Typical applications include power tools, electric bicycles and UPS backup batteries. The device supports extended‑chip configurations for protecting six‑cell or larger packs, and offers pin‑compatible packages (TSSOP28, TSSOP20) with dedicated pins for balance control, temperature sensing, and MOSFET drive signals.

BYD M Series DC Communication Power Supply Manual

User Manual 2 pages · 68 KB · ZH

The M series DC communication power supply is offered in two models, DPs48600 and DPs48300. The DPS48600 system cabinet uses a separable design with up to 12 rectifier modules, delivering a maximum output of 600 A, while the DPS48300 can accommodate up to 6 rectifier modules for a maximum output of 300 A. Both models support flexible battery configurations, allowing iron‑phosphate or lead‑acid batteries to be installed without extra space.

The monitoring module provides real‑time display of bus voltage, battery current, temperature, and protection status. It includes RS‑232 communication, over‑voltage/under‑voltage protection, and automatic fault isolation. Additional features such as high‑efficiency (up to 939 % efficiency) and high power density (23.5 W/in³) are highlighted for demanding environments. This manual is written in Chinese.
