产品描述

APHEV-BMS-01-16-01

1 Introduction

The BMS module of 16 series adopts high precision analog front-end chip and

high performance 32 bits MCU, superior performance to extend battery life, and

ensure the batteries for safety.

2 Composition of System

Main features: high precision signal acquisition module，high precision SOC

estimation module, active energy transfer balance mode，the cell information

storage module, the cell protection module (overcharge protection, over

discharge protection, high and low temperature of cell protection), optional

LCD display module.

3 Package Information

The package is labeled with five descriptors

4 Features

Communication	CAN 2.0
Extension	RS485 extension other modules
Force Balance Mode Balancing switch to position “I”.	Balance when High - Low difference is above 10mV. Stop balancing when the delta is 10mV
Automatic Balance Mode (Default) switch position “0”	(i) Balancing is always on: Monomer battery differences over 60 mV starts automatic balancing to 60mV. (ii) Balance every 15 days, Balance when High - Low difference over 60mV. Stop balancing when the delta is 10mV or Day 15+1
BMS Module circuit protection	Balancing modes will be turned off when the module temperature reaches 65°C, Balancing will restart when the temperature is below 45°C
