SmartGen产品 | 众智科技BMS电池管理系统全新介绍
BMS全称是Battery Management System，电池管理系统。它是配合监控储能电池状态的设备，主要是为了智能化管理及维护各个电池单元，监控电池的状态，防止电池出现过充电和过放电，从而延长电池的使用寿命。
BMS能够实时监控、采集储能电池的状态参数，并对相关状态参数进行必要的分析计算，得到更多的系统状态评估参数，并根据特定保护控制策略实现对储能电池本体的有效管控，保证整个电池储能单元的安全可靠运行。
同时BMS可以通过自身的通信接口、模拟量或数字量输入接口与外部其他设备（比如：PCS、EMS、消防系统等）进行通讯，确保电站安全、可靠、高效并网运行。
众智科技开发的BMS系统由HBCU100和HBMU100模块构成。
HBCU100模块通过对BMU上传电芯电压、温度的分析，完成对电芯的保护，以及SOC、SOH的计算等功能。
HBMU100模块用于电芯电压及温度采集以及对外数据上传。其中HBMU100-16可采集16个电芯电压及8个温度数据，HBMU100-32可采集32个电芯电压及16个温度数据。
系统通过采集电池模块数据，并上传至监控平台，通过三级故障保护系统以及对外置主回路继电器的控制，实现对电芯的过欠压、温度过高/过低、充放电过流等保护。
BMS可与多个厂家的储能变流器(PCS)实现协议兼容，管理电池组的充放电。可广泛应用于各种功率等级的储能电池柜。

SmartGen |BMS Products Introduction
BMS (Battery Management System)
BMS is the abbreviation of Battery Management System. It is a device to monitor the status of energy storage batteries, which is mainly used for intelligent management and maintenance of each battery unit to prevent over charge and over discharge, prolong the service life of the battery and monitor battery status.
BMS can monitor and collect the status parameters of energy storage battery in real time (including but not limited to single battery voltage, battery pole temperature, battery circuit current, terminal voltage of battery pack, insulation resistance of battery system, etc.), analyze and calculate the relevant status parameters, get more system status evaluation parameters, realize the effective control of energy storage battery body according to specific protection and control strategy, and ensure safe and reliable operation of whole battery energy storage unit.
Meanwhile BMS can communicate with external devices (PCS, EMS, fire protection system) through its communication port, analog/digital input/output ports, ensure the safe, reliable and high-effective grid connection and run of the power station.
BMS developed by SmartGen includes HBCU100 and HBMU100 two modules.
HBCU100 module completes the protection of battery cell and calculation of SOC, SOH through the analysis of battery cell voltage, temperature uploaded by BMU.
HBMU100 module is used for collecting cell voltage and temperature, and uploading external data. HNMU100-16 can collect 16 cell voltage and 8 temperature data, HBMU100-32 can collect 32 cell voltage and 16 temperature data.
The system realizes the protection of cell over/under voltage, over/under temperature, charging/discharging current through battery module data collecting and uploading to monitoring platform, three-level fault protection system and control of external main circuit relay.
BMS can realize protocol compatibility with energy storage converter (PCS) from multiple manufacturers to manage charging and discharging of battery pack. It can be widely used in energy storage battery cabinets of various power levels.
