单体电池检测精度、SOC检测精度、单体电池间的均衡等问题一直以来都是电池管理上的难题，且一直没有得到的解决方案。而我公司研发设计的电池管理系统针对以上难题，特别是在准确估测锂电池组的荷电状态（简称SOC）、动态监测锂电池组的工作状态和单体电池间均衡的难题上花了近两年时间进行突破，公司的电池管理系统全部使用美国凌特（Linear）LTC6803（第三代电池管理检测芯片），加上我们对于电池管理的独特思路和创新算法，使得我们的产品对于单体电池电压监测精度达到0.25%，SOC精度达到小于5%。

Single battery detection precision, SOC detection precision and single battery

balance have always been the challenges in battery management, and by far no

satisfactory solution has been found. Battery management systems developed

and designed by perfectly target at the above problems and breakthroughs have

been achieved after two-year research especially on precise estimation of

lithium battery state of charge (SOC), dynamic monitoring of lithium battery

working conditions as well as single battery balance. Battery management

systems of Liyun universally adopt American Linear LTC6803 (3rd generation

battery management test chip). With our unique ideas and innovative algorithm

for battery management, voltage monitoring precision of our products on single

battery reaches 0.25% with the SOC precision of less than 5%.

此外，我司的电池管理系统还具备强大的通讯功能，RS232和RS485通讯接口可适应各种通讯需求，液晶显示屏可以根据客户需求显示电池电量以及各种参数和报警状态。PC客户端界面可对单节电池电压、均衡状态、电池寿命等电池状态进行实时监控，并且可以对各种参数和保护响应进行设置。

In addition, our battery management systems also enjoy powerful communication

functions. The communication interfaces of RS232 and RS485 meet all

communications demands and the liquid crystal display, in accordance with

customer demands, shows battery power, various parameters and alarm condition.

Real-time monitoring of single battery voltage, balanced state and battery

life, together with settings of parameters and protection response, can be

realized via PC client interface.

所以我司的BMS具有强大的功能开发潜力，可根据客户的各种需求开发各种功能、更改相应尺寸，例如:CAN通讯、蓝牙通讯、开发通信协议、开发SMbus、数据存储、远程监控、网络模块、各种液晶显示（触摸屏、彩屏、LED等）、光耦独立等。

Therefore Liyun`s BMS enjoys immense functional development potential.

Functional development and modification of sizes can be made in conformity

with customer demands, such as CAN communication, bluetooth communication,

communication protocol development, SMbus development, data storage, remote

monitoring, network module, kinds of liquid crystal display (touch screen, color

screen, and LED, etc) and optical coupling independence.
