序号 | 故障情况 Fault conditions | 排查原因及解决办法 Troubleshooting reasons and solutions |
1 | 按DC Start无法开机 Cannot boot by pressing DC Start | 1. 检查断路器是否合闸（请保持合闸） 1. Check if the circuit breaker is closed (please keep closing) 2. 检查电池侧是否接入（请正确接入） 2. Check if the battery side is connected (please access it correctly) 3. 开机时按钮是否保持按住到开机 3. Does the button keep holding down when booting? 4. 电池电压是否过低 4. Is the battery voltage too low? |
2 | 断路器无法合闸 The circuit breaker cannot be closed | 1. 断路器是否在TRIP状态(参考3.断路器状态)，如果是,请先分闸再合闸 1. Is the circuit breaker in the TRIP state (refer to 3. Circuit breaker status), if yes, please open and close again 2. 是否短路故障导致断路器无法合闸 2. Whether the short circuit fault causes the circuit breaker to fail to close 3. 断路器或操作机构故障（请更换操作机构或者断路器） 3. Circuit breaker or operating mechanism failure (please replace operating mechanism or circuit breaker) |
3 | 开机后无法充放电 Cannot charge and discharge after booting | 1. 通过LCD(如果有)或者LS_BMS_Monitor上位机软件检查系统自检状态是否通过。 1.Check whether the system self-test status passes through the LCD (if any) or the LS_BMS_Monitor PC software. 2. 如自检未通过，通过LCD或上位机软件查看详细自检状态进一步排查 2. If the self-test fails, check the detailed self-test status through the LCD or PC software for further troubleshooting. 3. 如果并机使用，检查总线电压与电池电压压差是否过大 3.

4 | 放电过程中断路器跳闸 Circuit breaker tripping during discharge | 开机时电压是否过低？ Is the voltage too low at startup? (1).开机自检时检测到欠压一级保护，CBMS仍会闭合主回路以允许对电池充电。如果在5分钟内检测到放电，则会直接断开断路器以保护电池(默认为5分钟，如客户有要求，可在出厂时由厂家设置。1~60分钟可设置) (1). Undervoltage protection is detected during the power-on self-test, and the CBMS will still close the main circuit to allow the battery to be charged. If the discharge is detected within 5 minutes, the circuit breaker will be disconnected directly to protect the battery (default is 5 minutes, if required by the customer, it can be set by the factory at the factory. 1~60 minutes can be set) (2).开机自检时未检测到欠压一级保护，但在5分钟内检测到欠压一级保护(电池虚电)，5分钟后会直接断开断路器以避免电池进一步过放。 (2). Under-voltage protection is not detected during power-on self-test, but under-voltage protection (battery virtual power) is detected within 5 minutes, and the circuit breaker is directly disconnected after 5 minutes to avoid further over-discharge of the battery. |
5 | 其它情况下断路器跳闸 Circuit breaker tripping in other cases | 1. 检查是否有短路，或者持续电流>=断路器额定值导致断路器热脱扣 1. Check for short circuit, or continuous current >= breaker rating causes circuit breaker thermal trip 2. 开机自检时检测到欠压一级保护，5分钟后仍然没有充电，会断开断路器 2. Undervoltage protection is detected during power-on self-test. After 5 minutes, there is still no charge, and the circuit breaker will be disconnected. 3. 接触器是否失效 3. Does the contactor fail? |

锂电池储能系统往往由几百甚至更多节电池串并联而成，电压往往有几百伏，在安装调试和使用期间，必须按相关安全规定做好安全防护措施，避免安全事故的发生。
Lithium battery energy storage system often consists of several hundred or more battery strings connected in parallel, the voltage tends to have a few hundred volts, during the installation and commissioning and use, safety regulations must be made according to relevant safety precautions to prevent accidents.
1)、储能系统内部有高压，非本公司或本公司授权的技术人员，严禁擅自打开机箱进行拆卸和维护，否则有触电的解除，同时失去保修权利。
There is high voltage inside the energy storage system, which is not technically authorized by our company or our company. It is forbidden to disassemble and maintain the chassis without authorization. Otherwise, there will be an electric shock and the warranty right will be lost
2)、严禁BMS中任何线头或者接插件搭接在电池正负极，否则可能会有短路的危险并损坏电路板。
It is strictly forbidden to connect any wire end or connectors in the BMS to the positive and negative poles of the battery, otherwise the risk of short circuit may be caused and the circuit board may be damaged.
3)、严禁靠近水源或火源，以免电池因短路或过热起火。
It is forbidden to approach the water source or fire source to avoid the battery from fire due to short circuit or overheating.
4)、触发二级保护后断路器由BMS控制断开后，必须将系统下电排除故障，并至少间隔1分钟以后方可重新上电开机，否则可能会导致断路器分励线圈热量来不及散发而损坏。
After the secondary protection is triggered, the circuit breaker is disconnected by the BMS. The system must be powered off to remove the fault, and the power can be turned on again after at least 1 minute. Otherwise, the circuit breaker shunt coil heat can not be dissipated and damaged.
5)、如需要由电池来冷启动UPS/PCS，必须先将UPS/PCS侧的电池开关闭合后再启动电池。如果先启动电池，再闭合UPS/PCS侧的电池开关，由于UPS/PCS侧直流侧一般具有大电容，闭合瞬间电容相当于短路，此时电池给电容充电的电流会远高于CBMS机器内部的接触器额定值，极易造成接触器触点出现烧蚀、粘连，接触器触点接触电阻增大发热烧毁或者触点无法断开从而触发二级保护。
If the battery needs to be used to cold start the UPS/PCS, the battery switch on the UPS/PCS side must be closed before starting the battery. If the battery is turned on first, then the battery switch on the UPS/PCS side is closed. Since the DC side of the UPS/PCS side generally has a large capacitance, the closing instantaneous capacitance is equivalent to a short circuit. At this time, the current charged by the battery to the capacitor is much higher than that inside the CBMS machine. Contactor rating, it is easy to cause ablation and adhesion of the contactor contacts, contactor contact resistance increases, heat is burned or the contacts can not be disconnected to trigger secondary protection.
1)、安装及调试人员所使用的工具须有绝缘防护。
tools for installation and commissioning personnel must be insulated.
2)、在安装调试及维护时必须戴绝缘橡胶手套，视情况穿戴护目镜、绝缘橡胶靴，尽可能避免安全事故的发生。
Insulation rubber gloves must be worn during the installation and maintenance. Wear goggles and insulating rubber boots as the case may be to avoid the possible safety accidents.
3)、安装调试及维护过程中产生的线头金属等如掉入电池间，请务必使用绝缘工具取出，不能将杂物留置。
Installation, commissioning and maintenance of the thread metal generated in the process, such as dropped into the battery, be sure to use an insulating tool to remove, you can not be lingering debris.
4)、需要维护时，必须将CBMS的主断路器断开，切断电池组与PCS直流总线的连接。
When maintenance is required, the main circuit breaker of the CBMS must be disconnected to cut off the connection of the battery pack to the PCS DC bus.
5)、根据项目需求的不同，电池管理系统的充放电电流和充放电电压等参数在初次安装调试时已设定，不得擅自更改参数，否则可能会缩短电池寿命，更严重的可能会对电池造成严重危害产生安全事故。
According to project requirements, parameters such as charge and discharge current and charge and discharge voltage of the battery management system have been set during initial installation and debugging. Parameters may not be changed without authorization. Otherwise, the battery life may be shortened, and more serious battery may be damaged Cause serious harm to safety accidents.
6)、如遇储能柜周围起火，请务必使用干粉灭火器或者消防沙进行灭火。若使用液体灭火可能导致电击。
In case of fire around the energy storage cabinet, be sure to use dry powder fire extinguishers or fire extinguishing sand. Fire extinguishing with liquid may cause electric shock.
7)、如长期不使用系统，请务必断开电池柜的主断路器。
If the system is not used for a long time, be sure to disconnect the main circuit breaker of the battery cabinet.
8)、尽量避免长期在下列工作环境中使用：
try to avoid long-term use in the following working environment:
◎ 超过规格书规定的温度或湿度范围的场所
