Severe failure:电池系统运行在其正常工作的极限范围之外，此时BMS立刻断开高压接触器与整车的电气连接并使高压接触器锁定在断路状态，无论任何命令都无法使高压接触器重新吸合，除非对BMS重新上电。 Indicates when one or more faults are active within the battery system and the highest severity level of all currently active faults. For each active fault the BCM shall determine the 17 / 30 - 18 - appropriate severity so as to protect the battery from damage or hazardous conditions. Faults shall start at the lowest severity possible; and then if conditions remain or continue to deteriorate, the severity level shall be increased to the next higher level until the highest level is reached. If a fault reaches or necessitates the highest severity level, the BCM shall open the main contactors immediately overriding the Main Contactor Control (0) command. The following is a description of the fault severity levels and how the HCM will react: • “Warning, no action” is the lowest severity level. The battery is operating in a degraded condition that does not require the main contactors to be opened, but is causing a reduction in available power. • “Imminent failure”. The battery is operating outside its normal operating limits and requires battery current to be ramped to zero. This severity level allows the HCM to control current to zero in a manner that provides smooth vehicle driveline transition. • “Urgent failure”. The battery is operating outside its normal operating limits and requires battery current to be ramped to zero within two seconds. This severity level forces the HCM to control current to zero without concern for vehicle driveline oscillations, but while maintaining vehicle stability and safety, within two seconds. If battery current does not achieve zero within two seconds, the BCM shall escalate the severity to the next highest level. • “Severe failure” is the highest severity level. The battery is operating outside its safe operating limits and requires the main contactors to be opened immediately. The BCM will open the main contactors on its own and the HCM will transition current to zero with in TBD seconds. The BCM shall latch the contactors open until the BCM has been shutdown. Signal Value Meaning Fault Severity Indicator 0 No fault active. 1 Warning, no action. 2 Reserved. 3 Reserved. 4 Imminent failure, vehicle ramps current to zero. 5 Urgent failure, vehicle ramps current to zero within two seconds. 6 Severe failure, BCM opens main contactors immediately. 7 Not available. 8.3.7 Isolation Resistance/绝缘电阻 指示电池组正极或电池组负极与24VGND的绝缘电阻，BMS上报绝缘电阻较低的数值。 Indicates the minimum isolation resistance between pack positive, pack negative, pack mid- point and chassis ground. Signal Scale Offset Unit Min Max Isolation Resistance 8 0 k? 0 2000 8.3.8 Message Counter/计数器 指示BCM处理器处于正确的工作状态，每个周期HCM都应对计数器的数值进行校验。 1、 如果该计数器的数值没有变化或者始终为Error状态，所有信号都应被判定为错误 数据。 18 / 30 - 19 - 2、 如果连续三帧或三帧以上CAN数据都是1状态，则HCM应将故障级别设定为 Imminent failure。 3、 如果2状态持续10秒钟，则HCM应将故障级别设定为Urgent failure。 4、 如果3状态持续2秒钟，则HCM应将故障级别设定为Severe failure。 电池系统正常运行状态计数器的值按0、1…7、0、1…7这种顺序循环变化。 当连续三帧计数器的值恢复到Counter Value范围之内则HCM应清除该故障。 A rolling message counter shall be used to monitor the integrity of the BCM processor. The receiving node shall check to ensure the counter value changes every cycle and that it is in the normal range. If the value does not change or is in the error range for one or more CAN frames, all signals from the sending node shall be considered in error. If the counter value does not change for three or more CAN frames, a message counter fault shall be set with severity “Imminent failure”. If the counter fault persists for ten seconds then the severity shall escalate to the next highest level “Urgent failure” for two seconds, after which the severity shall be “Severe failure” and the main contactors opened. If while the counter fault is active and battery operation drifts outside its normal operating limits, the appropriate fault and severity shall be set for the condition. Normal operation shall be resumed and the message counter fault cleared if the counter value changes and is in the normal range for three consecutive CAN frames. If the counter value is received as not available (0xF - all bits set to one), it shall be treated as a valid and changing counter value. Signal Value Meaning Message Counter 0 ~ 7 Counter Value 8 ~ 14 Error 15 Not Available 8.3.9 Message Checksum/消息校验和 指示BCM RAM处于正确的工作状态，HCM应对校验和进行校验。 1、 如果校验和校验错误则HCM应认为该数据包无效。 2、 如果1状态连续出现3次及3次以上则HCM应将故障级别设定为Imminent failure。 3、 如果2状态持续10秒钟，则HCM应将故障级别设定为Urgent failure。 4、 如果3状态持续2秒钟，则HCM应将故障级别设定为Severe failure。 当连续三帧计数器的值恢复到Counter Value范围之内则HCM应清除该故障。 校验和的算法为: Sum=Message Byte1+ Message Byte2+ Message Byte3+ Message Byte4+ Message Byte5+ Message Byte6+ Message Byte7+Message Rolling Counter+Sum of Message ID Bytes。 Message Checksum=((sum>>6)+(sum>>3)+sum)&0x07。 A message checksum shall be used to monitor the integrity of the BCM memory. The receiving node shall check to ensure the checksum value matches the checksum of the received message. If the checksum does not match for one or more CAN frames, all signals from the sending node shall be considered in error. If the checksum does not match for three or more CAN frames a message checksum fault shall be set with severity “Imminent failure”. If the checksum fault persists for ten seconds then the severity shall escalate to the next highest level “Urgent failure” for two seconds, after which the severity shall be “Severe failure” and the main contactors opened. 19 / 30 - 20 - If while the checksum fault is active and battery operation drifts outside its normal operating limits, the appropriate fault and severity shall be set for the condition.

The BCM shall indicate component failure or abnormal conditions through fault codes. 9.2 Diagnostic Trouble Codes/故障定位码 BCM将根据J1939-73中定义的DTC报告故障码。DTCs包括SPN、FMI、OC。 The BCM shall use Diagnostic Trouble Codes (DTC) to report fault code information as defined in the SAE J1939-73 specification. DTCs shall contain a Suspect Parameter Number (SPN) to indicate the item which has faulted, a Failure Mode Indicator (FMI) to indicate the fault conditions and an occurrence count (OC). The SPN Conversion Method shall always be set to zero. The OC shall be incremented when a particular fault SPN becomes active regardless of the FMI. Fault code time stamp data shall be accessible through data access parameters, refer to the DATA ACCESS section for details. 9.3 Fault Table/故障表 对于多个传感器决定一个故障码的情况，由最坏情况的测量值决定故障码。例如:电池 包中的任何一节电池的电压超过安全电压限制，Cell Over Voltage故障码将被置位。 In cases where more than one sensor or component exists to measure a characteristic, the fault for that characteristic should be determined by the worst case condition of all conditions measured. For example: The fault “Cell Over Voltage” would be set if any cell in the battery exceeds its safe operating voltage limit. When detecting out of range sensor failure the BCM shall, in addition to signal range, determine sensor drift due to temperature and set the appropriate fault if drift is excessive. If the sensor drifts high, then the out of range high fault shall be set. Likewise if the sensor drifts low, the out of range low fault shall be set. 名称 BCU DM1 PGN 0xfeca 优先级 6 源地址 0xf3 ID 0x18fecaf3 长度 8 bytes 刷新时间 100ms No Start Length parameter Range UnOffset Scale Note bit (Bit) it 1 0 8 0xFF 2 8 8 0xFF 27 / 30 - 28 - 3 16 8 DTC1_B1 4 24 8 DTC1_B2 5 32 8 DTC1_B3 6 40 8 DTC1_B4 7 48 8 0xFF 8 56 8 0xFF 说明: 1、 参考J1939规定进行DM1。 2、 同时有多个DTC时，1s内每次发送不同的DTC。超过10个DTC 时，只发送比较重要的10个。 3、 建议检查和发送的故障见故障列表章节。 Fault Description SPN FMI SEVERITY520294 0 6 Cell Over Votlage - Most Severe 严重过压 SeveritCell Over Voltage - Least Severe 最小过压 520294 15 1 y Cell Under Voltage - Most Severe 严重欠压 520294 1 6 Cell Under Voltage - Least Severe 最小欠压 520294 17 1 Cell Voltage Sensor Out of Range High 520294 3 4 Cell Voltage Sensor Out of Range Low 520294 4 4 Pre-contactor Battery Over Voltage - Most Severe 520295 0 6 Pre-contactor Battery Under Voltage - Most Severe 520295 1 6 Pre-contactor Battery Voltage Sensor Out of Range High 520295 3 1 Pre-contactor Battery Voltage Sensor Out of Range Low 520295 4 1 Post-contactor Battery Voltage Sensor Out of Range High 520296 3 1 Post-contactor Battery Voltage Sensor Out of Range Low 520296 4 1 28 / 30 - 29 - Cell Imbalance(电池压差) 520297 0 1 Cell Balance Circuit Fault 520298 11 1 Cell Over Temperature – Most Severe 520299 0 5 Cell Over Temperature – Moderately Severe 520299 16 1 Cell Over Temperature – Least Severe 520299 15 1 Cell Temperature Sensor Out of Range High 520300 3 4 Cell Temperature Sensor Out of Range Low 520300 4 4 Cell Temperature Delta 520300 1 1 Coolant Inlet Temperature Sensor Out of Range High 520301 3 1 Coolant Inlet Temperature Sensor Out of Range Low 520301 4 1 Isolation Under Resistance – Most Severe 520303 1 5 Isolation Under Resistance – Least Severe 520303 17 1 Isolation Resistance Sensor Fault 520303 11 1 Battery Over Current Charge 520304 3 5 Battery Over Current Discharge 520304 4 5 Fine Current Sensor Offset Excessive 520305 2 1 Fine Current Sensor Shorted High 520305 3 1 Fine Current Sensor Shorted Low 520305 4 1 Fine Current Sensor Open 520305 5 1 Coarse Current Sensor Offset Excessive 520306 2 1 Coarse Current Sensor Shorted High 520306 3 4 Coarse Current Sensor Shorted Low 520306 4 4 Coarse Current Sensor Open 520306 5 1 Microprocessor, RAM Check, ROM and EEPROM Checksum 520307 31 1 Communication Message Counter, Checksum, No Tx/Rx Fault 520308 2 5 Error Power Supply Over Voltage 520309 3 1 Power Supply Under Voltage 520309 4 1 Main Pre-charge Contactor Stuck Closed 520310 7 4 其他故障(总压过高、总压过低、SOC过低) 520452 2 Fault Description SPN FMI SEVERITY Main Pre-charge Contactor Short to High Source 520310 3 1 Main Pre-charge Contactor Short to Low Source 520310 4 1 Main Pre-charge Contactor Open Circuit 520310 5 4 Main Positive Contactor Stuck Closed 520311 7 5 Main Positive Contactor Short to High Source 520311 3 4 Main Positive Contactor Short to Low Source 520311 4 4 Main Positive Contactor Open Circuit 520311 5 4 Main Negative Contactor Stuck Closed 520312 7 5 Main Negative Contactor Short to High Source 520312 3 4 Main Negative Contactor Short to Low Source 520312 4 4 Main Negative Contactor Open Circuit 520312 5 4 Cell Controller Communications Fault 520315 9 5 Battery Pack General Failure 520316 12 4 Main Pre-charge Sequence Failure 520319 11 5 Main High-Voltage Interlock Loop Open Circuit 520448 5 6 Auxiliary High-Voltage Interlock Loop Open Circuit 520449 5 5 10 使用情况 2013年3月中通济南5台，采用此协议; 2013年6月中通集宁100台，采用此协议; 29 / 30 - 30 - 2013年6月中通濮阳40台，采用此协议; 2013年6月中通菏泽100台，采用此协议; 2013年6月中通济宁40台，采用此协议; 2013年6月中通晋中80台，采用此协议; 2013年7月青年样车1台，采用此协议; 30 / 30
