The fault battery information is more detailed, the fault content is more intuitively presented, and the fault reason and the fault position can be determined through the target fault information and the fault battery information in the target fault content.
Therefore, the fault code of the battery system is obtained, and the fault code is retrieved to determine target fault information; acquiring fault battery information corresponding to the target fault information; and outputting target fault content based on the target fault information and the fault battery information. Therefore, the corresponding fault battery information is directly obtained by using the target fault information, so that the fault battery information is not required to be read from the data stream function manually, reading errors are avoided, and the complexity of operation is reduced; because the fault battery information is included in the target fault content, the fault content can be more intuitive, thereby improving the efficiency of battery maintenance.
Referring to fig. 2, an embodiment of the present application discloses a specific battery fault diagnosis method applied to a diagnosis device, where the method includes:
step S21: acquiring a fault code of a battery system, and searching whether preset fault type information and preset fault degree information exist in the fault code so as to determine the existing target fault information comprising target fault type information and target fault degree information.

For example, when the preset fault type information is voltage and temperature, and the preset fault degree information is high and low, the retrieval process is as follows: and sequentially searching whether characters representing voltage, temperature, low and high exist in the fault code to determine the existing target fault type information (voltage or temperature) and target fault degree information (low or high). For example, if a character indicating temperature and high is searched and a character indicating voltage and low is not searched, the target failure type information is temperature, the target failure degree information is high, and the target failure information is temperature high.

Note that the target failure information is determined using the above-described flag indicating that it is retrieved or not retrieved, and for example, when V ═ 1, T ═ 0, L ═ 0, and H ═ 1 are recorded, it is determined that the target failure information is high in voltage.
Step S22: judging whether fault battery information which comprises a target numerical value and a target battery identification corresponding to the target numerical value and corresponds to the target fault information can be directly obtained through a battery management system; wherein the target numerical value corresponds to the target failure type information and the target failure degree information.

It should be noted that the target value and the target battery identifier corresponding to the target value may be recorded locally when the target value and the target battery identifier corresponding to the target value are obtained, and in addition, the battery may be a single battery.
It should be noted that, when the preset fault type information is voltage and temperature, and the preset fault degree information is high and low, if a target value corresponding to a battery and a corresponding target battery identifier can be directly obtained from the battery management system, where the target value is one of a highest voltage value, a lowest voltage value, a highest temperature value and a lowest temperature value, and if the target value is the highest voltage value, a first instruction is sent to the battery management system to obtain the highest voltage value corresponding to the battery and the corresponding target battery identifier, which are returned by the battery management system based on the first instruction; if the target value corresponding to the battery and the corresponding target battery identifier cannot be directly obtained from the battery management system, and if the target value is the highest voltage value, sending a second instruction to the battery management system, obtaining the voltage value of each battery and the corresponding original battery identifier which are sequentially returned by the battery management system based on the second instruction, then selecting the highest voltage value from the voltage values, and determining the target battery identifier corresponding to the highest voltage value to obtain fault battery information comprising the highest voltage value and the target battery identifier.
It should be noted that the battery identifier may be a battery number, the highest voltage value may be represented by HV, the lowest voltage value may be represented by LV, the highest temperature value may be represented by HT, the lowest temperature value may be represented by LT, the target battery identifier corresponding to the highest voltage value may be represented by HVN, the target battery identifier corresponding to the lowest voltage value may be represented by LVN, the target battery identifier corresponding to the highest temperature value may be represented by HTN, the target battery identifier corresponding to the lowest temperature value may be represented by LTN, the voltage values of all the batteries and the original battery identifiers may be represented by SV1, SV2, SV3, SV4 to SVn, and 1, 2, 3, 4, and n are battery numbers; the temperature values and the raw battery identifications of all batteries can be represented by ST1, ST2, ST3, ST4 to STn. It should be noted that the value of n is the same or different for different vehicle types.
Step S24: and outputting target fault content based on the target fault information and the fault battery information.
In the embodiment of the application, target fault content is output based on the target fault information, the fault battery information and a preset content template.
In the embodiment of the present application, if the battery is a single battery, when the target failure information is a high voltage, that is, V is 1 and H is 1, the target value in the failure battery information is HV, the target battery is identified as HVN, that is, the number of the target battery is HVN, then the target failure content is: the method mainly comprises the following steps that when the single battery has an overhigh voltage fault and the single battery with the HVN number has a high fault possibility, the single battery with the HVN number is mainly checked, wherein the voltage value of the single battery with the HVN number is as follows: HV. Accordingly, when the target fault information is a voltage low, that is, V is 1 and L is 1, the target fault content is: the single battery has a low voltage fault, the single battery LVN has a high fault possibility, and the single battery LVN is mainly examined, wherein the voltage value of the single battery LVN is as follows: LV; when the target fault information is that the temperature of the single battery is high, that is, T is 1 and H is 1, the target fault content is: the method mainly comprises the following steps that when the single battery has an overhigh temperature fault, the possibility of the fault of the HTN single battery is high, and the HTN single battery is mainly investigated, wherein the temperature value of the HTN single battery is as follows: HT; when the target fault information is that the temperature of the single battery is low, that is, T is 1 and L is 1, the target fault content is: if the temperature of the single battery is too low and the possibility of the fault of the LTN single battery is high, please focus on the examination of the LTN single battery, wherein the temperature value of the LTN single battery is as follows: LT.
Therefore, the method and the device for detecting the fault of the battery system acquire the fault code of the battery system, and retrieve whether the fault code has the preset fault type information and the preset fault degree information so as to determine the target fault information including the target fault type information and the target fault degree information; judging whether fault battery information which comprises a target numerical value and a target battery identification corresponding to the target numerical value and corresponds to the target fault information can be directly obtained through a battery management system; wherein the target numerical value corresponds to the target fault type information and the target fault degree information; acquiring fault battery information which corresponds to the target fault information and comprises the target numerical value and the target battery identification corresponding to the target numerical value from the battery management system based on a judgment result; and outputting target fault content based on the target fault information and the fault battery information. Therefore, the corresponding fault battery information is directly obtained by using the target fault information, so that the fault battery information is not required to be read from the data stream function manually, reading errors are avoided, and the complexity of operation is reduced; because the fault battery information is included in the target fault content, the fault content can be more intuitive, thereby improving the efficiency of battery maintenance.
Referring to fig. 3, a schematic diagram of a battery fault diagnosis method is shown, taking target fault information as high voltage as an example, first reading a voltage or temperature-related fault code of a single battery in a battery system, then retrieving the fault code, and sequentially determining whether the fault is a voltage, a temperature, a low fault and a high fault, for example, determining that the target fault information is high voltage; then judging whether the highest voltage value and the corresponding target battery number can be directly read from the battery management system or not; if the battery can be directly read, directly reading the highest voltage value and the corresponding target battery number from the battery management system; and if the voltage values of all the single batteries in the battery management system and the corresponding original battery numbers cannot be read directly, sequentially reading the voltage values of all the single batteries in the battery management system and the corresponding original battery numbers, and then acquiring the highest voltage value and the corresponding target battery numbers based on the read voltage values and the corresponding original battery numbers. And finally, outputting target fault content according to the target fault information, the highest voltage value and a corresponding target battery number, wherein the target battery number refers to the position of the fault. It should be noted that in the figure, if a voltage fault is attributed, V is 1, if a voltage fault is not attributed, V is 0, if a temperature fault is attributed, T is 1, if a temperature fault is attributed, T is 0, if a low fault is attributed, L is 1, if a low fault is attributed, L is 0, if a high fault is attributed, H is 1, and if a high fault is attributed, H is 0.
