[0078] 101, obtaining an actual current value and / or an actual power value in a battery system; wherein the actual current value includes a first actual continuous pulse output capability and a first actual short-time pulse output capability, and the actual power value includes a second actual continuous pulse output capability and a second actual short-time pulse output capability.

[0079] Exemplarily, the execution subject of the embodiment can be an electronic device, or a terminal device, or a battery system overload detection device or equipment, or other devices or equipment that can execute the embodiment, which is not limited. In the embodiment, the execution subject is introduced as an electronic device.

[0080] First, an actual current value and / or an actual power value in a battery system need to be obtained. The battery system includes a battery and a plurality of electrical components, including copper bars, wire harnesses, board cards, sensors, etc. The electronic device can obtain the actual current value and / or the actual power value in the battery system, wherein the actual current value includes a first actual continuous pulse output capability and a first actual short-time pulse output capability, and the actual power value includes a second actual continuous pulse output capability and a second actual short-time pulse output capability.

[0081] 102, determining a first time period of the first actual continuous pulse output capability, a second time period of the first actual short-time pulse output capability, a third time period of the second actual continuous pulse output capability, a fourth time period of the second actual short-time pulse output capability, and environmental information of the battery system.

[0082] ​Exemplarily, the electronic device acquires a first time period of a first actual continuous pulse output capability of the battery system, a second time period of a first actual short-time pulse output capability, a third time period of a second actual continuous pulse output capability, a fourth time period of a second actual short-time pulse output capability, and environmental information of the battery system, wherein the environmental information includes a temperature value, a voltage value, and a system on chip (SoC).

[0083] 103. According to the first time period, the second time period, the third time period, the fourth time period, and the environmental information, determine a standard current value corresponding to the actual current value, and a standard power value corresponding to the actual power value; wherein the standard current value includes a first standard continuous pulse value and a first standard short-time pulse value, and the standard power value includes a second standard continuous pulse value and a second standard short-time pulse value.

[0084] Exemplarily, the standard current value and the standard power value are values determined by the electronic device in advance. Specifically, the electronic device acquires a first output capability of the battery in the battery system corresponding to each environmental information and each time period, and acquires a second output capability of the electrical component in the battery system corresponding to each environmental information and each time period, wherein the first output capability includes a first current value and a first power value output by the battery, the first current value includes a first continuous pulse output capability and a first short-time pulse output capability, the first power value includes a second continuous pulse output capability and a second short-time pulse output capability, the second output capability includes a second current value and a second power value output by the electrical component, the second current value includes a third continuous pulse output capability and a third short-time pulse output capability, and the second power value includes a fourth continuous pulse output capability and a fourth short-time pulse output capability.

[0085] Then, the electronic device compares the first continuous pulse output capability and the third continuous pulse output capability corresponding to each environmental information and each time period to obtain the minimum continuous pulse output capability corresponding to the current value, and compares the first short-time pulse output capability and the third short-time pulse output capability corresponding to each environmental information and each time period to obtain the minimum short-time pulse output capability corresponding to the current value.

[0086] Finally, according to the minimum continuous pulse output capability corresponding to the current value, the preset sampling accuracy, and a coefficient not greater than 1 multiplied by the minimum current value of the battery system, a first standard continuous pulse value corresponding to each environmental information and each time period is generated. According to the minimum short-time pulse output capability corresponding to the current value, the preset sampling accuracy, and a coefficient not greater than 1 multiplied by the minimum current value of the battery system, a first standard short-time pulse value corresponding to each environmental information and each time period is generated. According to the minimum continuous pulse output capability corresponding to the power value, the preset sampling accuracy, and a coefficient not greater than 1 multiplied by the minimum power value of the battery system, a second standard continuous pulse value corresponding to each environmental information and each time period is generated. According to the minimum short-time pulse output capability corresponding to the power value, the preset sampling accuracy, and a coefficient not greater than 1 multiplied by the minimum power value of the battery system, a second standard short-time pulse value corresponding to each environmental information and each time period is generated. According to the first standard continuous pulse value corresponding to each environmental information and each time period, a mapping relationship between the time period of the current value, the environmental information, and the first standard continuous pulse value is generated and stored. According to the first standard short-time pulse value corresponding to each environmental information and each time period, a mapping relationship between the time period of the current value, the environmental information, and the first standard short-time pulse value is generated and stored. According to the second standard continuous pulse value corresponding to each environmental information and each time period, a mapping relationship between the time period of the power value, the environmental information, and the second standard continuous pulse value is generated and stored. According to the second standard short-time pulse value corresponding to each environmental information and each time period, a mapping relationship between the time period of the power value, the environmental information, and the second standard short-time pulse value is generated and stored.

[0087] Therefore, the electronic device can determine the first standard continuous pulse value of the battery system corresponding to both the first time period and the environmental information in which the battery system is located according to the mapping relationship between the time period of the preset current value, the environmental information, and the first standard continuous pulse value. The first standard short-time pulse value of the battery system corresponding to both the second time period and the environmental information in which the battery system is located is determined according to the mapping relationship between the time period of the preset current value, the environmental information, and the first standard short-time pulse value. The second standard continuous pulse value of the battery system corresponding to both the third time period and the environmental information in which the battery system is located is determined according to the mapping relationship between the time period of the preset power value, the environmental information, and the second standard continuous pulse value. The second standard short-time pulse value of the battery system corresponding to both the fourth time period and the environmental information in which the battery system is located is determined according to the mapping relationship between the time period of the preset power value, the environmental information, and the second standard short-time pulse value.

[0088] 104. If it is determined that the actual current value is greater than the standard current value, and / or the actual power value is greater than the standard power value, an overcurrent protection signal and / or an overpower protection signal is generated and executed.

[0089] For example, the electronic device generates and executes an overcurrent protection signal if it is determined that the first actual sustained pulse output capability in the actual current value is greater than the first standard sustained pulse value, and / or the first actual short-time pulse output capability in the actual current value is greater than the first standard short-time pulse value; and / or, the second actual sustained pulse output capability in the actual power value is greater than the second standard sustained pulse value, and / or the second actual short-time pulse output capability in the actual power value is greater than the second standard short-time pulse value. The protection actions corresponding to the overcurrent protection signal and / or the overpower protection signal include cutting off a relay, requesting to report a limited current / power, etc., thereby avoiding damage to the battery system.

If it is determined that the actual current value is greater than the standard current value, and / or the actual power value is greater than the standard power value, the overcurrent protection signal and / or the overpower protection signal are generated and executed. In the scheme, the first standard continuous pulse value and the first standard short-time pulse value corresponding to the actual current value are determined, and the second standard continuous pulse value and the second standard short-time pulse value corresponding to the actual power value are determined according to the first time period, the second time period, the third time period, the fourth time period, and the environmental information.

[0126] For example, the overload protection scheme in the method can be cutting off a relay, or can be requesting to limit the reported current / power. Generally, if the current / power input by the power supply (charging pile, PCS, etc.) to the battery system exceeds the actual capability, it often means that the current / power input by the power supply to the battery system exceeds the reported current / power value. The possible reasons are: the control capability of the power supply on the current / power is insufficient; the communication between the power supply and the battery system is not timely and effective; the power supply does not respond to the current / power reporting request of the battery system. In this case, the battery system requests to limit the reported current / power, which may be ineffective, and the protection action can be selected as cutting off the relay. For some application scenarios and products, the situation may be different. Therefore, the protection action can also be selected as the battery system requesting to limit the reported current / power when the overload is triggered.
