[0004] In the prior art, there is no differentiated control of the discharge overcurrent protection and discharge overtemperature protection of the battery according to the connection status of the mobile device and the battery. Regardless of whether the battery used by the mobile device is connected to the mobile device or not, When both the discharge over-current protection function and the discharge over-temperature protection function of the battery are disabled, when the battery used by the mobile device is not connected to the mobile device, the discharge over-current protection function and the discharge over-temperature protection function of the battery are disabled. , which affects the performance of batteries used in mobile devices, resulting in damage to the battery chemical system. For example, the internal resistance of batteries used in mobile devices causes the temperature of the battery to rise, which has a serious impact on the service life of the battery. Even cause damage to batteries used in mobile devices

The embodiment of the invention provides a control method with protection function and a battery management system. The method comprises: detecting the connection state between the battery management system and a movable device; and starting or closing the protection function of the battery module where the battery management system is located according to the connection state between the battery management system and the movable device. According to the technical scheme provided by the embodiment of the invention, the battery module is protected according to the connection state between a battery management system and a movable device, the distinguishing processing of the battery module is realized in different connection states; and moreover, the battery module is protected in the condition without influencing the battery module to supply power for the movable device, and the problems are avoided that the battery module performance is decreased to influence the endurance of the movable device and the likely caused damaging.
Description
【Technical field】 [0001] The invention relates to the technical field of communication, in particular to a method for controlling protection functions and a battery management system. 【Background technique】 [0002] In recent years, with the development of science and technology, more and more devices are powered by batteries, and the demand for batteries of various devices is becoming more and more differentiated. For batteries used in mobile devices, conventional protection measures such as discharge overcurrent protection and discharge overtemperature protection will be set. However, for some mobile devices with strong autonomous operation, such as drones, aerial photography power supplies, electric vehicles, etc., In normal use, if you turn on conventional protection methods such as discharge over-current protection and discharge over-temperature protection, it is likely to cause a power outage of the battery, which will cause heavy losses or even casualties. Therefore, ...
