摘要： A charging method for a secondary battery including a lithium-supplementing material. The method includes acquiring a first state of health of the secondary battery in response to the secondary battery being at a preset charging node, activating the lithium-supplementing material in response to the first state of health being less than or equal to a first threshold to supplement lithium for the secondary battery, performing a charging process on the secondary battery, determining a second state of health of the secondary battery based on a working parameter of the secondary battery in the charging process, and charging the secondary battery in response to the second state of health being greater than a second threshold.

摘要： A battery-operated electronic device, such as, e.g., a continuous glucose monitoring (CGM) transmitter, has a switch disconnect circuit that reduces battery discharge while the device is stored and/or in “shelf mode.” The device has two externally-accessible activation pads each configured to contact a same electrical conductor positioned in packaging for the device that causes the switch disconnect circuit to disconnect the battery from device electronics while the device is in the packaging. Upon removal of the device from the packaging, the two activation pads no longer contact the electrical conductor, causing the switch disconnect circuit to automatically connect the battery to the device electronics. Methods of reducing battery discharge in a battery-operated electronic device and other aspects are also described.

摘要： This application relates to the technical field of energy storage devices, and in particular, to a device, a battery pack, and a battery module. The battery module includes a battery cell and an insulation board. The insulation board includes a body portion and a first bulge. The first bulge includes a sidewall and a top wall that close in to form an accommodation cavity. At least a part of an electrode terminal is accommodated in the accommodation cavity, and the top wall covers a part of the electrode terminal, thereby reducing a risk of letting metal particles or other impurities enter a position between the battery cells, where the metal particles are generated during welding. This reduces difficulty of cleaning the battery module, and improves safety and reliability of the battery module.
