Description

Technical Field

[0001] The utility model relates to the field of batteries, and more specifically to an energy-saving battery module. Background Art

[0002] In daily life, laminated batteries are widely used, such as in electronic products such as multimeters, microphones and toy cars. For electronic circuits, due to the tight coupling between components, even if there is no output at the output end, a weak leakage current will be generated at the input end. Since the working time of such electronic products is much shorter than the idle time, from a long-term perspective, the accumulation of such leakage current will account for a considerable proportion of the total battery power, resulting in a significant reduction in the battery life. For this reason, in actual use, some users will reverse the positive and negative poles of the battery and place it in the battery box after using the electrical appliance, but this requires taking out the battery, which is very inconvenient. Most people find it troublesome and rarely do so, preferring to allow the leakage current to be wasted.

[0003] For example, our company's authorized patent number CN202221131898.2 discloses a power-off protection anti-leakage energy-saving battery, including a shell, a battery core, a positive electrode and a negative electrode. The shell is provided with a storage compartment inside, and a partition is provided in the storage compartment. The partition separates the storage compartment into a protection compartment and a battery compartment. The battery core is placed in the battery compartment, and a power-off protection block is provided in the protection compartment. The power-off protection block includes an insulating plate rotatably connected to the partition and a conductive block provided on the insulating plate and electrically connected to the battery core and the negative electrode. This application drives the conductive block on the insulating plate to electrically connect the negative electrode and the battery core on both sides through a dial block, so that the battery can be used normally. When the insulating plate is connected to the elastic conductive columns on both sides, the negative electrode and the battery core are electrically isolated, resulting in the complete isolation of the positive and negative electrodes of the battery, which cannot be used normally, thereby effectively preventing leakage and improving the service life of the battery.

[0004] After analysis, we found that although our company's existing technology can solve the problem of battery leakage when electrical appliances are not in use, it cannot deal with the leakage problem caused by internal moisture due to long-term storage of batteries. In response to this, we provide an energy-saving battery module. Utility Model Content
