Description

A battery switching device based on remaining power Technical Field

[0001] The present invention relates to the technical field of battery switching, and in particular to a battery switching device based on remaining power. Background Art

[0002] A battery is a device that can convert chemical energy into electrical energy. It contains an electrolyte solution and metal electrodes to generate an electric current. It is a cup, tank, or other container, or part of a composite container. It has a positive electrode and a negative electrode. With the advancement of technology, batteries generally refer to small devices that can generate electrical energy. Using batteries as an energy source can produce a current with stable voltage, stable current, long-term stable power supply, and little external influence. Batteries are simple in structure, easy to carry, and easy to charge and discharge. They are not affected by external climate and temperature, and have stable and reliable performance. They play a significant role in all aspects of modern life. Battery switching equipment is designed to ensure the normal operation of the system. When the main power supply is suddenly interrupted, it can automatically switch to the backup power supply through the circuit.

[0003] A Chinese patent with authorization publication number CN214799017U discloses a terminal device including an automatically switching backup battery, including a terminal body, a battery cavity for installing a main battery, a battery cover on the battery cavity, and a small battery connected to the terminal body. The main battery and the small battery alternately power the terminal body. A switching device is provided on the terminal body or the battery cover, which can control the terminal body to enter a low-power state and switch from main battery power supply to small battery power supply. That is, before replacing the battery, the switching device is triggered to make the terminal body enter a low-power state and switch from main battery power supply to small battery power supply. The main battery can be taken out and replaced, so that the terminal does not need to be shut down or restarted when the battery is replaced, saving time.

[0004] The above-mentioned battery switching device has a single function and is usually used as a backup power supply switch, but it does not have the function of detecting the power level of the two batteries. As a result, the battery power is easily exhausted during use, causing serious damage to the battery life.

[0005] Usually, when charging the battery, the use of the device needs to be interrupted, and the charging time is generally long, which affects the use of the device and causes unreasonable charging time.
