Description

Technical Field

[0001] The present invention relates to the technical field of battery charging, in particular to a battery charging device for a rechargeable battery. Background Art

[0002] Rechargeable batteries are batteries that can be used repeatedly and restored by recharging. They are widely used in various electronic devices such as mobile phones, laptops, power tools and electric vehicles. There are various types of rechargeable batteries. Nickel-cadmium batteries are one of the earliest rechargeable batteries. They have the advantages of low cost and tolerance to overcharging, but there is a memory effect, that is, the maximum capacity of the battery is reduced when it is fully charged again after partial discharge. Nickel-metal hydride batteries improve this problem and have higher energy density and longer service life, but the cost is relatively high. Lithium-ion batteries are currently the most popular type of rechargeable batteries, favored for their high energy density, long cycle life and low self-discharge rate. They have no memory effect, can be charged at any charge level, and are lightweight and small in size. Lithium-ion batteries are widely used in portable devices such as smartphones and laptops. Lithium-polymer batteries are similar to lithium-ion batteries, but use solid polymer electrolytes instead of liquid electrolytes, which makes them lighter, thinner and more flexible in shape. They are often used in devices with strict requirements on space and weight. The charging process of rechargeable batteries usually involves three stages: constant current charging, constant voltage charging and floating charging. In the constant current stage, the battery is charged at the maximum current until the voltage reaches a certain level; in the constant voltage stage, when using a rechargeable battery, care should be taken to avoid overcharging or discharging, which may shorten the battery life or damage the battery. In addition, different types and brands of batteries may have different charging requirements, so it is very important to follow the manufacturer's instructions for charging. With the development of technology, the performance of rechargeable batteries has been continuously improved, bringing great convenience to our lives.

[0003] In the existing devices for charging rechargeable batteries, it is impossible to detect the status of the battery well. Whether the rechargeable battery is over-discharged or over-charged, it will cause damage to the battery, which greatly affects the service life of the battery. Rechargeable batteries with the same appearance but different voltages cannot be charged in different categories, which affects the charging efficiency. The heat generated when the battery is charged is also a factor that endangers the battery life and causes fire. Summary of the invention
