Description

Technical Field

[0001] The present invention relates to the field of automobile charging, and in particular to an overcharging prevention device for charging equipment of a new energy automobile. Background Art

[0002] Charging is a Chinese term that refers to the process of replenishing the charge of a device such as a battery. The principle is to pass direct current (DC) in the opposite direction of discharge to restore the active materials in the battery. A battery receives electrical energy from an external circuit and converts it into chemical energy. After discharging, the battery recovers its energy through charging and can be discharged again, completing the charge-discharge cycle. Charging is generally done with DC current. Different charging methods are used in different situations, such as constant current charging, constant voltage charging, float charging, trickle charging, boost charging, or a combination of these methods. There are two main approaches to increasing charging speed: increasing the voltage and increasing the current. Increasing the voltage increases heat generation during charging, accelerates battery aging, and may pose safety risks, making it less effective in practice. In contrast, increasing the current is more practical.

[0003] Traditional new energy vehicle charging equipment is prone to overcharging during charging. Most new energy vehicles cannot effectively prevent overcharging. At the same time, they cannot quickly prevent overcharging during the entire overcharging prevention process. During the entire charging process, the entire overcharging prevention effect is relatively poor, and it cannot respond quickly, which can easily cause the entire battery to burn. There are certain safety hazards when using it as a whole, and it cannot effectively protect the battery.
