Electromechanical-hybrid-based servo storage battery automation protection device and method

Abstract

The invention discloses an electromechanical-hybrid-based servo storage battery automation protection device and method. The device is arranged between a storage battery and electric equipment and is respectively electrically connected to the storage battery and the electric equipment. The device comprises a voltage detection circuit, a controller and a mechanical switch device, wherein the voltage detection circuit detects the output voltage of the storage battery; the controller receives the output voltage sent by the voltage detection circuit and compares with a set first threshold, when the output voltage is lower than the first threshold, the controller outputs a control signal for disconnecting the storage battery; the mechanical switch device receives the control signal for disconnecting the storage battery from the controller and disconnects an electric connection between the storage battery and the electric equipment according to the control signal for disconnecting the storage battery. When the output voltage of the storage battery is lower than the set first threshold, the electric connection between the storage battery and the electric equipment can be automatically disconnected, so that the storage battery stops the power supply to the electric equipment, so that the necessary electric energy is stored and the storage battery is protected from damage due to the insufficient voltage.

Description

technical field [0001] The invention relates to the technical field of battery protection, in particular to a servo battery automatic protection device and method based on electromechanical hybrid. Background technique [0002] With the advancement of technology and the increase of people's needs, there are more and more additional functional devices on vehicles to meet the needs of users, such as vehicle positioning terminals, vehicle electronic dogs, reversing sensors, driving recorders, vehicle navigation systems and vehicle audio, etc. The device basically needs to be powered by a battery. Sometimes after the vehicle is turned off, the driver forgets to turn off the above-mentioned power-consuming equipment on the vehicle, so that the battery of the vehicle loses power, and the car cannot be started normally. At present, in order to solve the problem that the vehicle cannot be started due to the power loss of the vehicle battery, the emergency starting power supply is u...

Problems solved by technology

Sometimes after the vehicle is turned off, the driver forgets to turn off the above-mentioned power-consuming equipment on the vehicle, so that the battery of the vehicle loses power, and the car cannot be started normally.

At present, in order to solve the problem that the vehicle cannot be started due to the power loss of the vehicle battery, the emergency starting power supply is usually used to charge the vehicle in an emergency. Although this method can also solve the problem that the vehicle cannot be started due to the power loss of the battery, at present, the batteries of many vehicles use lead. Acid battery, this kind of battery has a memory effect, if this kind of battery experiences two or three times of power loss, its ability to store electric energy will be permanently reduced, and eventually it will not work properly with the car

Although some active battery protection device methods have appeared now, these existing devices usually use electronic switches. Because there is a large instantaneous current when the automobile starter motor is working, the existing conventional electronic switches are difficult to meet the requirements. Therefore The practicability of the existing battery protection device method is poor, and it is difficult to make a practical product
