Super capacitor control module and control method

Abstract

The invention discloses a super capacitor control module and a control method. The module comprises a MCU controller and six super capacitors. The MCU controller is connected with the positive and negative electrodes of a battery in an automobile circuit through P + and P- lines. The super capacitor module composed of six super capacitors is connected with the positive and negative electrodes of alead battery through a magnetic memory switch and P + and P- lines. The super capacitor module is connected in parallel with the battery. The MCU controller and a charge switching relay are connected. The charging switching relay is connected with an emergency charging input port and P + and P- lines. The MCU controller is connected with the super capacitors through an upgrade step-down circuit.The magnetic memory switch absorbs the reverse high voltage generated by the parasitic inductor of an output wire through a reverse electromotive force cancellation circuit. The super capacitors can enhance the starting performance of the automobile battery, and can assist or start an automobile independently when the automobile battery is in a state of power loss.

Description

technical field [0001] The invention relates to the technical field of automobile supercapacitors, in particular to a supercapacitor control module and control method for enhancing the starting performance of automobile batteries and enabling emergency start of automobiles Background technique [0002] In recent years, supercapacitors have been widely used in automobiles. They have ultra-low internal discharge resistance, a wide temperature range of -40°C to 65°C, and a charge-discharge cycle life of 1 million times. [0003] The parallel application of supercapacitor and battery can improve the starting performance of the locomotive. Supercapacitors are of great significance in improving the starting performance (higher starting torque) of cars in cold weather. At -20°C, because the performance of the battery is greatly reduced, it is likely to fail to start normally or require multiple starts to succeed. However, when the supercapacitor can be connected in parallel with t...

Problems solved by technology

[0007] Both of the above two applications have their advantages and disadvantages: the method of directly connecting to both ends of the car battery in parallel, without circuit control, cannot realize emergency start of the car under the condition of battery power loss, and still needs external access to the battery or Other starting power supply to assist starting; the method of emergency starting can be used for emergency starting in the state of car battery power loss, but it cannot be connected to both ends of the car for a long time to achieve real-time auxiliary starting and enhanced starting in the normal state of the battery

The long lifetime of supercapacitors is also underused

Moreover, the above operations require the user to have certain professional knowledge and hands-on ability. For ordinary consumers, it is a relatively difficult problem to deal with, so it is particularly important to solve this type of problem.
