Description

Technical Field

[0001] This utility model relates to the field of automotive supercapacitor technology, and in particular to the application structure of automotive supercapacitors. Background Technology

[0002] Automotive supercapacitors are advanced energy storage devices that fall between traditional capacitors and batteries. They primarily store and release electrical energy through the charge separation layer at the electrode-electrolyte interface (electric double layer effect) or the redox reaction on the electrode surface (pseudocapacitance effect). Currently, in practical capacitor charging applications, circuits using resistors, diodes, transistors, and field-effect transistors balance overcharging and voltage imbalance during charging. Their application aims to prevent overcharging and achieve balanced charging, extending capacitor lifespan and enabling the capacitor bank to meet design specifications for energy storage.

[0003] Existing patent (publication number: CN209516718U) discloses "a supercapacitor balancing circuit and an on-board electronic device. The circuit includes a voltage divider circuit, an amplifier, a first supercapacitor, and a second supercapacitor. The input terminal of the voltage divider circuit is connected to a power supply. The inverting input terminal of the amplifier is short-circuited to the output terminal of the amplifier. One end of the first supercapacitor is connected to the power supply, and the other end is connected to one end of the second supercapacitor, with the other end of the second supercapacitor grounded. The output terminal of the amplifier is connected to a first potential point between the first and second supercapacitors to make the voltage values ​​across the first and second supercapacitors equal. One end of the first supercapacitor is also used to connect to a load to supply power to the load. The technical solution of this utility model solves the problem of voltage imbalance between series capacitors through the virtual short theory of the two input terminals of the amplifier, reducing power supply failures and improving the lifespan of capacitor components."

[0004] In the process of developing this application, the inventors discovered that the charging circuit also has some inherent problems in actual use. For example, the charging circuit has capacitors with relatively large self-discharge (3V, 3000F). After charging is stopped, the voltage of the capacitor will drop to (2V-1.5V) within (1 hour to 10 hours), and drop to (0V-1V) after three to seven days. In order to maintain the capacitor bank at normal working performance, the charging circuit needs to be frequently started. In addition, the high temperature generated by the circuit during charging also poses a significant safety hazard. This is because the high temperature generated by the discharge resistor in the circuit during charging not only affects the heat dissipation of the capacitor bank, but also accelerates the discharge of the capacitor bank, thus posing a safety hazard.

[0005] Therefore, those skilled in the art have provided automotive supercapacitor application structures to address the problems mentioned in the background section. Utility Model Content

[0016] Furthermore, the fuel-saving booster has its external positive and negative terminals connected to the positive and negative terminals of the battery, with the positive terminals connected to each other and the negative terminals connected to each other.

[0017] This utility model has the following beneficial effects:

[0018] 1. The automotive supercapacitor application structure proposed in this utility model, compared with existing automotive supercapacitors, features a Zener diode D1-D1. 10 When in use, it can prevent uneven charging voltage from causing overcharging of a certain capacitor.
