Example Embodiment

[0021] In conjunction with the accompanying drawings, the specific embodiments of the present invention are further described:

[0022] In one embodiment, a supercapacitor battery capacity detection system includes: an electronic computer, a tested supercapacitor battery, a detection device, a relay, a temperature sensor, and a single-chip automatic control system. The electronic computer communicates with the single-chip microcomputer through the serial port. The electronic computer stores the test software for controlling the charging and discharging of the battery. The testing device transmits the test data of the DC electronic load and the DC power supply from the serial port to the computer through the software. The single-chip microcomputer controls the opening and closing of the relay to test the super capacitor battery. The testing device includes a DC power supply for charging the battery, a DC electronic load for testing the battery capacity, and testing software. Th...

Abstract

The invention relates to the detection field of a super capacitor battery, and discloses a detection system of the battery capacity of the super capacitor. The detection system of the battery capacity of the super capacitor comprises the super capacitor battery to be tested, a data storage unit, a detection device, a relay, a sensor and an automatic control unit, wherein the automatic control unit is connected with the super capacitor battery to be tested respectively through the sensor and the relay. The invention further discloses a detection method of the battery capacity of the super capacitor. The detection system and the detection method of the battery capacity of the super capacitor have the advantages that the entire process is totally automatic, human intervention is reduced, and test efficiency is improved.

Description

technical field [0001] The patent of the present invention relates to the detection field of supercapacitor battery capacity, which discloses a detection system and detection method of supercapacitor battery capacity. Background technique [0002] As batteries are used more and more widely, the state's support and investment in the battery industry has continued to increase, the entire industry has developed rapidly, and new products have emerged one after another. Some existing standards have been difficult to meet the production needs of enterprises and need to be improved urgently. For example, the existing domestic standards and industry standards do not have information on power density (the product of the discharge cut-off voltage corresponding to the state of charge of the battery and the maximum discharge current is the discharge power, and the ratio of the discharge power to the battery mass is the power density) and The energy density (the actual capacity multiplie...
