Embodiment Construction

[0023] The device will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] According to its functions and functions, the system circuit is mainly composed of five parts: power supply module, IT8511 DC electronic load, acquisition control module, charging and discharging module, and PC. The power supply module is used as a charging power supply for the battery to be tested and provides driving power for the charging and discharging module. The electronic load is used to change the charging and discharging mode of the battery. The acquisition control module mainly includes a USB A / D conversion voltage acquisition board, a diode, and a transistor. The battery terminal voltage is collected through the USB voltage acquisition board, and the I / O control output terminal of the acquisition board outputs a control signal To control the charging and discharging module, and use the USB data cable to communicate with the PC to realize automat...

Description

1. Technical field: [0001] The invention relates to an economical, simple, stable and accurate device for battery cycle charge and discharge testing, which can perform constant current, constant voltage, constant resistance, constant Power and other modes of automatic cycle charge and discharge tests. Through the expansion of the system hardware, it is convenient to realize multi-channel (up to 4-channel) measurement, and carry out cycle charge and discharge tests on multiple batteries at the same time. 2. Background technology: [0002] Secondary batteries (rechargeable batteries) have been widely used since their invention, and their types are also diverse. According to their chemical types, they can be mainly divided into lead-acid (Lead-Acid), nickel-cadmium (NiCd), nickel-metal hydride (NiMH) and lithium ions (Li + ) These categories of batteries. Compared with primary batteries, secondary batteries have incomparable advantages, so they are increasingly used in energ...
