Circuit-implemented analog power supply

Abstract

The invention discloses a circuit-implemented analog power supply, which can perform external charge or discharge and simulate internal resistance of a power supply. The analog power supply mainly comprises seven parts including an output current constant-current control part, a constant voltage control part, a sink current constant-current control part, a far end voltage recovery part, a loop current recovery part, a control part and a load. The analog power supply can truly simulate the electrical characteristics of a battery; the battery or the power supply needed in the tests of a BMS andthe like can be perfectly replaced; and the bottleneck and the defect encountered by an ordinary battery in the tests of the BMS and the like are overcome.

Description

technical field [0001] The invention relates to the technical field of analog power supply, in particular to an analog power supply implemented by a circuit. Background technique [0002] In the fields of BMS, battery charge and discharge system, aerospace and other fields, various batteries and simulated power sources are often used for charge and discharge tests, but the current common batteries have the following disadvantages: [0003] 1. The service life of ordinary batteries is short: for example, the general lithium battery is about 2-4 years, and the cycle charge and discharge times are generally only 300-500 times, while in applications such as BMS, frequent charge and discharge are required, and in the long-term After many times of charge and discharge, its life is difficult to meet the test requirements of BMS. [0004] 2. Ordinary batteries have a low safety factor: In BMS and other tests, there are various short-circuit or reverse connection faults, which may c...

Problems solved by technology

[0007] Aiming at the defects of ordinary batteries such as short life, low safety factor, and insufficient flexibility due to their characteristic properties such as chemical properties and physical properties, which cannot meet the high requirements of BMS and other test scenarios, the improved analog power supply of the present invention is precisely to solve the above problems. The pain point of the industry is to realize the analog power supply through a circuit to seamlessly replace ordinary batteries or ordinary power supplies, which perfectly overcomes the safety, service life, and flexibility of ordinary batteries.
