Problems solved by technology
[0002] Due to the needs of the battery management system to debug the voltage acquisition function, it is difficult for the multi-string adjustable power supply on the market to meet the requirements of up to 24S. If the battery is used for debugging, it is difficult to control the change of the single voltage. Up to 24 strings of adjustable power supplies, the cost is relatively large

The invention provides an adjustable power source system used for a battery management system to test and simulate battery single cell voltage. The adjustable power source system is used for simulating electrical core voltage output as high as 24S with single cell voltage output ranging from 0 to 5 V and a maximum output current reaching 800 mA. Voltage output is adjusted via a turn button type adjustable resistor, voltage input is 220 VAC, 24 independent strings of 8 VACs are obtained via conversion conducted through a tapped voltage transformer, a 7 VDC is output via a bridge type rectification circuit, 7 V voltage is input voltage of an adjustable LDO, LDO output is used for controlling output voltage via adjustment of the adjustable resistor, output of a first LDO is a basis ground for a second LDO, the rest can be done in the same manner, and a 24S adjustable simulated power source can be formed. Circuits in the adjustable power source system are simple and can be easily realized, voltage output of a plurality strings of electric cores can be simulated, and output voltage can be adjusted; compared with a conventional multi-string adjustable power source, the adjustable power source is advantaged by great functions and low cost.
Description
technical field [0001] The invention belongs to the field of battery management system testing, in particular to an adjustable power supply system used for battery management system testing to simulate battery cell voltage. Background technique [0002] Due to the needs of the battery management system to debug the voltage acquisition function, it is difficult for the multi-string adjustable power supply on the market to meet the requirements of up to 24S. If the battery is used for debugging, it is difficult to control the change of the single voltage. Up to 24 strings of adjustable power supplies, the cost is relatively large. Contents of the invention [0003] In view of this, the present invention aims to propose an adjustable power supply system for testing and simulating battery cell voltage in a battery management system, and for testing a circuit that simulates the voltage output of up to 24S battery cells. [0004] In order to achieve the above object, technical ...
