Description

technical field [0001] The invention belongs to the field of detection devices, in particular to new energy vehicles, in particular to a detection device for automatic resistance adjustment of a shunt. Background technique [0002] The shunt is used to measure a large DC current, and it is made according to the principle that a voltage is generated at both ends of the resistor when the DC current passes through the resistor. The shunt is actually a resistor with a small resistance value. When a DC current passes through, a voltage drop is generated. By measuring the voltage across the resistor, the value of the current flowing through the resistor is indirectly detected. It is mostly used as a power metering component in various electric energy meters. [0003] The new energy vehicle battery pack is the source of power and one of the most important systems of the vehicle. Real-time monitoring of the working current of the battery pack is the basis for safe driving of new e...

Problems solved by technology

The traditional resistance adjustment method is manual operation. After each sensor is tested, manual cutting is performed, and then repeated testing and repeated cutting. It should be noted that the resistance adjustment operation of this shunt is irreversible in one direction. That is to say, during the resistance adjustment process, the resistance value of the shunt resistor can only be adjusted in the direction of increasing, and cannot be adjusted in the direction of decreasing resistance value. Once the resistance value increases beyond the requirements of resistance accuracy, the shunt will be becomes waste, beyond remediation

The test process is cumbersome, the test cycle is long, the test accuracy is not high, and the test efficiency is low. It is not suitable for the requirements of mass production for product testing.
