With the vigorous development of automotive electrification, there are increasingly more scenarios where various electrical components in the car need to measure and control current, such as BMS current monitoring, current monitoring on motor controllers, PDU current monitoring, OBC/DCDC current monitoring, leakage current detection of charging piles, etc. Vehicle current sensors face high current, high accuracy, and fast speed usage scenarios, and have strict testing requirements.

Test background:

Type of current sensor:

A current sensor is a device that converts a current signal into another analyzable signal. In terms of types, current sensors are mainly divided into precision resistors, current transformers, Hall current sensors, open-loop current sensors, closed-loop current sensors, flux gate current sensors, and reluctance current sensors.

Key points of current sensor testing:

Linearity, accuracy, dynamic response;

A certain Hall sensor user uses a test current sensor and simulates high-speed and high current scenarios in the operation of new energy vehicles using the IT-M3900D series DC power supply. A dual channel DC power supply is connected to positive and negative voltages+GND to provide three-level wiring power for the sensor.
