The invention provides a current detection device and a vehicle. The current detection device comprises a Hall sensor, a microprocessor and a power supply unit. The Hall sensor is located in a magnetic field area generated by electrifying a to-be-detected structure, and the Hall sensor is not electrically connected with the to-be-detected structure; the microprocessor is electrically connected with the Hall sensor and is used for judging whether the current of the structure to be detected is greater than an overcurrent protection threshold value or not according to the output of the Hall sensor and sending an alarm signal under the condition that the current is greater than the overcurrent protection threshold value; and the power supply unit is electrically connected with the Hall sensorand the microprocessor, and the power supply unit is used for supplying power to the Hall sensor and the microprocessor. By means of the current detection device, the function of detecting the currentof the low-voltage distribution box in a non-contact mode is achieved, and the current detection device is small in size, convenient to install, extremely low in consumed power and capable of meetingthe requirement for measurement of the large current of 100 A or above.

    本申请提供了一种电流检测装置与车辆,该电流检测装置包括霍尔传感器、微处理器以及电源单元。霍尔传感器,位于待测结构通电流产生的磁场区域的内部,且霍尔传感器不与待测结构电连接;微处理器,与霍尔传感器电连接,用于根据霍尔传感器的输出判断待测结构的电流是否大于过流保护阈值,且在大于过流保护阈值的情况下,发出报警信号;电源单元,与霍尔传感器和微处理器分别电连接,电源单元用于对霍尔传感器和微处理器供电。通过该电流检测装置,实现了非接触式检测低压配电盒的电流的功能,并且电流检测装置体积小,安装便利,消耗的功率极低,且能满足100A以上的大电流的测量。
