As a result, the battery is frequently discharged in the winter, There arises a problem that the vehicle can not be started.

To solve this problem, it is necessary to increase the battery capacity. However, since the increase in the battery capacity leads to a rise in cost or a decrease in fuel efficiency due to an increase in the weight of the vehicle, there is a limit to increase the capacity of the battery. Accordingly, it has been sought to solve the discharge problem of the battery by efficiently operating the electricity consumed in the electric devices and electronic devices mounted on the vehicle without increasing the capacity of the battery.

One of them is a method of measuring battery current using a non-contact type hall sensor. An example thereof is Korean Patent No. 10-1398219 (Registered on Apr. 25, 2015), Korean Registered Patent No. 10-1413483 (Registered on Apr. 25, 2014), Korean Registered Patent No. 10-1413484 , June 24, 2004). The battery current measuring method using the Hall sensor according to the related art, including the above-described prior arts, measures the current of the battery using a hall sensor and measures the operation of the electric device and the electronic device mounted on the vehicle according to the measured current of the battery. Thereby preventing the battery from being discharged.

However, since the battery current sensor using the Hall sensor according to the related art has a structure in which most of the magnetic core (shield member) and the Hall sensor integrated circuit are mounted on the printed circuit board and simply installed inside the sensor body, And the Hall sensor integrated circuit are not firmly fixed to each other. Therefore, in the process of installing the magnetic core and the Hall sensor integrated circuit in the sensor body, the magnetic core or Hall sensor integrated circuit flows or is installed inside the sensor box The distance between the magnetic core and the Hall sensor integrated circuit fluctuates due to the vibration, which has a limitation in accurately measuring the battery current.
