In view of drivers cannot equip their vehicles with conventional intelligent battery monitoring system by themselves because the wire connections of the intelligent battery monitoring system are complex, the present invention particularly discloses a non-contact intelligent battery sensing system showing the advantages of simple circuit framework and low manufacturing cost. Since the non-contact intelligent battery sensing system only comprises a magnetic field sensor and a sensor controlling module, it is very easy for the drivers to equip their vehicles with this non-contact intelligent battery sensing system by themselves. To apply the non-contact intelligent battery sensing system, the driver just needs to firstly dispose the magnetic field sensor at one position near to a power line of a battery to be sensed, and then install a sensor controlling application program in his smart phones. Apparently, the non-contact intelligent battery sensing system further shows the advantage of easy to be installed.
