An in-vehicle entertainment system having functionality of operation interface switchable is disclosed. The system comprises an in-vehicle host electronic device and a hub having a host-to-host transmission function. After at least two mobile electronic devices are coupled to the hub, the in-vehicle host electronic device firstly prioritizes a communication order between the two mobile electronic devices, and then lets a display unit show an operation interface (like CarPlay operation interface) corresponding to the mobile electronic device that is prioritized with a first ranked communication order. Moreover, in case of a peripheral electronic device being coupled to the hub as well as the display unit being showing the operation interface, the in-vehicle host electronic device is allowed to access a peripheral electronic device through the hub.

The present invention discloses a battery internal resistance measuring device and a method thereof, wherein the battery internal resistance measuring device comprises a voltage detecting unit, at least one measurement resistor, at least one switch, and a measurement controller. By means of further explanation, the measurement controller at least comprises a differential value calculating unit for treating a differential value calculation or a slope calculation to each two of adjacent voltage sampling values on a waveform of a discharge voltage signal of the battery, such that the measurement controller can subsequently find out a discharge starting point and a discharge ending point according to data of the differential value calculations or the slope calculations. Eventually, the measurement controller calculates an internal resistance of the battery after picking up an open-circuit voltage and a short-circuit voltage from the discharge starting point and the discharge ending point.

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.
