摘要： A device for achieving dynamic charging and balance of battery cells is disclosed. The device is configured for monitoring a plurality of battery voltages from a plurality of battery cells in a multi-cell battery pack. In case of a battery voltage difference between two of the battery cells being greater than a pre-determined voltage difference, the device generates a plurality of balance charging currents for charging the battery cells. In which, each of the balance charging currents is calculated based on remaining charge time, measured battery voltage, and rated battery capacity. Thus, in a charge cycle, one balance charging current for charging the battery cell with low battery voltage is designed to be greater than another one balance charging current for charging the battery cell with high battery voltage. Consequently, elimination of the battery voltage difference existing between any two of the battery cells is achieved.

摘要： 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.

摘要： The invention discloses a power saving device capable of automatically sensing standby current, which is used in a power device such as a power outlet or other power supply devices for giving the power device ability of electricity saving. When the power saving device normally works, a threshold current setting unit of a controlling and processing module is configured to automatically calculate a threshold current based on current signals sensed by a current detecting unit under different operation modes of at least one electrical device electrically connected to the power device. Moreover, when at least one standby current sensed from the electrical device is determined to be lower than the threshold current, the controlling and processing module immediately switches a switch unit to an open-circuit state, thereby causing the electrical device unable to receive electricity from the power device. Consequently, the power device exhibits the ability of power saving.
