    Abstract: Provided is a power supply device for supplying power to load elements. The power supply device includes a main power module including a main battery, a main power controller configured to control charging and discharging of the main power module, a sub-power module including sub-batteries respectively corresponding to the load elements, and a sub-power controller configured to control charging and discharging of the sub-power module, Based on a remaining capacity of the main battery and a remaining capacity of the sub-batteries, the power supply device is selectively operated in a first mode in which charging and discharging are possible for both the main power module and the sub-power module, a second mode in which charging and discharging are possible only for the sub-power module, or a third mode in which charging and discharging are possible only for the main power module.

    Abstract: The present invention provides an active equalizing charging device and a method using the charging device to charge a secondary battery. The secondary battery consists of a storage battery unit, which includes a plurality of battery modules connected in series. The active equalizing charging device consists of a control unit, a charging unit, a voltage detection unit, and a temperature detection unit. The control unit is coupled to and used to control the charging unit. The voltage detection unit is used to detect the voltage of each of the battery modules. The temperature detection unit is used to detect the temperature of the storage battery unit. The charging unit consists of one first battery charger, one first switch, a plurality of second battery chargers, and a plurality of second switches. The first switch is used to close or open the circuit between the first battery charger and the storage battery unit. Each of the second battery chargers is respectively coupled to one of the battery modules and the power source, and each of the battery modules is respectively coupled to one of the second battery chargers. Each of the second switches are used to close or open the circuit between each of the second battery chargers and the battery modules.

    Abstract: An un-interruptible power supply (UPS) with indication of battery internal resistance includes a processor, a display, an internal resistance sensor assembly and a battery pack. The internal resistance sensor assembly is connected to the processor and the battery pack. The processor is connected to the display, generates a reference internal resistance according to multiple internal resistances detected by the internal resistance sensor assembly within a stable time after installation, generates a stable internal resistance according to an internal resistance of the battery pack detected by the internal resistance sensor assembly after the stable time, compares the stable internal resistance with the reference internal resistance to generate a status of internal resistance of the battery pack, and instructs the display to display the status for user's timely awareness of the condition of the battery pack and prompt action when the performance of the battery pack deteriorates.
