A system is described that turns off a high power, power supply when a device no longer needs high power. A low power, power supply or a rechargeable battery provides power to determine when the device again needs high power. The low power supply consumes a minimum possible power when the device does not need high power and the power rechargeable battery is not charged. That is, the high power and low power, power supplies are turned on or off based on the real time power consumption need of the device and the charged state of the battery. The power need of the device is monitored by a current shunt monitoring circuit and a control signal monitoring circuit.

A sensing apparatuses includes a sensor, a processing circuit that acquires sensor output information from the sensor, a communication circuit that transmits transmission information corresponding to the sensor output information, and a clocking circuit that generates time information. The communication circuit receives time information for correction before the processing circuit starts acquiring the sensor output information. The clocking circuit corrects the time information based on the time information for correction received by the communication circuit. The processing circuit starts acquiring the sensor output information based on the corrected time information.

A method for operation of UPS modules connected in parallel is provided. The method includes: in a case that a UPS system is constructed based on multiple UPS modules connected in parallel, sleeping, based on a system load rate, a predetermined number of UPS modules to control the UPS system to operate at a predetermined efficiency level; controlling UPS modules not being slept in the UPS system to enter into a main-inverter power supply mode or a main-bypass common mode to perform reactive power and harmonic compensation; and waking up the slept UPS modules when the system load rate drops by a predetermined value due to a sudden addition of a load. The UPS modules can be slept or waked up intelligently based on the system load rate in the dynamic online mode, ensuring that the UPS system operates around highest efficiency.

A backup battery system includes a charging-discharging module and a battery module. The charging-discharging module includes a first connector and a first engaging member. The battery module is detachably connected to the charging-discharging module and includes a second connector corresponding to the first connector and a second engaging member corresponding to the first engaging member. When the battery module is connected to the charging-discharging module, the first connector is joined with the second connector and the first engaging member is fixed to the second engaging member.

A system and method for supplying uninterruptible power includes a housing, a power supply input, a power source equipment input, a first powered device output, a second powered device output, an alternative power supply, and a control module. The control module includes a comparator, a switch, a converter and an injector. The injector includes a regulator and power autonegotiation module. The alternative power supply includes a plurality of battery packs in series. There can also be first and second powered devices with uninterrupted power, even when only one of the powered devices breaks. A power is uninterrupted to the first powered device, even if power is stopped to the second powered device, due to a repair or fault of the second powered device.
