Abstract: Systems and methods are provided for reliable redundant power distribution. Some embodiments include micro Automatic Transfer Switches (micro-ATSs), including various components and techniques for facilitating reliable auto-switching functionality in a small footprint (e.g., less than ten cubic inches, with at least one dimension being less than a standard NEMA rack height). Other embodiments include systems and techniques for integrating a number of micro-ATSs into a parallel auto-switching module for redundant power delivery to a number of devices. Implementations of the parallel auto-switching module are configured to be mounted in, on top of, or on the side of standard equipment racks. Still other embodiments provide power distribution topologies that exploit functionality of the micro-ATSs and/or the parallel micro-ATS modules.

Abstract: The disclosure provides a mobile terminal and a method for controlling a battery thereof, wherein the mobile terminal includes: a main battery configured to supply power to the mobile terminal, a standby battery and a control device. Wherein the control device is configured to switch on the standby battery to supply power to the mobile terminal when the mobile terminal loses the enough power provided to the mobile terminal by the main battery. With the disclosure, a mobile terminal is allowed to be powered by a standby battery when a main battery fails to supply power, which avoids the inconvenience caused by lower battery power and improves the user experience of the mobile terminal.

Abstract: Circuits and methods providing a electronic power supply applicable to any dual supply rail systems, which require a smooth and uninterrupted output supply and a replica power path and autonomous mode of operation from the system power supply are disclosed. In a preferred embodiment of the invention the power supply is applied to a real time clock. An Innovative Replica Power Path concept and circuit implementation ensures the smooth and uninterrupted transfer of power from one input source to the other. The circuit features a Latched Supply Comparator that guarantees the commutation to the Replica Power Path only happens after the voltage is settled. Zero power consumption from the back-up energy source is achieved in the presence of an alternative higher voltage source. The generated RTC supply voltage does not suffer from abrupt changes when the voltage level of the main system power source (battery or charger) is connected or disconnected. The invention allows for maximum utilization of the energy left in the main battery, thus extending the life of the lower capacity backup battery/super-cap.

A first converter a second converter is provided between the fuel cell and the secondary battery and first and second loads. A first inverter is provided between the first and second converters and the first load and a second inverter is provided between the first and second converters and the second load. A first controller controls an output of the fuel cell by controlling the first converter, and a second controller is configured separately from the first controller.

Abstract: A charge controller for a vehicle passive energy system employs an interface to a plurality of charge sources including intermittent sources, such as vehicle mounted solar photovoltaic (PV) panels and the vehicle engine and alternator, and an interface to a plurality of charge loads, such as a comfort heating ventilation, refrigeration and air conditioning (HVAC) system and auxiliary vehicle loads. Charge logic computes which of the plurality of sources will supply the charge current and which of the plurality of loads will receive the charge current, and a switch responsive to the charge logic will direct the charge current from at least one of the plurality of sources to at least one of the loads, the plurality of charge sources mutually exclusive from simultaneously powering a common load.

Abstract: A busway system enables multiple interchangeable power support redundancies to be provided to electrical loads. The busway system includes multiple busways extending through an aisle space, where some busways carry power from separate primary power sources, and one or more busways carry power from a secondary power source. Busways are coupled to loads to provide power support directly to the loads, indirectly via devices that distribute power to the loads via branch circuits, etc. The power support redundancy provided to a load is established based at least in part upon which busways are coupled to the load, and power support redundancies can be changed by changing the couplings of particular busways with the loads. The busways can extend through the aisle space in a staggered configuration to enable load balancing between busways by restricting loads in certain regions of the aisle space to coupling with certain busways and not others.

Abstract: The invention relates to a power management system for supplying backup DC power to peak and/or high current demand battery applications, such as motor starting or an uninterruptible power supply (UPS) used to power a critical load, such as, a data bus or other critical load, after an event, such as loss of primary AC or DC input, during relatively cold ambient temperatures. Two or more heaters can be provided; for example, a low power heater and a high-power heater. In a maintenance mode, the low power heater is used to maintain batteries at a predetermined temperature. In this mode, a battery charger is used to power the low power heater. In a boost mode, after the primary AC or DC input is restored, and battery temperature is too low to back up the critical load, the battery charger supplies power to one or both of the heaters. Since capacity of the battery charger is normally insufficient to heat the batteries to an acceptable operating temperature in a relatively short period of time, a portion of residual power from the batteries is used to boost power to the heaters in order to speed up the time to get each battery of said batteries to its rated operating temperature.

Abstract: Battery charge function may be in an LED driver which eliminates the duplication of line interface circuitry. A single line interface circuit provides the input power conversion for both the battery charge function and normal operation of the LED driver. During a loss of power, the LEDs may be controlled using power from the battery backup module.
