Examples disclose a system comprising a power supply, coupled to an output power and an auxiliary power. The system is further comprising a controller to interrupt the output power through a switch coupled to the output. The controller is to interrupt the output power based a determination the output power is below an output threshold. The controller is further to interrupt the auxiliary power coupled to the output. The controller is to interrupt the auxiliary power based on a determination the auxiliary power is below an auxiliary threshold. Additionally, the system discloses the switch is to disconnect the output power.

A universal smart energy transformer module (USETM) that uses an array of sensors to monitor and measure characteristics of the electrical power delivered and utilized at a location, along with other conditions in the area surrounding the location. The invention then uses the data from these sensors to determine the condition and performance of the transformer (for example, its input and output, power quality etc.) and also to identify any anomalies detected within the local power system that could threaten reliable electric supply on the electric grid, or pose a danger to people. A notification of such condition may be distributed using the secure, uninterruptible communications system.

A micro controller unit (MCU) includes a flash memory, wherein the flash memory determines a key value of an application when the MCU is powered on, and, when the key value of the application is invalid, the flash memory enters a mode that enables reprogramming of the flash memory.

An apparatus for managing power of a vehicle and a method of controlling the same, for effectively shutting off dark current are disclosed. The method includes determining a first battery state when a preset first condition is satisfied; cutting off a first portion load or all loads based on the determination of the first battery state; determining a second battery state when a preset second condition is satisfied; and releasing load interruption or cutting off a second portion load except for the first portion load from the all loads based on the determination of the second battery state.

An apparatus for managing power of a vehicle and a method of controlling the same, for effectively shutting off dark current are disclosed. The method includes cutting off a first load part when a preset first time condition is satisfied, additionally cutting off a second load part when at least one of a preset second time condition or a first battery state condition is satisfied, and additionally cutting off a third load part to interrupt all loads when at least one of a preset third time condition, a second battery state condition, or a dark current state condition is satisfied.

Described and shown is a process for preparing an emergency energy storage device, with at least one energy storage element for operation, whereby the emergency energy store is designed to provide emergency electrical energy for at least one energy consumer, whereby the energy (E.sub.L) which can be drawn from the emergency energy storage and/or the peak output (P.sub.max) which can be drawn from the emergency energy storage is determined and the operational readiness is established as soon as the energy (E.sub.L) which can be drawn from the emergency energy storage and/or the peak output (P.sub.max) which can be drawn from the emergency energy storage has reached a definable minimum energy value. A process for preparing an emergency energy storage device for operation in which the emergency energy storage is discharged via a discharging device and the heat occurring at the internal resistance (R.sub.i) is used to heat the emergency energy storage device.

A power management system for selectively providing power to one or more electrical loads using a standby generator includes a meter mounted transfer switch, a power management module, and a controller. The meter mounted transfer switch is configured to receive electrical power from a utility source. The power management module is configured to receive electrical power from each of the standby generator and the utility source. The controller is in communication with the standby generator and the power management module, and monitors a load on the standby generator and communicates to the power management module to selectively disconnect at least one of the one or more electrical loads based on the monitored load.

This invention has as its objective provision of a method and apparatus to enable the batteries of Electric Vehicles (EV)s to level the electric demand in buildings to reduce demand charges based on instantaneous demand for electric power. This load leveling is done by connecting the EV to the building electrical system by its conventional Alternating Current (AC) recharging connection, and by an additional Direct Current (DC) path supporting intermittent loads. In this way the EV battery stands between the AC energy source and the intermittent load and reduces the electric power drawn from the grid to a constant minimum level, thereby minimizing demand charges.

In general, one or more loads on a vehicle can be connected to both a first voltage source on the vehicle and a backup vehicle power system on the vehicle. If the voltage provided by the first voltage source to the one or more loads satisfies a voltage threshold, the backup vehicle power system does not provide power to the one or more loads. However, if the voltage provided by the first voltage source to the one or more loads falls below the voltage threshold, the backup vehicle power system provides power to the one or more loads.

A platform module having switchable power for a vehicle including a movable member capable of achieving multiple positions and a position sensor. The movable member includes a plurality of ports configured to provide power. The position sensor is configured to detect a position of the movable member. A first port from the plurality of ports is configured to provide power when the movable member is in a first position; and a second port from the plurality of ports is configured to provide power in response to detecting that the movable member is in a second position. Further, a method is provided for switching power to the platform module.
