An on-vehicle network system includes, for each of a plurality of zones defined in a vehicle, a zone control unit, a power distributor connected to an on-board battery, and a plurality of electronic devices supplied with power from the power distributor via a common power supply line. Each of individual relays is interposed between one of the electronic devices and a body ground of the vehicle to individually turn on and off connection between the one of electronic device and the body ground based on a control signal from the zone control unit.

Disclosed techniques relate to orchestrating power consumption reductions across a number of hosts. A current value for an aggregate power threshold of a plurality of hosts may be identified. During a first time period, an aggregate power consumption of the plurality of hosts may be managed using the current value for the aggregate power threshold. A triggering event indicating a modification to the aggregate power threshold is needed may be detected. A new value for the aggregate power threshold may be determined based on the triggering event. During a second time period, the aggregate power consumption of the plurality of hosts may be managed using the new value for the aggregate power threshold.

Disclosed techniques relate to orchestrating power consumption reductions across a number of hosts. Power consumption of power-drawing devices (e.g., hosts, servers, etc.) may be monitored with respect to a power threshold. When the current power consumption corresponding to those devices breaches the power threshold, or at any suitable time, the system may identify a set of reduction actions configured to reduce aggregate power consumption. The power threshold may be updated dynamically based on the operational status of related systems and environmental factors. A number of response levels may be utilized, each having an association to a corresponding set of reduction actions. The impact to customers, hosts, and/or workloads can be computed at run time based on current conditions and workloads, and a particular response level can be selected based on the computed impact. These techniques enable a sufficient, but least impactful response to be employed.

A system according to the present invention comprises: a power source which generates a first low voltage from a supplied high voltage; a capacitor which suppresses fluctuations in the high voltage; and a first device which operates by using the first low voltage as an electric power source and which increases its own current consumption when supply of the high voltage to the power source has stopped.

A power supply system comprising: a first converter module comprising an AC/DC converter and being arranged to produce an intermediate voltage from an input voltage; a second converter module comprising a DC/DC converter and being controllable to use the intermediate voltage to produce selectively at least two distinct output voltage levels; and a control unit arranged to acquire a flight parameter representative of the flight phase and/or of the altitude, and to control the power supply system in such a manner that the second converter module delivers to each electrical system a power supply voltage that depends on the flight parameter and on said electrical system, and that is equal to one of the output voltage levels.

An energy management system for controlling energy to one or more loads powered by a thermoelectric module, the system is comprised of a load prioritization circuit having a monitoring system interfaced to receive sensor data from at least one sensor. A data processing device receives the sensor data. The data processing device acts upon the sensor data to produce energy management instructions. A control system receives the energy management instructions using them to control energy to all loads.

A switching state of a switching arrangement of an electrical distribution arrangement is optimized. In each switching state, an outgoing circuit of the distribution arrangement is connected to a supply by the switching arrangement via a component. Each state differs from others in that the outgoing circuit is connected to the supply via another component. The switching arrangement has enough switching states that each outgoing circuit is connectable to a supply via two different components. An outgoing circuit is presented based on: operating parameters of the components, a switching state, outgoing loads; environmental parameters of the electrical components, forecasted environmental parameters, and forecasted outgoing loads. Forecasted operating parameters are simulated to compare future operating parameters with limit values. Based on likely exceeding limit values in the future, an alternative switching state is suggested such that limit values are not exceeded.

The present document describes techniques for safe battery charging during high ambient temperatures. These techniques extend device runtime during peak use periods when ambient temperature is high by increasing the possibility for battery charging during high ambient temperature conditions. In an example, a device, during high ambient temperatures, checks future ambient temperatures over a network to identify if the minimum future ambient temperature over a block of time within the next N number of days is predicted to be sufficiently low that, when combined with device-performance throttling, is estimated to reduce the temperature of the battery to below the maximum charge temperature to enable the battery to be safely charged. The device can also use the future ambient temperatures to budget current battery usage by implementing and/or adjusting device-performance throttling.

Disclosed is a monitoring apparatus (10) including a user management unit (11) that acquires, in association with each of plural users, a residual power level of a storage battery used by the user, a detection unit (12) that detects a predetermined event, and a setting unit (13) that sets, when the predetermined event is detected, the degree of urgency of need for a predetermined measure for each user based on the residual power level of the storage battery.
