A display device is mounted on a hybrid vehicle provided with an internal-combustion engine, an electric motor, an electricity storage device configured to store electricity used to drive the electric motor, and a charger configured to externally charge the electricity storage device using electricity from an external power supply. The display device includes a display and a display controller. The display displays a residual capacity of the electricity storage device. When the residual capacity of the electricity storage device is substantially zero, the display controller displays the residual capacity greater than zero on the display.

A vehicle door system is disclosed. The system comprises an actuator, a power source, and a controller. The actuator is configured to adjust a position of a door. The controller is configured to control the actuator with energy provided by the power source. The controller is further configured to identify a charge level of the power source and compare the charge level to at least one threshold. In response the charge level being less than the at least one threshold, the controller is configured to output a warning signal.

Methods are provided for generating an estimated number of workflow cycles able to be executed with a remaining battery capacity of a battery in a device. A workflow cycle comprising a predefined series of tasks of a work application executed during a defined timeframe is defined. Beginning battery capacity is determined at start of work application execution. End battery capacity at completion of work application execution is determined. Battery usage estimate associated with work application is calculated from difference between beginning battery capacity and end battery capacity. The estimated number of workflow cycles able to be executed is based on the remaining battery capacity and the battery usage estimate.

A method implemented by computer for managing the recharging of a battery of an electric vehicle, comprises the steps of carrying out a recharging cycle of the battery of the electric vehicle; measuring the total energy stored by the battery; calculating the variance associated with the total energy; and determining a coefficient associated with the variance. In one development, the step of determining the coefficient associated with the variance is recursive. Various developments are described, which comprise the use of predefined and/or configurable thresholds, the emission of alarms, the use of white noise distributed according to a heavy-tailed law (e.g. Student) and the use of a Kalman filter. System and software aspects are described.

A battery charge state indicator presents an information handling system battery charge state with an illumination element at a housing side surface in response to end user proximity detected at both first and second capacitive sensor electrodes disposed at the side surface. The capacitive sensor electrodes are supported at a nonconductive material, such as a plastic palm rest covered by carbon fiber material, to provide a proximity detection path, and are grounded to an outer surface of the information handling system housing to reduce false detection induced by end user grasp of the information handling system housing.

The techniques described herein relate to computerized methods and systems of at least one of for generating a single light indication pattern via LEDs for a dose detection system, such as for example, based on a use case type and a battery life status type. The use case types may include pairing, manual synching, and/or dose injection, and the battery life status types may include 1 to 3 different states. Another method and system are for reducing drainage of a battery for a dose detection system by monitoring the continuous activation of the power-on module, and/or alerting the user in a manner for the user to take action. At least some of the information obtained from these techniques may be communicated to a paired remote electronic device, such as a user's smartphone.

A display device includes: a display unit configured to display an index corresponding to a deterioration state of a secondary battery and an EV travelable distance; and a control unit configured to control display of the display unit such that a first decreasing amount by which the EV travelable distance displayed on the display unit decreases with the elapse of time until a predetermined condition has been satisfied is less than a second decreasing amount by which the EV travelable distance displayed on the display unit decreases with the elapse of time after the predetermined condition has been satisfied.

Disclosed is a system and method for passenger safety. A sensing unit, remote device, and/or fob may interoperate to provide various alerts and other indications representative of aspects of a context environment proximate to a sensing unit. In this manner, passenger safety may be enhanced.

A method, battery module, an energy storage device and a power management system is provided. The capacity of the module and energy storage device is determined during current balancing between cells of the module. The capacity is subsequently used to control power to and from the energy storage device to maintain the energy storage device within a predetermined range of the maximum capacity of the energy storage device. The determined capacity is used as a maximum capacity for the energy storage device.

Disclosed are techniques to conserve battery of an endpoint device. Example techniques include adjusting the size of messages transmitted by an endpoint device and/or adjusting the transmission rate of an endpoint device. In some configurations, the one or more criteria are used by an endpoint device to determine what data fields to include within a message and/or adjust a transmission rate associated with the transmission of messages by the endpoint device. For instance, the one or more criteria may include the battery level of the device, the time of year, whether the data has already been transmitted by the endpoint device, whether the data has been acknowledged as received by another device, whether the endpoint device has been instructed by another device to reduce the message size and/or adjust the transmission rate, and the like.
