چکیده

The kinetic battery model is a popular model of the dynamic behavior of a conventional battery, useful to predict or optimize the time until battery depletion. The model however lacks certain obvious aspects of batteries in-the-wild, especially with respect to (i) the effects of random influences and (ii) the behavior when charging up to capacity bounds. This paper considers the kinetic battery model with bounded capacity in the context of piecewise constant yet random charging and discharging. The resulting model enables the timedependent evaluation of the risk of battery depletion. This is exemplified in a power dependability study of a nano satellite mission.

Staying Alive Longer: Autonomous Robot Recharging Put to the Test

Autonomous mobile robots are being developed for numerous applications where long-term capabilities would be beneficial. However, most mobile robots have onboard power supplies in the form of batteries that last for a finite amount of time, in which case the robot becomes reliant on human intervention for extended usage. To achieve true long-term autonomy, the robot must be selfsustaining in it...

Staying Alive: A Docking Station for Autonomous Robot Recharging

Autonomous mobile robots are constrained in their long-term functionality due to a limited on-board power supply. Typically, rechargeable batteries are utilized that may only provide a few hours of peak usage before recharging is necessary. Recharging requires a robot to be taken offline, and attached to a battery charger via human intervention. This is unacceptable in environments where long-t...

W Expressing User Profiles for Data Recharging

are rapidly heading toward a world in which the computing infrastructure will contain billions of devices that are carried or worn by their users as they go through their daily routines. These devices require two key resources to function: power and data. The mobile nature of such devices combined with the economic limitations of size and cost makes it impractical to keep them continually conne...

Autonomous Battery Recharging for Indoor Mobile Robots

This paper describes a method for automatically recharging the batteries on a mobile robot. The robot used in this project is the Nomadic .TechnologiesTM Nomad XR4000 mobile robot. The battery recharging system was implemented using the robot's built-in sensors to control docking with a simple recharging station. The recharging station has an AC power plug, an infra-red beacon and a target desi...

Cruising with a Battery-Powered Vehicle and Not Getting Stranded

The main hindrance to a widespread market penetration of battery-powered electric vehicles (BEVs) has been their limited energy reservoir resulting in cruising ranges of few hundred kilometers unless one allows for recharging or switching of depleted batteries during a trip. Unfortunately, recharging typically takes several hours and battery switch stations providing fully recharged batteries a...
