A retail environment monitoring device includes an ambient environment sensor; a communications module; a rechargeable battery; a voltage sensor circuit; and an ambient energy harvester. The communications module receives data from the sensor. The battery ...

An energy storage system may include one or more first battery racks, one or more second battery racks, one or more DC/DC converters configured to manage the one or more second battery racks respectively, and a battery system controller configured to monit...

A traction battery is charged or discharged according to power limits that are based on generated state of charge values for the traction battery such that, for a 1C discharge rate of the traction battery at a temperature of 0° C., measured terminal volta...

An exemplary charge indicator circuit indicates the state of charge of a battery. The charge indicator circuit includes a connection jack (10), an indicator module (30), a voltage detection module, a charger IC (60), and a path connection module (40). The ...

Current sensing during recharging of a battery in a portable communication terminal is achieved without the use of a dedicated sense resistor. The type of charger attached to the terminal is established from the measured difference in potential between bat...

The battery charging device obtains an open-circuit voltage at the time of 70% capacity based on information stored in a ROM of a battery package prior to the charge, and upon measuring an open-circuit voltage of the battery package by a voltage measuring ...
