A server apparatus includes a communicator that communicates with a charging apparatus for a storage battery pack or an information terminal, and a controller. When the communicator acquires information indicating a status of the storage battery pack from the charging apparatus or the information terminal by a recommended deadline that is recommended to manage the status of the storage battery pack, compared to when the communicator does not acquire the information indicating the status of the storage battery pack by the recommended deadline, the controller makes an adjustment including at least one of discounting a usage fee for the storage battery pack, and increasing points which may be used to pay the usage fee by a user of the storage battery pack.

A battery charger and method is disclosed for detecting when a battery has a low state of health while simultaneously charging or maintaining the battery. A battery charger includes a processor; a non-transitory memory device; a power management device to receive an input power and to output a charging current; a pair of electrical conductors to electrically couple with a battery, and a display electrically coupled to the processor. The display being configured to indicate a bad battery indicator when the battery has a low state of health and whether the battery is good to start.

A transmitter assembly is useful in optimizing the delivery of wireless power to a plurality of receivers. Each receiver measures its own battery need for power and transmits that measurement as a request to the transmitter. The transmitter is configured to normalize and compare battery need requests. The transmitter then allocates pulses of wireless power among the requesting receivers according to their battery need.

A system and related method includes receiving an ambient temperature adjacent to a system, an electric current value of electricity that is conducted into or out of a battery coupled with the system, and a voltage of a battery circuit that includes the battery. An internal temperature of the battery is determined based at least in part on the ambient temperature, the current value, and the voltage. One or more conditions for charging or discharging the battery are determined based at least in part on the internal temperature of the battery, the current value, and the voltage. The battery is charged or discharged based on least on the one or more conditions.

A rechargeable battery kiosk can dynamically alter a charging rate of one or more rechargeable batteries housed within the rechargeable battery kiosk to increase a probability that the rechargeable battery kiosk has an ample supply of fully charged, or mostly fully charged, rechargeable batteries based on an anticipated usage data for the rechargeable battery kiosk.
