A method of developing a charging profile for charging a lithium-ion battery. A first phase of charging is at a constant current level, with the constant current level selected on the basis of battery resistance during charging and differential voltage (dV/dQ) analysis. A switch point is selected on the basis of a state of charge (SOC) of the battery when dV/DQ values increase. Next is an increasing voltage charging phase, with the voltage rate selected on the basis of charge acceptance and charge time.

Aspects of this disclosure relate to detecting and recording information associated with electrical overstress (EOS) events, such as electrostatic discharge (ESD) events. For example, in one embodiment, an apparatus includes an electrical overstress protection device, a detection circuit configured to detect an occurrence of the EOS event, and a memory configured to store information indicative of the EOS event.

A power storage control system includes a storage battery and a controller. The storage battery supplies electric power to an electric power system in collaboration with a power generator in response to a command value. The controller outputs, to the power generator, a stop signal causing the power generator to stop power generation when a state of charge of the storage battery is larger than a given value. The controller outputs, to the power generator, an execution signal causing the power generator to execute power generation when the state of charge is not larger than the given value. The controller acquires an actual electric power value generated by the power generator. The controller outputs a control signal causing the storage battery to execute charging and discharging for satisfying the command value on the basis of a difference between the command value and the actual electric power value.

With some of switches connected to some of the plurality of power storage modules being in an on state and other switches connected to other power storage modules being in an off state, determination unit of management device does not permit at least one of other switches in the off state to be turned on in a case where at least one switch is turned on and an upper limit value of a current or power allowed to be supplied to load entirely from the plurality of power storage modules with at least one switch being turned on becomes less than or equal to a value before the turning-on of at least one switch.

Power supply system mounted in electric vehicle includes voltage measurement unit that measures a voltage of each of a plurality of cells to ensure both safety of an electric vehicle and convenience of a user. Current measurement unit therein measures a current flowing through the plurality of cells. Temperature measurement unit therein measures a temperature of the plurality of cells. Controller therein determines a current limit value defining an upper limit of a current for suppressing cell deterioration and ensuring safety based on the voltage, the current, and the temperature of each of the plurality of cells measured by voltage measurement unit, current measurement unit, and temperature measurement unit respectively, and that notifies a higher-level controller in electric vehicle of the determined current limit value.

A portable power bank including a rechargeable battery and/or a remote server may detect loss of capacity in the power bank battery. The power bank and/or remote server determines a nominal capacity of the power bank, and an actual capacity of the power bank, the actual capacity being less than the nominal capacity. The power bank and/or remote server compares the actual capacity to the nominal capacity to determine a health value of the power bank battery. When the power bank battery health value is at or below a threshold value, the power bank and/or remote server transmits an indication of the health value.
