A control device includes a processor. The processor controls an electric power supply to an operating part, and charging and discharging of a secondary battery; estimates electric power being supplied to the operating part and the secondary battery; acquires a charge state for a case of charging the secondary battery; and when a determination is made that the electric power estimated by the processor and being supplied to the operating part and the secondary battery is less than electric power required for a predetermined action to be executed by the operating part and, also, the charge state of the secondary battery is a predetermined charge state, controls so as to limit the predetermined action.

Embodiments of the present disclosure disclose a method for charging, an apparatus for charging, a device and a storage medium. The method includes determining a degree of change in charging performance of a battery corresponding to a current voltage range when the battery is in a charging state; determining an adjustment amplitude of a current charging current based on the degree of change when the degree of change satisfies a condition; determining a target charging current based on the adjustment amplitude and the current charging current; and charging the battery with the target charging current.

Systems and methods for monitoring the health of a vehicle battery. A method includes determining an initial amp-hour value for a vehicle battery of a vehicle. The method also includes measuring a net integrated amp-hour value added into the vehicle battery during a first time period. The method further includes determining that the initial amp-hour value plus the net integrated amp-hour value is greater than a threshold percentage of a rated capacity of the vehicle battery. And the method still further includes responsively providing an alert to a driver.

To perform charge/discharge control of a storage battery at an appropriate timing. In a battery controller, a battery information acquisition unit acquires information on the storage battery. A degradation progression rate calculation unit calculates a degradation progression rate of the storage battery based on the information acquired by the battery information acquisition unit. A limit value setting unit sets a limit value for controlling charge/discharge of the storage battery based on the degradation progression rate calculated by the degradation progression rate calculation unit. A timing determination unit determines a timing at which the limit value needs to be output based on the information acquired by the battery information acquisition unit. A limit value output unit outputs the limit value to a host controller based on the timing determined by the timing determination unit.

A management apparatus for an energy storage device, wherein after the start of counting an elapsed time since a current of the energy storage device became equal to or smaller than a first threshold, when a predetermined condition in which the voltage of the energy storage device is possibly not stable is satisfied at a time point where the count reaches a stabilization time (predetermined value), the count of the elapsed time is changed.

A charging cable is configured to rotate freely while attached to a cable plug on a chargeable device. The plug has contact pads separated by an insulator, and the matching cable head has pins for contacting the pads of the plug. There may be a ‘deadzone’ position where one or more pins of the cable head rest of the separator and do not make contact with the charge pads on the cable plug. The examples include pins in the cable head for redundant charging paths that are complimentary such that only one of the power paths will be on at any given time.

An electronic apparatus includes a connector to be connected to an external apparatus, a second measurer which measures current flowing through a secondary battery, the secondary battery being supplied with power by being electrically connected to the external apparatus, or voltage at the connector, and a controller which acquires a charging state of the secondary battery and determines whether or not an abnormality has occurred to a connection state between the external apparatus and the electronic apparatus, based on the acquired charging state and a measurement result measured by the second measurer.

A detection circuit for control pilot abnormality of a DC charging pile, which is electrically connected to a control pilot signal generating circuit and a control circuit, providing instant protection for the DC charging pile while control pilot (CP) abnormality been detected. The detection circuit includes a control pilot (CP) signal potential discrimination module, a charging-discharging module electrically connected to the CP signal potential discrimination module, and a controller protection triggering module electrically connected to the charging-discharging module, wherein the CP signal potential discrimination module justifies the voltage level of the input CP signals been input, activates the charging-discharging module to charge the CP signals to a steady-state voltage higher than a predetermined voltage level within a certain time period, and activates the controller protection trigger module to provide instant protection for the DC charging pile.

An estimation system, includes: a secondary battery; a monitoring device that detects a voltage and a current of the secondary battery; and a processor that estimates a full charge capacity of the secondary battery using a detection result of the monitoring device. The processor calculates a first charging rate of the secondary battery using a current integration amount in charging, discharging, or charging and discharging of the secondary battery and using a full charge capacity of the secondary battery that was estimated last time; calculates a second charging rate of the secondary battery using an open circuit voltage of the secondary battery, when a predetermined time has elapsed without charging and discharging since the first charging rate is calculated; and performs correction, when a magnitude of a difference between the first and second charging rates is larger than a threshold, on the full charge capacity based on the difference.

An example method includes receiving, from one or more sensors of a battery module, sensor information indicative of a health status of the battery module; determining, based on sensor information, battery health parameters of the battery module; determining, based on the battery health parameters, a target state-of-charge (SoC) indicating a target battery capacity to which the battery module is to be charged; determining an end-of-charge voltage (EOCV) to be attained at an end of charging the battery module to achieve the target SoC; and commanding a battery charger to charge the battery module until the EOCV is achieved.
