摘要： The disclosure describes a method for determining a coulombic efficiency of battery modules of a rechargeable battery using a circuit arrangement connected to the battery modules and that has a plurality of switching modules for selectively connecting every single one of the battery modules in a common current path or for alternatively isolating every single one of the battery modules from the common current path and from at least one power semiconductor element, which can be operated in linear mode, for regulating the current that flows through the current path. The switching modules are used to select at least one of the battery modules and to connect it in the current path while all other battery modules are isolated from the current path by the switching modules. The selected battery module is subjected to at least one discharge process and at least one charging process via the current path.

摘要： An electricity distribution device is connected to a system power supply and a battery pack, and includes: a primary power converter circuit converting DC electric power discharged from the battery pack into electric power supplied to the load; a first switch switching conducting and non-conducting states between the primary power converter circuit and the load; and a control circuitry controlling the first switch to switch the conducting and non-conducting states between the primary power converter circuit and the load. The primary power convertor circuit consumes DC electric power discharged from the battery pack, in a state where the first switch switches the non-conducting state between the primary power convertor circuit and the load, and a current value is acquired when discharging from the fully-charged state to an empty state. The fully-charged capacity of the battery pack is measured using the acquired current value.

摘要： Systems and methods for charging a plurality of battery strings are provided. The individual string current of each of the individual battery strings can be monitored and used to regulate a charging output provided by the charger. For instance, the output voltage of charger can be controlled as part of a closed loop control system based on the individual string current of the battery string under the constraint of an individual string current limit and/or a charging voltage limit. As the charging voltage of the charger increases as a result of the closed loop control based on the individual string current, other battery strings can be coupled to the charger when the charging voltage provided by the charger exceeds a battery string voltage associated with the battery string.

摘要： A condition estimation device includes a voltage measurement circuit, memory, and a controller. The voltage measurement circuit measures an open circuit voltage (OCV) of an electric storage device. The memory is configured to store first information on a correlation between a positive electrode potential and an electric storage capacity and second information on a correlation between a negative electrode potential and an electric storage capacity. The controller is configured to: measure an OCV under charge or discharge; calculate an electric storage capacity of the electric storage device having the OCV equal to a reference voltage; correct at least one of the first information and the second information such that a potential difference at the calculated capacity is equal to the reference voltage; and generate an OCV characteristic based on the first and the second information after the at least one of the first and the second information is corrected.

摘要： A method of rapidly testing the discharge capacity of a battery comprises discharging the battery at a first discharge rate until a first cutoff potential is reached, relaxing the battery during a first period, discharging the battery at a lower discharge rate until a second cutoff potential is reached and relaxing the battery during a second, longer period. The process is repeated with successively lower discharge rates and successively longer relaxation periods until the battery is substantially exhausted. The cumulative value of all of the discharges is taken as a tested capacity of the battery. Optionally, cleanup charges can be sent to the battery during the relaxation periods and a low-frequency, low-amplitude current can be supplied throughout testing in order to shorten testing time.

摘要： The method for determining the state of charge of a battery can be used during charging or discharging of the battery at constant current. It comprises placing the battery in open circuit during a recovery period until the voltage at the terminals of said battery stabilizes at a voltage plateau. Then a constant test voltage is applied to the battery terminals during a preset test period. The state of charge of the battery corresponds to the current measured at the end of the test period by means of a previously obtained calibration curve.
