A battery state determining device includes a voltage measuring part, a remaining capacity estimating part, an internal resistance measuring part, a calculating part, and an estimating part. The voltage measuring part measures an open-circuit voltage of a storage battery. Based on the measured open-circuit voltage, the remaining capacity estimating part estimates a remaining capacity of the storage battery. The internal resistance measuring part measures an internal resistance in the storage battery. Based on the measured internal resistance, the calculating part calculates a degradation rate of the internal resistance. Based on the estimated remaining capacity and the calculated degradation rate of the internal resistance, the estimating part performs first estimation on a degradation state of the storage battery.

Die Erfindung betrifft ein Verfahren und eine Ladestation zum Beladen einer zyklisch wiederaufladbaren Traktionsbatterie (5) von zumindest teilweise elektrisch angetriebenen Fahrzeugen (4), insbesondere von Elektro- und/oder Hybridautos. Erfindungsgemäß weist eine Ladestation (10) eine Batteriespeicheranlage (8) und eine Ladeeinrichtung (7) auf. Die Ladeeinrichtung (7) weist eine Energieübertragungseinrichtung (11) auf, mittels der elektrische Energie auf eine zu ladende Traktionsbatterie (5) übertragen wird. Die Batteriespeicheranlage weist eine Vielzahl von zyklisch wiederaufladbaren Batterien (B1 bis Bx) auf, die in mehreren Batteriegruppen (BG11 bis BGn4) zusammengefasst sind, wobei als Batterien (B1 bis Bx) Starterbatterien, insbesondere Kraftfahrzeug-Starterbatterien und/oder Blei-Akkumulator-Starterbatterien, verwendet werden. Die Batteriegruppen (BG11 bis BGn4) speisen unmittelbar zeitlich nacheinander während jeweils kurzer Batteriegruppen-Entladezeitabschnitte (t1 bis t30) eine mit der Ladeeinrichtung (7) energieübertragend verbundene Traktionsbatterie (5) mit einem hohen Batteriegruppen-Entladestrom, wobei unmittelbar aufeinanderfolgende kurze Batteriegruppen-Entladezeitabschnitte (t1 bis t30) den hohen Batteriegruppen-Entladestrom und damit einen hohen Ladestrom (1) für die zu ladende Traktionsbatterie (5) über einen längeren Ladezeitraum (T1) ergeben.
摘要:
The invention relates to a method for managing an authorised operating range of a battery, said authorised operating range being limited between a minimum level (BSOC min ) and a maximum level (BSOC max ) of the state of charge of the battery, said method including a step of estimating a state of health in power (SOHP) of said battery, said state of health in power characterising the capacity of said battery to supply a minimum required power level across the entirety of said operating range, said method being characterised in that it also includes a step of determining said minimum level of state of charge (BSOC min ) of said battery in accordance with said estimated state of health in power (SOHP), said minimum level of state of charge being increased when the state of health in power decreases.

Aspects of the present invention relates to providing devices, a system and method for controlling wireless power transfer across an inductive power coupling. The system, particularly, relates to enabling selection of a wireless power outlet of a multi-outlet power transmission surface closest to the location of a power receiver connected to an electric load and placed upon the surface. Accordingly, the multi-outlet power transmission surface comprising two sub-systems, a power transmission system and a signal transfer system, each operable independently and continuously. Further, the signal transfer system controls the activation of wireless power, configured to analyze the signal-quality of each detected communication signal received from a power receiver and thereby to identify the wireless power outlet closest to the location of the power receiver.
