摘要： Various implementations described herein are directed to a system comprising energy storage circuits connected in series. Each energy storage circuit may comprise a first terminal, a second terminal, an energy storage unit, a pre-charge circuit, and/or a bypass diode. The energy storage unit and the pre-charge circuit may be connected in series to form a series connection between the first terminal and the second terminal, while the bypass diode may be connected in parallel to the series connection. The pre-charge circuit may be configured to close a first current path between the first terminal and the second terminal based on receiving a signal. The bypass diode may be configured to, based on the voltage between the first terminal and the second terminal having an opposite polarity to the voltage across the energy storage unit, close a second current path between the first terminal and the second terminal.

摘要： An inductive electronic identification device and a power-supply-compensation circuit of the same are provided. The power-supply-compensation circuit has a power supply unit and a compensation circuit, and connects to a load unit for supplying the load unit to operate. The compensation circuit receives the compensation signal from the load unit, so that the voltage regulator of the compensation circuit controls the voltage rise and fall of one end of the capacitor of the compensation circuit. The capacitive element switches to the charging or discharging mode according to the power consumption of the load unit. In this way, electrical charges are stored when the load unit consumes less power, and compensation current is provided when the load unit consumes more power, so as to maintain the normal operation of the load unit.

摘要： A battery assembly includes an enclosure, and a plurality of battery modules within the enclosure. Each battery module includes an array of battery cells, one or more first sensors configured to measure one or more first parameters of the corresponding battery module, and a first processor configured to receive sense signals from the one or more first sensors of the corresponding battery module. One or more second sensors are within the enclosure, but external to the battery modules, and configured to measure one or more second parameters of the battery assembly. A second processor within the enclosure is to receive data from each of first processors and the one or more second sensors, and transmit controller input data to a controller external to the battery assembly, the controller input data based on the data received from the first processors and the one or more second sensors.

摘要： The present application describes systems and methods for authenticating rechargeable batteries in a rechargeable battery cabinet. The rechargeable battery cabinet may be a part of a large, scalable, distributed network of rechargeable battery cabinets, in which rechargeable battery cabinets may be removed or added based on consumer demand for fresh batteries. The system and methods may track the rechargeable batteries and where they are located in the rechargeable battery cabinets by first assigning a dynamic identification number, such that a rechargeable battery compartment does not need a static identifier. The system and method may allow for real-time reading of the status of rechargeable battery cabinets and rechargeable batteries in the system. Each rechargeable battery may have a static identifier to uniquely identify the rechargeable battery. This system and method allows for efficient scaling and identification of rechargeable battery within the system.

摘要： An electronic device comprises a power receiving unit and a control unit. In a first mode in which the power receiving unit receives power from a first battery and does not receive power from a second battery, the control unit calculates a first operable time based on a plurality of information relating to the first battery acquired from the first battery, and calculates a second operable time based on information other than information of a discharge current of the second battery among a plurality of information relating to the second battery acquired from the second battery and the information of the discharge current of the first battery acquired from the first battery.
