摘要: A battery balancing system for parallel connected batteries for balancing batteries that are at dissimilar voltages. The system has first and second buses, connected by a current limiter. A high bus takes energy from the highest voltage battery or batteries in the system and transfers the energy through the current limiter to the low bus, which in turn delivers energy to the lowest voltage battery or batteries in the system.

摘要: A power device having high electricity storage performance capacitor is disclosed, which may include a least one high electricity storage performance capacitor, a balancing circuit and at least one Lithium battery. The balancing circuit may be electrically connected between the high electricity storage performance capacitor and the Lithium battery; the high electricity storage performance capacitor may include a capacitor substrate and a plurality of nanometer particles; the nanometer particles may irregularly stack over the surface of the capacitor substrate and there are gaps forming between the nanometer particles to obtain higher specific surface area; in this way, the high electricity storage performance capacitor can attract more negative and positive ions of the electrolytic solution to increase the electricity energy stored in the capacitor. Therefore, the balancing circuit can transmit the electricity energy in the high electricity storage performance capacitor to the Lithium battery to quickly charge the Lithium battery.

摘要: The invention relates to a method for operating a battery system (1) comprising a plurality of battery cells (8) and a battery management system for monitoring and controlling the battery cells (8), wherein the battery management system has a main controller (2) and a first measurement chain (34) and a second measurement chain (36) with in each case a plurality of measurement chips (40, 42) which are designed to redundantly detect measurement data from the battery cells (8) and in each case to carry out diagnoses and state of charge compensation of the battery cells (8). In this case, it is provided that the battery system (1) has a control channel by means of which a hierarchy state of the two measurement chains (34, 36) is defined, wherein, in the event of the breakdown of one of the measurement chains (34, 36), the battery system (1) is changed over to a mode with reduced availability and the hierarchy state is adjusted to the effect that the other measurement chain carries out the detection of the measurement data, the diagnoses and the state of charge compensation. A computer program and a battery management system which are designed to carry out the method and also a battery system (1) and a motor vehicle, the drive system of which is connected to a battery (16), are also specified.

摘要: Some demonstrative embodiments include apparatuses, systems and/or methods of wireless power transfer. For example, a Wireless Power Receiver (WPR) may include a rectifier to convert a wireless charging signal received from Wireless Power Transmitter (WPT into a Direct Current (DC) power signal; a voltage regulator to regulate a voltage of the DC power signal according to a voltage range; a bypass path to bypass the voltage regulator; and a bypass controller to select between directing the DC power signal to the voltage regulator or to the bypass path, based on a voltage level of the DC power signal and the voltage range.

摘要: A system and method for monitoring the status of a system of battery strings is described. The battery string current is measured by a current sensor urged into contact with a metallic element in which the battery string current is flowing. The time history of the battery string current and voltage is interpreted to determine whether the battery string is discharging, charging or in a fully charged state. A moving average current in the charging state is used to establish a threshold for determining whether a thermal runaway condition exists. The moving average is maintained at the value that existed at a time when the battery string has been disconnected from the system current bus.

摘要: Systems and methods for balancing charge of battery cells of a battery pack are disclosed. In one example, battery cell balancing may be improved by balancing battery cells of a battery cell stack simultaneously. The system and method may be particularly useful battery packs that may be constructed with battery cell stacks that vary in a number of series battery cells.

摘要: A converter is to convert at least one of a first voltage output from a first energy storage device and a second voltage output from a second energy storage device. A detector is to detect the first voltage and a current flowing between the first energy storage device and the second energy storage device. Circuitry is configured to control the converter to perform a first constant current control in which a first constant current flows from one of the first energy storage device and the second energy storage device to another of the first energy storage device and the second energy storage device. The circuitry is configured to determine a state of the first energy storage device based on the first voltage and the first constant current while the first constant current control is performed.
