    摘要: An electronic circuit breaker comprising: an input connected to an electric DC power supply; an output connected to a load; the input connected to the output via a switch, said switch is controlled via a switch control line between an “ON”-state and an “OFF”-state; a switch driver connected to the switch control line, said switch driver configured to control the switch; and a switch protection, a voltage detection branch configured to output a first electric potential indicative of the electrical potential difference between the input and the output; a comparator circuit configured to compare the first electrical potential with a first threshold voltage, said first threshold voltage is indicative of an over-current level flowing through the switch; and a gate controller connected to the switch disable line and configured to disable the switch by connecting the switch control line to a potential which causes the switch to enter the “OFF”-state.

    摘要: The present disclosure relates to a battery arrangement. The battery arrangement including a plurality of battery cells, a plurality of battery cell controllers forming a plurality of slave nodes, wherein each battery cell controller of the battery cell controllers is connected to at least one terminal associated with at least one battery cell of the battery cells and includes at least a power electronics arrangement for selectively connecting or disconnecting with the at least one terminal. The battery cell arrangement further includes a master node broadcasting a control information message to the slave nodes, wherein the control information message enables each of the slave nodes to generate an electrical signal with one or more characteristics based on the control information message, by controlling its power electronics arrangement.

    摘要: A body-in-white (BIW) of an electric vehicle includes an integrated battery frame having an integrated cover and a lower tray that may be joined together for holding a battery pack for powering the EV. The integrated battery frame extends between and connects to each of two opposite rocker panels of the BIW and provides a floor of the vehicle for mounting cabin components/assemblies such as passenger seats. The integrated battery frame also functions to enclose a battery compartment for protecting batteries from water intrusion and crash events. The integrated battery frame and BIW of the present disclosure provides an efficient EV architecture that eliminates redundant structures and components, improves load paths, and increases space for batteries.
