In addition, in cases where the electric motor or supply inverter unit continues to supply power to other parts of the high voltage system, such as after an accident or after loss of control of the converter causing the wheels to spin freely, even if the high voltage busbar, high voltage battery has been completely disconnected , the release system of this residual energy will fail and cause other parts of the high voltage system to be electrically unsafe for a long time

The invention discloses a connection device used between a vehicle battery and a high-voltage bus bar, comprising: an electrical connector and a control module. The electrical connector includes a first conductive portion, a second conductive portion, and a first insulating portion between the first conductive portion and the second conductive portion. The control module is configured to trigger the electrical connector to move from the first position to the second position when the vehicle has an accident. Wherein in the first position, the positive pole of the battery and the positive bus bar of the high voltage bus are electrically connected to the first conductive part, and the negative pole of the battery and the negative bus bar of the high voltage bus are electrically connected to the second conductive part. part, so that there is current between the battery and the high-voltage bus. Wherein in the second position, at least one of the negative pole and the positive pole of the battery is connected to the first insulating part, so that there is no current flow between the battery and the high voltage bus.
Description
technical field [0001] The present invention generally relates to the vehicle electrical field, and more particularly relates to a connection device and method for a vehicle. Background technique [0002] In vehicles, the high voltage (HV) system, including batteries, inverters, motors, etc., is critical in terms of safety. Especially in emergency situations, such as in the event of an accident, it is important to quickly and reliably disconnect the high-voltage power source, such as the battery, from other parts of the high-voltage system, such as the inverter or the motor. It is also important to discharge other parts of the high voltage system as quickly as possible to prevent uncontrolled dissipation of charge, for example an arcing event if system components, such as cables, are damaged. [0003] Typically, upon detection of a severe vehicle accident, the battery is disconnected from the vehicle's high voltage bus by opening an electrical contactor. The electrical con...
