The invention discloses a connection device and method for a vehicle battery and a high-voltage busbar and a vehicle including the device. The device includes: an electrical connector and a control module. The electrical connector includes a first conductive portion, a second conductive portion, a first insulating portion and a second insulating portion. The first conductive portion and the second conductive portion are alternately connected to the first insulating portion and the second insulating portion. The control module is used for triggering 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 battery is connected to the high-voltage bus. Wherein in the second position, there is no conduction between the battery and the high-voltage bus bar; and the positive bus bar and the negative bus bar are electrically connected to the first conductive part or the second conductive part to form a short circuit.
Description
technical field [0001] The present invention generally relates to the field of vehicle electrics, and more particularly relates to a connection device and method for a vehicle and a vehicle including the device. Background technique [0002] In vehicles, high voltage (HV) systems, including batteries, inverters, motors, etc., have stringent safety requirements. Especially in emergency situations, such as in the event of an accident, it is crucial to quickly and reliably disconnect the high-voltage 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 the rest of the high voltage system as quickly as possible to prevent the charge from dissipating uncontrollably. For example, to prevent arcing events when system components, such as cables, are damaged. [0003] A common safety measure is to disconnect the battery from the vehicle's high-voltage bus by opening an electrical contactor whe...
