[0002] At present, the HVIL on the market judges the contact status of the high-voltage plug-in through the on-off of the interlock terminal of the high-voltage plug-in. After passing the logic judgment, the controller issues instructions to control the high-voltage contactor in the high-voltage cabinet. Power on and off the whole vehicle or cut off the high-voltage electrical path of the whole vehicle, but the high-voltage plug-in terminal of the high-voltage battery box itself is in a charged state, which is dangerous. Under special conditions such as accidental touch, loading and unloading collision, there may be a risk of short circuit or electric shock

The invention discloses a high voltage interlocking contactor structure for high voltage battery PACK cabinet bodies. The high voltage interlocking contactor structure for the high voltage battery PACK cabinet bodies comprises the high voltage battery PACK cabinet bodies and high voltage interlocking contactors, wherein the high voltage interlocking contactors are arranged in the PACK cabinet bodies. The high voltage battery PACK cabinet bodies comprise the first PACK cabinet bodies and the second PACK cabinet bodies, and an external circuit is arranged between the first PACK cabinet bodies and the second PACK cabinet bodies. According to the high voltage interlocking contactor structure for the high voltage battery PACK cabinet bodies, each high voltage interlocking contactor with an auxiliary contact is additionally arranged into each individual high voltage battery PACK cabinet in order to control the positive electrode of a high voltage output connected with the cabinet; when the contactors cannot pull-in, a positive terminal cannot connect with the positive electrode of a internal battery, so that a power-off state of the whole cabinet is guaranteed, and safety of the battery device and operators is protected.
Description
technical field [0001] The invention relates to a high-voltage interlock contactor, in particular to a high-voltage interlock contactor structure for a high-voltage battery PACK box. Background technique [0002] At present, the HVIL on the market judges the contact status of the high-voltage plug-in through the on-off of the interlock terminal of the high-voltage plug-in. After passing the logic judgment, the controller issues instructions to control the high-voltage contactor in the high-voltage cabinet. Power on and off the whole vehicle or cut off the high-voltage electrical path of the whole vehicle, but the high-voltage plug-in terminal of the high-voltage battery box itself is in a charged state, which is dangerous. Under special conditions such as accidental touch, loading and unloading collision, there may be a risk of short circuit or electric shock. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention...
