Full node detection circuit of new energy automobile controller high pressure interlocking

The utility model discloses a full node detection circuit of new energy automobile controller high pressure interlocking, a plurality of high voltage interface mode switchs of this circuit respectively with a plurality of series resistance series connections, a plurality of parallel resistance connect in parallel respectively and constitute a plurality of interface detecting element in a plurality of high voltage interface mode switchs that concatenate and a plurality of series resistance both ends, a plurality of interface detecting element concatenate in proper order and the head end is anodal through pull -up ohmic connection DC power supply, the trailing end connection DC power supply negative pole, little the control unit's detection port connects a plurality of interface detecting element head ends that concatenate in proper order. This circuit can realize that the full node state of high pressure detects, effective recognition failure node, and it is few to occupy little the control unit resource, real
