High voltage box and power battery

The utility model discloses a high voltage box and power battery, high voltage box includes: box body and a plurality of relay, a plurality of relays set up in in the box body, a plurality of relays include: main positive relay and main burden relay, main positive relay with main burden relay is in adopt horizontal setting in the box body. The utility model discloses an inventor's discovery will be led after positive relay and the horizontal setting of main burden relay, the direction of height of main positive relay and main burden relay will with the length direction or the width direction syntropy of box body, thereby can be so that highly obviously the reducing of high voltage box, can so that high voltage box arrange in power battery's box, can improve high voltage box and arrange theflexibility in power battery's box, additionally, need not to carry out the split with the part in the high voltage box, thereby can be so that the high voltage box integrated level be high, the doorand window section bar is
