The invention discloses a high voltage detection circuit, a detector, a battery device and a carrying tool. The high voltage detection circuit includes a controller provided with a signal receiving port and a signal output port; a current detection sub circuit used for collecting current signals on the inner side of a main negative switch in a battery high voltage circuit and transmitting the current signals to the signal receiving port; a switch drive sub circuit used for collecting switch control signals through the signal output port and generating corresponding switch drive signals according to the switch control signals. By adopting the technical scheme, an isolation unit and lead cost caused by long distance connection are saved, circuit safety is improved, and switch control signaltransmission distance is shorted. Energy loss of the switch control signals during the transmission is reduced, so that control over the control switch becomes more accurate and switch control signaltransmission speed is also increased.
