The invention discloses a high voltage safety monitoring method and a safety monitoring system. The high voltage safety monitoring method comprises steps of receiving monitoring information of all high voltage members which is transmitted through a bus, wherein the monitoring information comprises effective voltage of corresponding voltage members, performing comparison on the basis of effective voltage of all the high voltage members and the voltage of the power battery, performing early warning according to the comparison result, and if needed, transmitting early warning information. The implementation scheme of the invention can perform early warning on the basis of comparison result between the effective voltage of various high voltage members and the voltage of the power battery, which can eliminate the safety hazard of the electric automobiles or other devices with the high voltage systems, avoids the high voltage safety fault accident and greatly improves the safety of the electric automobile or other device with the high voltage systems.
Description
technical field [0001] The invention relates to the technical field of electric vehicle safety or other fields with high-voltage systems, in particular to a high-voltage safety monitoring method and a high-voltage safety monitoring system. Background technique [0002] According to the national standard "GBT 19751-2005 Safety Requirements for Hybrid Electric Vehicles", the maximum voltage is higher than or equal to 60V (DC) or 25V (AC) (human body safety voltage) as high voltage. Taking electric vehicles as an example, the voltage of batteries used in electric vehicles Almost all of them are greater than or equal to 300V (volts), which are far higher than the safe voltage that the human body can bear, and belong to high voltage. [0003] Taking electric vehicles as an example, all high-voltage components of electric vehicles are connected to each other through high-voltage connectors or high-voltage wiring harnesses. The schematic diagram of the connection of high-voltage co...
