Specifications

During the high-power fast charging process of electric vehicles, the charging cable will withstand a large current and generate a lot of heat at the same time, causing the cable to heat up due to heat accumulation, shortening the service life of the cable, and even causing damage to the cable. cause physical damage and cause accidents such as leakage.

High-power fast charging of electric vehicles will have a significant impact on the temperature of the charging line. The charging cable will undergo energy conversion and loss during the process of transmitting electric energy, and these energy conversions and losses will generate heat, so the temperature of the charging cable will increase as the charging power increases.

When electric vehicles are charged with high-power fast charging, the charging power usually reaches more than 100 kilowatts, and can even reach more than 350 kilowatts. These high-power charging modes require the use of large-diameter, highly conductive cables to transmit power. These cables experience significant resistive losses as they transmit electrical energy and therefore heat up, causing the cable to heat up.

Therefore, in order to ensure the safety and reliability of high-power fast charging of electric vehicles, it is necessary to reasonably design and select charging cables to ensure that the cables can withstand high-power charging scenarios and monitor and control the temperature.
