Product Overview: When electric vehicles are charged at high power and fast, the charging cables will bear a large current and generate a lot of heat, which will cause the cables to heat up due to heat accumulation, shorten the service life of the cables, and even cause physical damage and leakage accidents. Through the case description of the article, let's delve into the problem of the temperature rise caused by high-power charging of automobiles.
High-power fast charging of electric vehicles will have a significant impact on the temperature of the charging cable. The charging cable will undergo energy conversion and loss in the process of transmitting electric energy. These energy conversions and losses will generate heat, so the temperature of the charging cable will increase with the increase of charging power.
When electric vehicles are charged using 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, high-conductivity cables to transmit electrical energy. These cables will generate large resistance losses when transmitting electrical energy, so they will heat up, causing the cable temperature to rise.
If the cable temperature rises too quickly or exceeds a certain range, it will have an adverse effect on the cable, such as cable insulation damage, cable deformation, cable aging, etc. These problems will reduce the safety performance of the cable and may even cause serious accidents such as fire.
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 it is necessary to monitor and control the temperature of the charging cables to ensure that the cable temperature does not exceed the safe range. At the same time, it is also necessary to strengthen the maintenance and maintenance of charging equipment, and replace aging and damaged charging cables in time to ensure the normal operation of charging equipment.
