To check the temperature of a charging pile, click on 'temp. displaying' at the system menu page (see figure 9.3.2.2). This will display the real-time temperature of the charging pile inlet/outlet and DC+/DC- of all vehicle connectors.
The importance of maintaining charging piles lies in the fact that influences by the changeable environment and ageing inner parts can cause various faults. Regular examination and maintenance are necessary during both product storage and using processes.
Indoor charging piles should have a protection level of at least IP32 or above, while outdoor charging piles need to have a protection level of at least IP54 to ensure the safety of human bodies and charging equipment in harsh environments with wind, rain, and the need for better insulation and lightning protection.
A charging pile is a type of outdoor charging station with waterproof, dustproof, and corrosion proof functions and an environmental protection design, featuring a protection grade of IP 54.
First, charging EVs at low temperatures significantly increases distribution network harmonics, hence limits the number of EVs that can be charged at the same time. Second, more frequent charging of EVs increases demand from the grid.
Cold weather reduces solar battery efficiency by slowing down chemical processes inside, which means batteries store less energy and charge slower. LFP (Lithium Iron Phosphate) batteries perform better in cold conditions than NMC (Nickel Manganese Cobalt) ones, offering more capacity and safety.
