What to do if EV charging cables get too hot


Electric vehicle charging cable is a basic part of electric vehicle charging facilities, and its performance has an important impact on the entire charging process. However, as a new type of wire and cable, its use requirements are different from traditional wire and cable, and there is no clear product standard to regulate it. The standardization of charging cables has become a problem to be solved in the development of electric vehicles.
Most electric vehicle charging cables currently on the market are orange, so will orange become a unified standard? It turns out that the color requirement for the body charging cable in the wire and cable standard is orange, but there is no clear requirement for the color of the charging pile cable, but everyone habitually uses the orange design. In fact, there are still black, dark blue and other charging pile cables on the market, but the number is relatively small. It is estimated that cables of various colors may appear after a large number of charging piles appear in the future.

At present, the supporting chargers of most electric vehicle OEMs do not have PFC function, and the input current is relatively large, and the normal current is about 12A. The lifespan of chargers without PFC is not long, about 2 years. Even if it is not bad, the performance will be affected. The price of this type of charger is about 150 yuan cheaper than that with PFC or is relatively high (depending on the type of components. Domestic or import). If it has PFC, the input is like 7--8A. When the OEM lowers the price, the quality is not guaranteed much. If the wire is hot, the wire needs to be thickened, and try to add a spacer before charging.
