Description

A split AC charging pile

technical field

The invention relates to the technical field of new energy vehicles, in particular to a split type AC charging pile.

Background technique

AC electric vehicle charging pile, commonly known as "slow charge", is a power supply device that is fixedly installed outside the electric vehicle and connected to the AC power grid to provide the AC power supply for the electric vehicle on-board charger (that is, the charger that is fixedly installed on the electric vehicle).

The working principle of the existing AC charging pile is shown in Figure 6. A DC voltage is loaded at both ends of the battery, and the battery is charged with a constant high current. The voltage of the battery gradually rises slowly until it reaches a certain level, and the battery voltage reaches the nominal value. When the SoC reaches 95% (for different batteries, it is different), continue to charge the battery with constant voltage and small current, and you can choose various modes such as constant power, constant time, constant amount, and automatic (until full), generally ordinary pure electric cars It takes 4-5 hours to fully charge the electricity with the AC charging pile, and the AC charging pile is cheap. It is mainly installed in the parking lot. The AC charging pile installed in the parking lot has a relatively large workload. The user drags the charging cable during use. Install the charging plug on the charging vehicle. During the dragging process, the cable will rub against the ground. In addition, the large amount of use will cause the external wear of the cable, and gradually expose the internal cable, resulting in the occurrence of the internal cable and the ground. Physical friction, wear of the inner cable sheath, and then cause the cable to leak electricity, which affects the use of the charging cable here, and during the use of the cable, due to the different positions and directions of each user's parking, the cable is caused. In use, the torsion force is relatively large, and the charging core inside the cable is bent due to the torsion force, and in severe cases, it will break. The cable is damaged, which further affects the use of the cable. At the same time, most of the charging piles are fixed during installation. In summer, the cable is affected by sunlight and high temperature, and the sheath has a certain degree of wear, resulting in Oxidation occurs in the external cables, and local cracks appear, which aggravate the cracking of the cables, reduce the service life of the cables, and cause the charging piles to be unable to be used normally, resulting in the inability to charge new energy vehicles.
