Nowadays, all lithium batteries used in new energy vehicles use DC power, and the input power supply of all charging piles is AC power. That involves a question, how to convert AC power into DC power? The answer is the charging pile, and the ways in which AC and DC charging piles power are input into the tram are also different. The AC charging pile transmits power to the car’s AC charger through a charging gun, and then the charger converts it into DC power for input to the power battery. Inside; the DC charging pile uses the conversion of the pile to output DC power directly to your tram battery, without being restricted by the conversion motor of the tram. Therefore, the DC charging pile charges faster, which is also the reason why it is relatively large, but the DC charging pile The electricity still needs to be controlled by the tram’s BMS battery management system to protect battery safety, so it will also affect the charging power.

During the construction of electric piles, the bottom of the charging equipment must be ground hardened and basic safety protected so that the 20 to 30 cm below the charging pile itself can prevent water from being engulfed.

In addition to regulations on the bottom of charging piles, the country’s safety protection standards for charging pile sockets are also very strict.

For example, before charging, the charging port of a new energy vehicle and its charging pile need to be inspected for insulation. If the insulation inspection is unsuccessful, charging cannot be started.

The charger is also equipped with short-circuit protection. If a short-circuit fault occurs during the charging process, the equipment will cut off the charging current immediately to ensure safety.

Charging on rainy days is not dangerous. However, do not charge if there is water in the charging station, because too much water may cause leakage problems.

Secondly, if we find any abnormalities or alarms in the vehicle while charging, we should stop charging immediately and inspect the vehicle immediately.

Finally, we also need to check whether the charging gun has been soaked by rain and whether there is accumulation of water and debris in the gun to further ensure safety.

Most charging piles are made of SMC fiberglass material, which can ensure long-term use outdoors and can withstand complex climate conditions.

And now they are all Internet charging piles, and the operation status of each charging pile can be checked in the background. If a problem or malfunction occurs, you can receive information immediately in the background to ensure the safety of battery charging.
