The electric car's motor, controller, battery, and other important parts are generally waterproof, under normal circumstances, it does not matter even if it is wet by rain, but this does not mean that the electric car can walk through the water at will. Because the motor of the electric car is generally located in the heart of the rear wheel, encounter water more than half of the wheel, then the motor will be damp or water, it is very likely to trigger the horn does not sound, brake failure, the controller can not work properly and a series of problems. In addition, many owners like to carry the charger with them, then riding in the rain is easy to cause the charger to moisture into the water.
Recently, the continuous rainfall across the country, many cities, the water on the road is very serious, in this case is not suitable to ride the electric car travel, because the electric car in the water, will cause damage to parts, and may even cause spontaneous combustion, leakage and so on.
The summer heat and high temperatures, charging process battery warming fast, dangerous, but there is another danger in the summer is often heavy rainfall weather, of example, some time ago the typhoon, the eastern coast of some areas of the storm, electric car charging need to pay attention to more matters.
How to use the charging pile correctly?
- after riding in the rain, you can put the electric car in a ventilated place to dry. Before power access, it is best to use a rag or paper towel to wipe the battery and connection socket clean, which can be limited to prevent power short circuit, transmission, motor burn and other dangerous situations.
- in the rainy day it is recommended that owners in the canopy shelter charging, try to avoid direct exposure charging, if it is still raining, it is recommended that the rain stops before charging, if it is Wu carport open-air charging, it is recommended that you can use something like canvas to cover the power supply and interface, remember not to wrap the power supply to prevent charging accidents caused by untimely heat dissipation.
- the current smart charging pile, each outdoor outlet is equipped with a rain cover, the connection between the power supply and the charger to avoid water, in addition to the socket does not plug the charger does not carry electricity, safety protection.
- do not charge electric vehicles in the stairwell, evacuation routes, safety exits, their own living rooms; do not charge for a long time, away from flammable items; use the smart charging pile for electric vehicles charging.
Charging pile waterproof technology
During the construction of charging facilities, ground hardening and foundation protection will be carried out at the bottom of the charging facilities, so that 20-30cm below the charging pile body has the ability to prevent water flooding.
At the same time, the national safety requirements for charging piles are also very strict. Before charging is started, both the car end and the pile end have to be insulated, and if the insulation test fails (when there is serious flooding or conductive objects), charging cannot be started. The charging pile has a minimum requirement of IP56 for waterproofing, and there will be no problem with spraying at any angle after charging is connected. Finally, the charging pile is also designed with short-circuit protection, lightning protection, overload protection and leakage protection, etc. If a short circuit occurs during charging, the device will also cut off the charging current at the first time.
The DC charging pile is added to the AC charging pile on the basis of input overvoltage / undervoltage protection, output overvoltage / undervoltage protection, overtemperature protection, overcurrent protection, current reversal protection and other further safety features.
However, in case of thunderstorms, it is better not to charge outdoors as much as possible. This is because the charging post is metal, the electric car is also metal, and the charging cable is an energized wire, the whole adds up to a small lightning rod system. If a lightning strike, high voltage electricity will instantly break through the battery, causing the battery core to catch fire. This and as a child heard "do not hide under a tree when thunder" is a reason.
