How Do I Protect My EV Charger from the Rain?


An EV charger, also known as an electric vehicle supply equipment (EVSE), is a device that provides electrical power for charging plug-in electric vehicles (PEVs). They are similar to gas station pumps for gasoline-powered vehicles, but instead of dispensing fuel, they deliver electricity to the battery of an electric car.

How to Protect My EV Charger?

While most EV chargers, including the 7KW 11KW 22KW IP65 model, are already designed to withstand rain, here are some additional tips for extra protection 7KW 11KW 22KW IP65 Waterproof EV Charger :

Follow the manufacturer's instructions: This is the most important step. The user manual might suggest specific practices or limitations for your specific charger model.

Consider the location: If possible, mount the charger in a sheltered location, like under an overhang or carport, to further minimize direct exposure to heavy rain or harsh weather conditions.

Avoid submersion: While most chargers are water-resistant, they are not meant to be submerged in water. Ensure proper drainage around the base of the charger to prevent pooling water.

Inspect regularly: Regularly check the charger for any signs of damage, corrosion, or loose connections, especially after heavy rain or storms.

Use a weatherproof cover (Optional): While not always necessary, if you're concerned about extra protection, you can find optional weatherproof covers specifically designed for EV chargers. These can further shield your charger from rain, dust, and other elements.

Remember, even with these tips, always prioritize following the manufacturer's recommendations for your specific charger model for optimal safety and performance.

What are the Two Types of EV Chargers?

EV chargers are becoming increasingly common as more and more people switch to electric vehicles. They are an essential part of the infrastructure needed to support the widespread adoption of electric cars.

Level 1 chargers: These are the slowest type of charger, typically adding only a few miles per hour of charging. They use a standard 120-volt household outlet and are typically used for overnight charging at home.

Level 2 chargers: These are faster than Level 1 chargers, typically adding 25-50 miles of range per hour of charging. They use a 240-volt outlet, similar to what is used for dryers and ovens. Level 2 chargers are often installed in homes, workplaces, and public charging stations.

Constraints on Home Electric Vehicle Charging Networks

As intra-city transportation, household electric vehicles are limited by factors such as cruising range. Therefore, a three-level charging network should be established to facilitate residents’ travel. The construction of charging network has the following constraints:

(1) Lack of strong guidance from the government. The government lacks in-depth research and comprehensive planning on the introduction of household electric vehicles in cities and its power supply model, which leads companies to follow the trend and blindly build public charging stations under the control of commercial principles;

(2) The profit structure of investment is not balanced. Although household electric vehicles currently have the technology and market conditions for commercialization, the popularization of electric vehicles will still take several years. The number of users of household electric vehicles in communities is gradually increasing, and community charging facilities are suitable for construction in installments. For example, a community with 1,000 parking spaces will initially build more than 10 charging piles. Later, additional investment will be made phase by phase based on the purchase of electric vehicles by the community. The characteristic of this investment structure is that the initial investment has a large "positive externality", but the profit expectations are very uncertain and the risk is particularly high; while the investment in the subsequent stages, with the gradual popularization of electric vehicles, the investment risk gradually decreases. , the profitability level gradually increases, and the "positive externalities" continue to decrease; when electric vehicles become popular, the investment will be profitable.

This structure of investment in community charging facilities has outstanding advantages. It can flexibly add investment according to the popularity of electric vehicles, which is conducive to attracting social capital to enter. But the disadvantages are also huge. Suppose someone first builds 10 charging piles in the community, then he can only have the income from these 10 charging piles, and the profit is far away. If the operating rights of the remaining 990 parking spaces cannot be won, initially The investment is likely to "come to nothing". Since initial investment and subsequent investment are separated, the risk of initial investment cannot be hedged by subsequent investment, causing everyone to wait and see, hoping to wait until electric vehicles are popularized before investing, so that the current initial investment cannot be started;

(3) Constraints on power production and grid transmission capabilities. The current power supply situation in my country is not optimistic. Power supply shortages often occur at the beginning of the year and during the summer. Under normal circumstances, the power grid can provide a certain amount of power for household electric vehicles, but it may be difficult to guarantee supply during high load periods. The distribution capacity of the grid does not take into account the charging needs of electric vehicles when planning. The number of modern household appliances and total power consumption are increasing year by year. During the peak power consumption periods in winter and summer, the distribution capacity of the grid will not be enough for charging. However, community charging facilities are built in phases. The initial small amount of charging demand conflicts with power production and grid distribution, but the problem is not very prominent. Although the long-term gap is large, it can be improved with the pace of electric vehicle promotion. The power grid is optimized and transformed.

EV Charger Five Frequently Asked FAQ

What is an EV Charger?

EV Charger, or electric vehicle charger, is a device that provides electrical energy to electric vehicles. EV Charger can be installed in public places, private residences or commercial places to provide convenient charging services for electric vehicles.

What types of EV Chargers are there?

EV Charger can be divided into slow charging, fast charging and ultra-fast charging according to charging power. The power of slow charging is generally 3-7kW, and the charging time is 6-8 hours; the power of fast charging is generally 10-60kW, and the charging time is 0.5-2 hours; the power of ultra-fast charging is generally more than 120kW, and the charging time is 15-30 minutes.

How to use EV Charger?

The steps to using an EV Charger are as follows:

Insert the charging gun into the charging port of the electric vehicle;

Swipe your card or use the mobile APP to start charging;

After charging is completed, pull out the charging gun.

How is the cost of EV Charger calculated?

The cost of an EV Charger is generally calculated based on the amount of electricity or charging time. In public places, the cost of an EV Charger is usually 1-2 yuan per kilowatt hour; in private residences, the cost of an EV Charger is usually 0.5-1 yuan per kilowatt hour.
