FAQ

How many levels are there for EV Chargers?

Currently, it is roughly divided into 4 levels, and the charging speed and purpose of each level are different.

1.Level 1 EV Charger

Voltage: 120V

Power: about 1.4kW

Charging time: can provide about 3-5 miles of range per hour

Purpose: suitable for home use, using ordinary household sockets for charging. Due to the slow charging speed, it is usually used for overnight charging or long-term parking.

2.Level 2 EV Charger

Voltage: 240 V

Power: 3.7 ~22 kW

Charging time: can provide about 10-60 miles of range per hour

Purpose: suitable for home, workplace and public places. Compared with level 1 charging, level 2 charging is faster and is currently the most common charging method used in homes and public places.

3.Level 3 EV Charger (DC Fast Charging)

Voltage: 400 ~800V

Power: 50 ~350 kW

Charging time: Can charge the vehicle from 20% to 80% in 20-30 minutes

Purpose: Mainly used in highway service areas, gas stations and other places where fast charging is required. Suitable for fast charging during long-distance travel.

4.Ultra-Fast DC Charging

Higher power range, usually above 150 kW

This type of fast charging station can provide a large amount of range for the vehicle in a very short time, but has high requirements for vehicles and infrastructure.

Different levels of EV Charger are suitable for different scenarios. Choosing the right level according to your needs can improve the efficiency of use.

An Level 1 EV charger will most likely come with the vehicle and can plug into any standard socket.

L2 EV chargers need a plug similar to a household dryer and require an electrician to install.

L3 EV chargers are an entirely different level of installation complexity because of their high-power requirements. You’ll need a licensed electrician to confirm your existing grid is up to the task. Then the work of trenching, laying cable, and connecting to the grid begins. Some engineering firms specialize in L3 EV charger installations, and a quick web search will find them for your area.

Home charging piles are usually designed for long-term use. If they are properly installed and regularly maintained, their service life can reach 10 to 15 years or even longer.

Public charging piles are usually designed to last for 5 to 10 years because they need to withstand higher frequency of use and more complex environmental conditions. Through good maintenance management, their actual service life can be extended.

Ways to extend the life of charging stations

1. Choose high-quality products:14:35:31Buy well-known brands and certified high-quality products.

2. Regular inspection and maintenance:Clean the surface of the equipment regularly to prevent dust and dirt from accumulating.

3. Check whether the connecting cables and plugs are worn or loose, and replace damaged parts in time.

3. Update the software to ensure system safety and functionality.

4. Appropriate protection measures: Consider adding a protective cover when installing outdoors to reduce wind and rain erosion. Try to avoid exposure to harsh environments such as exposure to the sun, high humidity, etc. in extreme weather.

Through the above measures, the service life of electric vehicle charging stations can be effectively extended and their reliability and safety can be improved.

lf you are operating your EV charger as a profit center, there are a few different ways to charge for charging:

1.By time spent.

Charging fees are based on the time spent at a charger, such as in 15-minute increments. This also helps to prevent drivers from remaining in a space after they have finished charging.

2.By power used.

You can charge by the amount of kW used.

3.Per use.

A flat fee is either charged for every charging session or through a membership.

4.Time of day.

There are two reasons you may want to consider this - electricity has different prices that depend on the time of the day, or to extend the amount of use-time by encouraging charging at non-peak times.

5. Member system

Some operators provide membership plans to enjoy preferential prices or free services by paying monthly fees or annual fees.

Month/annual subscription: For example, a monthly or $ 200 per month, you can enjoy a certain amount of free charging or discount price.

Exclusive discount of members: Members can enjoy lower electrical prices than non -member members.

6. Free charging

Free charging services are provided in some places to encourage environmental protection. This usually appears in the following scene:

Shopping centers, supermarkets and other commercial places: In order to attract customers, some commercial places provide free charging services, but there may be time limit.

Government subsidy project: In order to promote new energy vehicles, governments will set up free public charging piles.

In many countries and regions, governments and local agencies offer various subsidies and incentives to encourage the installation of electric vehicle charging stations. Specific subsidy policies vary by region.

You can find out whether there are relevant subsidy policies through the following channels.

Local government official website, power company customer service center or electric vehicle dealers.

For example, the U.S. federal government offers a 30% tax credit to eligible households to cover the cost of purchasing and installing an EV Charger, capped at $1,000. In addition, states also have their own incentives, such as California, which offers up to $500 in cashback for home EV Charger installation.

Electric vehicle charging pile plug standards vary from country to country, mainly divided into two categories: AC Charging and DC Fast Charging. Here are some of the main charging plug standards and their applicable regions:

1. AC Charging

Type 1 (SAE J1772):

Applicable regions: North America, Japan

Features: Single-phase AC, maximum support 80A.

Appearance: Round plug with five pins.

Type 2 (IEC 62196-2):

Applicable regions: Europe, China, etc.

Features: Single-phase or three-phase AC, maximum support 63A (three-phase).

Appearance: Round plug with seven pins, also known as Mennekes plug.

2. DC Fast Charging

HAdeMO

Applicable regions: Japan, some European and North American markets

Features: Dedicated to DC fast charging, supports up to 400A.

Appearance: Large round plug with ten pins.

CCS (Combined Charging System)

Includes CCS Type 1 and CCS Type 2:

CCS Type 1

Applicable regions: North America

Features: Chinese national standard, including GB/T AC and GB/T DC.

GB/T AC is used for AC slow charging, similar to Type 2.

GB/T DC is used for DC fast charging and has a unique design.

3. Tesla Supercharger

Tesla has its own dedicated charging interface, but also provides adapters in some regions to be compatible with other standards.

There is a certain incompatibility between these standards, so when buying electric vehicles in different regions or different brands, you need to pay attention to the type of charging interface supported.

Different countries and regions use different standards, so when traveling across borders, you need to pay attention to whether the vehicle is compatible with the local charging infrastructure. Some car owners may need to purchase adapters to solve incompatibility issues.

The installation cost depends on your location, available power, etc. It may cost tens of thousands of dollars to install an L3 EV charger.

However, if you are a business owner and plan to charge the L3 charger, L3 may be a better installation option. L2 once again depends on the variables listed above, but if the location is correct and the nearby settings may be less than 1,000 US dollars.

This is an average cost of the industry, for reference only, but remember that your installation may be very different.
