What is EV charger?

An EV charger, also called charging station, electric vehicle charging station, electric recharging point, charging point, charge point, electronic charging station (ECS), and electric vehicle supply equipment (EVSE), is a machine that supplies electric energy to charge plug-in electric vehicles—including cars, neighborhood electric vehicles, trucks, buses and others.


In recent years, electric vehicles have gained more and more popularity among consumers for their energy saving, environmental protection and fashion advantages, and the construction of charging facilities has been gradually improved.

What authorities are required to approve the installation of private charging posts?

--Electricity company, power supply bureau, property, etc.


Charging piles are not just a matter of finding a place to drill a few holes and pull a wire. If you want to build one, you first need to apply to your city's electricity company and then run to the electricity supply bureau before a professional technical engineer will look at the site and provide a professional construction plan. If it is to be installed in a community, you will also need to obtain the consent of the property owner. The layers of scrutiny are actually designed to ensure the safety of the owners' charging and the safety of the national grid.


In addition to private charging piles, the urban public charging network has also been gradually improved. Tesco has built nearly 180,000 charging terminals in 240 cities across China, with over 100,000 operating online, all ranking first in the industry, and has achieved a 2km charging service circle in cities such as Beijing, Shanghai, Tianjin and Qingdao, providing safe, intelligent and convenient charging services for 450,000 users!


Can residential electricity be supplied directly to the charging piles?

--charging piles need separate electricity


"Everyone has heard of charging piles, but they do not know that with the development of electric vehicle technology, the power of individual charging piles is 3-7kW, far more than the average household appliances, so they need to be designed separately for switching and wiring.


The industry-leading electrical technology and intelligent charging technology team at Tricom can provide you with professional technical solutions and support. TCC currently has 1000+ top technical teams in six R&D bases across China, with 1000+ technical patents.


Where are charging posts usually built?

--Better to install charging posts near underground parking spaces


For private car owners, the first requirement for installing charging piles is to have their own private parking space. Experts say that it is better to install charging posts in underground parking spaces. The power supply can be found near the underground parking space, and there are relatively few pedestrians, so it is relatively simple to lead the electricity to the parking space, and the air line will not hinder others.


With the six technical advantages of "pileless charging, plugless charging, group management and control, modular structure, active protection and flexible charging", TCC has gained high trust from the government and customers, and has built charging networks for a number of city-level BOT projects, in public car parks, city complexes and bus stations. ...... provides charging services for car owners. Users can shake or search for charging stations in the vicinity with one click through the Special Call APP.


Do individuals need to pay for the installation of piles?

--No, most of the cost is borne by the company that builds the piles.


If the installation environment is simple and the cable used is not too much (not more than 30 meters), only the car owner has to pay for the material cost, which is about a few hundred dollars; if the environment is more complicated and the cable is more than 30 meters, plus the labour cost is about one or two thousand. For those who don't want to install private piles, they can download the Tesco APP to quickly match their car with a suitable public charging pile in the surrounding area, and complete charging and payment online.

Is it difficult to construct a personal charging pile?

--depends on the construction conditions on site


There are two types of personal charging posts, one is "wall-mounted" and the other is "floor-mounted". For floor-mounted charging piles, you have to build the foundation, bury the cables, electrify the building, coordinate the space for the installation of the distribution cabinet and notify the vehicle owners to move their vehicles to facilitate the construction. The cables required for the charging posts are thicker than a child's arm. For safety reasons, the cables are not laid on the ground, but are erected from the air, and in some sites, master workers even need to re-strip the previously arranged wire slots in order to lay the cables.


Tesco's unique vehicle block charging terminal and wall-mounted charging terminal, which occupy a small area and are easy to operate, and the box-type integrated intelligent group charging technology will also be a future trend.

How long does it take to install a charging post?

--Generally around three days


Generally speaking, if all conditions are in place, such as property and power supply departments agree, and the installation plan is not very complicated, the installation can be completed in three days. After acceptance by the electricity supply department, the charging post will be supplied with electricity.


What do I need to be aware of when installing a garage?

-- Expert control and consultation with "pile owners" who have experience in installation


According to the operations manager of TCC, the following are the main issues to consider when installing charging piles in underground garages in the community.


a. Measurement of the length of the charging area.


b. Measuring the location from the parking space to ensure normal access for other vehicles.


c. Clarification of the location of the distribution box and confirmation of the power cable alignment distance.


d. Clarify whether there is any dampness and water seepage in the underground garage.


e. Clarify whether there is sufficient light.


f. Test the stability of the signal in the underground garage (when the personal pile is idle and not in use, it can be released by the Special Call App to earn extra income)

How is the electricity charged?

-- Private and public charging piles, charges vary


According to the National Development and Reform Commission's Notice on Electric Vehicle Electricity Pricing Policy, charging facilities set up in residential communities will be charged at the residential electricity price for co-metered users, while charging facilities set up in party and government organs, enterprises and public car parks will be charged at the commercial electricity price. Electric vehicle charging facilities are subject to the peak and valley tariff policy.


Are charging piles safe?

-- Purchase facilities from large enterprises, safety is guaranteed


Safety is a priority in the construction of charging facilities, both in terms of technology and construction. When installing charging piles, they are made to be as enclosed as possible to effectively prevent leakage accidents. For example, the "no power plug" technology of the Tesco, the plug is not charged when the gun is inserted, and is only energised when the code is scanned with the app and "start charging" is clicked. The industry's unique CMS active flexible charging system, real-time monitoring and intelligent management of big data cloud platform, automatic power off in case of abnormalities, not only to extend the battery life, but also to protect charging safety.


Do charging piles need maintenance?

-- Just ask the installation company to check it regularly


The operation and maintenance staff of the charging operation company will regularly check and remove hidden faults to protect everyone's low-carbon travel.
