Installing EV chargers for business: what do you need to prepare? With real installation examples

Installing EV chargers for a business should start from the number of vehicles and how long they stay parked, then an assessment of the building's electrical system, and finally deciding the charger positions and cable routes to suit the actual site. Every factory, office and business premises has different conditions, so the site should be surveyed before choosing models and finalising the installation scope.

What do you need to prepare before installing an EV Charger for your business?

Prepare 6 items of information to discuss with the survey team: type of business and province, car models and the number of vehicles expected to use the chargers, usual parking times, information on the existing electrical system, photos of the electrical panel and parking area, and the desired charging point locations. If you do not yet know the details of the electrical system, you can send photos for our team to carry out an initial check and arrange a further survey.

1. Start with the users and parking times

Charging points for staff vehicles parked during the day may have different requirements from points serving customers who stop briefly. Specify who will use the charging points, how many vehicles will use them at the same time and when they need to be available. This information helps you choose the number of charging points and type of charger to match actual use, rather than deciding based on maximum power alone.

2. Have our team assess the electrical system and cable routes

Prepare information on the building's electrical system and the location of the electrical panel for our team to consider together with the existing load, cable run distances and the nature of the site. The circuit design, protective devices and cabling must be based on the assessment of that particular site. Equipment sizes from example projects should not be used as specifications for every project.

3. Position charging points for easy use and cable storage

Choose locations that relate to the parking bays and the position of the vehicles' charging ports. Consider pedestrian routes, space for opening cabinets or maintenance access, and cable storage after use. Photos of the area from several angles help our team see the constraints of walls, structures and conduit routes before finalising installation positions.

Real installation example: factory in Pracha Uthit, Samut Prakan

EV Easy installed a 3-phase Model U 22kW with a 10-metre charging cable at a factory in the Pracha Uthit area, Ban Khlong Suan subdistrict, Samut Prakan province, on 17 September 2569 (B.E.). Site photos show the silver unit inside a black cabinet, with electrical equipment and cable storage space. The report for this job states a cable run distance of 14 metres.

This case shows how a charging point is put together in a factory, including the unit, storage cabinet and cable route. The details are specific to this project.

Real installation example: recycling business, Bang Pa-in, Ayutthaya

Another case is the installation of an EV Easy Model Q with a 10-metre charging cable at recycling business premises in Chiang Rak Noi subdistrict, Bang Pa-in district, Phra Nakhon Si Ayutthaya province, on 2 September 2569 (B.E.). Handover photos show the unit in a wall-mounted cabinet beside the building, with electrical equipment and cable conduit. The post-installation report states a cable run distance of 28 metres.

Compared with the Samut Prakan factory job, you can see that the cable run distance and installation layout differ, even though both are charging points at business premises. You should therefore assess the scope and budget based on your own site.

Frequently asked questions

Does every business need to use the same charger model?

No. Choose the model and number of charging points based on the vehicles in use, parking time, the number of vehicles used at the same time and the electrical capacity of the site.

We already have 3-phase power. Can we install straight away?

You should still have our team check the electrical system information, existing load, electrical panel location and cable routes before finalising the installation scope. Having 3-phase power alone is not enough to decide all the details.

How does cable run distance affect planning?

The cable run distance and route are part of defining the scope of work, materials and budget, so you should send photos of the electrical panel and charging point locations for our team to assess, and confirm the details after the survey.

Where are the example projects located?

This article refers to a factory job in the Pracha Uthit area, Samut Prakan province, and a job at recycling business premises in Bang Pa-in district, Phra Nakhon Si Ayutthaya province. You can open the project links to see real installation photos for each job.
