Well, this guide will answer almost everything to help run your EV charging station business. Setting the right charger at the right location, adhering to local regulations, taking professional help, maintenance after installation, all these are key considerations for DC EV charger installation. Let’s find out everything in detail.
Choosing the Right DC EV Charger
Without an efficient charger, no business can run a successful EV charging station. You will need to consider some important factors when choosing a charger. Factors such as speed requirements, smart features, and weather resistance must be carefully considered.
1. EV Charging Needs
Depending on the charging requirements of the site and customer base, you should select a DC charger. Confirm the charger type and number needed based on the probable number of EVs expected to charge.
2. Power Output
DC EV chargers’ power outputs are normally between 50 kW and 350 kW. The higher the power output, the faster the vehicle charges. Low power chargers work best for short-distance travelers and high power chargers are for fleets or long-distance travelers.
3. Smart Charging Features
Smart charging features ensure a more reliable and efficient charging experience for consumers. Select chargers with features like EV charging management system, scheduling, remote control, and load management. These features ensure proper energy management, real-time data tracking, and reduced costs.
4. Weather Resistance
For outdoor installations, it’s vital to select a model with weather-resistance capability. Opt for chargers with a high Ingress Protection (IP) rating that ensures that the charger blocks moisture, dust, and liquids.
Checking Electrical Capacity Before Installing a DC Charger
Checking the electrical capacity of the selected location is essential. Make sure the capacity can support the high power demands of a DC EV charger.
1. Assessing Electrical System
It’s wise to check the existing electrical infrastructure of your chosen site. Evaluate the existing equipment and wiring. Are all these elements working properly? Or, do they need some upgrades? If necessary, a business owner should upgrade the existing structure and equipment.
2. Main Panel Amperage
As a DC charger is fast and professional, it requires high electricity to recharge electric vehicles. The panel must have sufficient amperage to support the power demand of a DC charger. Sometimes, upgrading the main panel can be helpful to run a charging station for better services.
3. Load Calculation
Businesses need to calculate the load used by the site and find the remaining load for the charging station. If the load used by the site is more than 80% of the total electrical load, upgrades will be a must-step. The weak electrical load can cause unexpected issues like overloading.
Where to Install DC EV Chargers?
If an EV charger is installed at the right location, users can get more advantages and businesses can attract more customers. Some crucial factors must be considered when selecting the installation location for a DC EV charger.
- Public Spaces vs. Private Sites vs. Urban Areas
- Distance from the Electrical Panel
- Cable Accessibility
- Expansion Space
Public Spaces vs. Private Sites vs. Urban Areas: When installing at a public space, make sure the commercial EV charging stations are easily accessible and visible; and the set comes with sturdy configuration for serving many users with the highest convenience.
Private charging station focuses on convenience for fleet vehicles and employees. In this case, the location for the charger doesn’t need to have public access.
Installation in urban areas requires utilizing limited space for more EV owners. Businesses should consider the potential for future business expansion.
Distance from the Electrical Panel: Each business targets to reduce various relevant costs. If the distance of your charger location is less from the electrical panel, you can reduce the cost of cabling and lessen voltage drop. Long distances between the panel and charger lead to power losses and increased costs.
Cable Accessibility: Ensure that the charging cables can reach the parked vehicles. In public charging stations, EVs are parked at different positions and angles. Make sure the wires can reach all the electric vehicles for proper connection.
Expansion Space: Who doesn’t have a plan to expand their business? When choosing a site for chargers, consider keeping enough space to add more chargers in the future. Proper planning ahead will save time and money for future upgrades.
DC EV Charger Installation Process
Before installing an EV charger, be sure you have the right charger and the best location to operate the charging station. Once the electrical system and other relevant things are assessed, you can move to the installation process. Consider following the below steps:
- Site Inspection
- Running the Wiring
- Installing the Charger
- Post-installation Testing
1. Site Inspection
Conducting a careful site inspection is the first step when installing a charger. During this inspection, the expert team will:
- Verify the proposed location for the charger. They will assess physical space, electrical capacity, and power grid. If upgrades are required, they will take necessary measures to make the place suitable for the charging station.
- Identify any installation obstacles, such as structural limitations. They can increase power load or add transformers for successful operations.
- Ensure compliance with local regulations. If anything doesn’t meet local codes and rules, they will change things to meet the demands of local authorities.
2. Running the Wiring
After selecting the location, the appropriate wiring is the next crucial step. Necessary wiring from the power panel to the station will help support the DC fast charger. Heavy-duty cables are required to handle the high level of electricity.
Conduit installation can be needed to protect the power cables. Careful consideration when selecting cables can lessen many hassles and make the charger installation successful.
3. Installing the Charger
The installation process will vary depending on the charger type and purpose.
- First, mount the charger to its location. It may be on a pedestal, a wall, or a customized mount. Secure mounting is a must. Some chargers are large and heavy, make sure to bolt them to ensure secure placement. They’ll stay stable during the charging process.
- To make the charger operational, connect the power supply. Each manufacturer provides a wiring diagram. Follow that to connect the charger to the electrical power source. Ensure proper grounding to prevent any electrical surges.
- If the charger comes with network connectivity and handy features like monitoring charging status and billing, configure network integration according to the manufacturer’s guidance.
4. Post-installation Testing
The charging system should function perfectly if your installation is done correctly. Check the system thoroughly; if it doesn’t work, the expert team can recheck the setup and fix the issue.
Post-installation testing can include power tests, charging tests, and network connectivity tests. The power test confirms that the charging system is running with a suitable amount of electrical power.
Recharge an EV’s battery as a test to check if the charger is delivering the desired amount of power and appropriate charging speeds. If there are smart features like energy monitoring and speed control, confirm that they work properly.
Regulations and Safety Standards for EV Chargers
It’s important to ensure compliance with local regulations and safety standards while installing an EV charger. It will make business operations safe and lead to a profitable journey.
