Frequently Asked Questions
EV Chargers
AC chargers are differentiated by their power ratings. We commonly hear about chargers rated at 2.4kW (often a general-purpose outlet or GPO), 3.5kW, 7.4kW, 11kW, and 22kW. But what do these numbers mean in practical terms?
The Bottom Line
Your choice of AC charger significantly influences how quickly you can charge your EV. For those regularly on the move, investing in a higher capacity AC charger like the 7.4kW or even the 22kW can be a game-changer.
However, always consult with an EV expert or your car manufacturer to ensure compatibility and optimal charging for your specific vehicle.
What do these numbers tell us?
Efficiency Matters
The table assumes a charger efficiency of 99%. The actual mileage you get in one hour can slightlydiffer based on the efficiency of your charger and the energy consumption of your EV.
Speed vs. Power
A 7.4kW charger provides nearly three times the range in an hour compared to a standard GPO anddoubles that of a 3.5kW charger. Therefore, upgrading to a higher power AC charger significantly boosts your chargingspeed.
Overnight Charging:
If you typically charge your EV overnight (for about 10 hours), using a 22kW charger can add awhopping 1089 km, while a GPO would only add about 118.8 km.
Future-Proofing:
As EVs evolve and come with larger battery capacities, having a more potent charger at home meansyou’re better prepared for the future. A 22kW charger, for instance, ensures quicker full charges even as batteries growin capacity.
- If the charger cannot contact the internet, it will blink blue, white.
- Make sure you’re within 10 meters of the charger.
- Turn off the charger and wait 15 seconds, then turn it on. In 2-3 minutes if there is a blue/white indicator, the charger hosted Wi-Fi network will become visible. This will be available for 15 minutes.
- The network name is ‘Serial number – serial number’ (e.g. ‘abcdef-abcdef’), select this to access the charger Wi-Fi configuration page.
- Make sure you’re connected to the Charger’s access point. (If you’re not connected to the access point, see above)
- For most clients, the Configuration Page will automatically appear.
- If it doesn’t, enter the URL: http://evos-wifi.setup/index.html.

EV charger installation is complex. Generally this isn’t a do-it-yourself (DIY) project unless you have electrical expertise. Improper installation poses significant risks, including fire hazards and electric shock. Furthermore, self-installation may invalidate the manufacturer’s warranty on the charging equipment.
Professional Installation
CBI believes that hiring a certified and experienced installer ensure safe and compliant installation. Selecting an installer with specific experience in EV charger installation is highly recommended, as general electrical expertise may not encompass the specialized requirements of EV charging systems.
Safety Considerations
Ensuring the safety of the installation is paramount. A proficient installer will have comprehensive knowledge of the home’s electrical system and the specific EV charger, mitigating risks associated with high electricity transmission.
Compliance and Certification
A qualified installer ensures compliance with national wiring regulations and provides local support, which is hugely beneficial if you run into issues.
Cost Estimation
Installation costs vary based on location and technical specifications. Factors influencing cost include distance between the fuse box and the charger location, cable requirements, and Labor. The cost of electrical components and the need for custom quotes to avoid unforeseen expenses are highlighted.
Utilizing Grants
Exploring national and local incentives for EV charger installation can significantly offset initial costs. These incentives often cover a substantial portion of the installation expenses.
