FAQ
At CoolCharge, we make EV charging simple and seamless. Our FAQs provide clear answers on products, installation, and warranties, so you get the information you need when you need it. For anything else, our team is always ready to help. Charge with confidence today and into the future.
The charging power you need depends mainly on your EV’s onboard charger, which determines the maximum AC charging rate your car can accept. For example, many entry-level EVs support 7.4 kW, while newer or premium models can accept 11–22 kW. Even if you install a higher-power charger (like our 22 kW IO Charger), your car will only draw the amount it can handle, so there is no risk of overloading the battery. Choosing a higher-power charger can help future-proof your home in case you upgrade to a new EV later, or if multiple drivers use the same charging station.
Most regions today use Type 2 as the standard AC charging connector, especially across Europe, the Middle East, Africa, and parts of Asia. Some older vehicles or models imported from certain regions may use Type 1, which has a different physical shape and pin configuration.
In Singapore, Malaysia, and Thailand, the Type 2 connector is used for AC charging, while CCS2 is used for DC charging.

Yes, AC chargers are designed for residential installation and are the most common home charging option. Before installation, your electrician will evaluate whether your home supports the required power supply.
- Single-phase homes typically support 3.7–7.4 kW chargers. Specifically, a single-phase 15A power point is required for 3.7 kW, and a single-phase 30A isolator is required for 7.4 kW charging rates.
- Three-phase homes can support higher outputs such as 11 kW and 22 kW, delivering significantly faster charging. For 22 kW charging rates, a three-phase 32A isolator is required.
- You may need upgrades such as a higher-capacity circuit breaker, a dedicated charging circuit, or even an upgraded main panel if your home’s existing electrical system is operating near its limit. Planning this in advance ensures safe and reliable long-term charging.
- The minimum charging capacity of our IO Charger ultimately depends on the vehicle you are charging (see FAQ No. 1).
Absolutely.
EV chargers draw significantly more power than standard household appliances and must comply with strict safety and building regulations. A licensed electrician, together with the equipment specialist, will ensure:
- Proper wiring and grounding
- Correct circuit breaker sizing
- Safe ELCB/RCCB protection
- Compliance with local electrical codes
Yes. All our chargers are IP-rated.
If you plan to install your charger outdoors, such as in a driveway or carport, they are designed to withstand sun, rain, dust, and temperature changes. Chargers with an IP55 or IP68 rating are well suited for outdoor use, offering strong protection against water splashes and fine particles. Higher IP ratings indicate greater durability and reliability in harsh conditions, reducing long-term maintenance needs. Our outdoor-ready chargers also feature UV-resistant materials, robust housings, and enhanced cable insulation to ensure safe, reliable performance year-round.
Safety is one of the most important aspects of EV charging. Our high-quality chargers include multiple layers of protection, such as:
- Overcurrent and overvoltage protection to prevent damage from power surges
- Undervoltage protection to avoid damage during supply dips
- Short-circuit protection to guard against unexpected electrical faults
- Temperature sensors that automatically reduce charging speed or shut down the unit if overheating is detected
- Leakage protection (ELCB or RCCB) to ensure safe operation and reduce the risk of electrical shock
- These safety features help preserve the health of your EV battery, protect your home’s electrical system, and provide peace of mind for everyday use.
Charging time depends on your charger’s power output and your EV’s battery capacity. You can estimate the total charging time using this formula:
For example: On a BYD Atto 3

- A 7.4-kW charging rate typically adds 30–45 km of range per hour, making it ideal for overnight home charging.
- An 11-kW charging rate can provide 50–65 km of range per hour, suitable for faster top-ups during the day.
- A 22-kW charging rate, if your vehicle supports it, can deliver 90–120 km of range per hour, offering near “destination charging” speeds.
Our EV chargers come with a 5-year warranty, which makes us the industry leader. We cover manufacturing defects, internal component failures, and environmental damage. Our customer support includes features such as remote diagnostics, online troubleshooting tools, and technician access for more complex issues. We aim to provide strong after-sales support that ensures long-term reliability of your partnership with us.
Singapore & Malaysia may offer financial incentives to encourage EV adoption. These can include:
- Rebates on the purchase of home chargers
- Tax credits for installation costs
- Utility discounts for EV owners
- Time-of-use rate benefits for smart chargers
