As electric vehicles (EVs) transition from niche to mainstream, one technology continues to power the change quietly but effectively—the ev ac charger. While rapid DC chargers attract attention for their speed, the ev ac charger serves as the everyday hero, supporting residential, workplace, and destination charging scenarios globally.
In this article, we explore the integral role of the ev ac charger in today’s EV ecosystem, highlighting its working principle, key advantages, industry applications, and how it aligns with the future of green mobility.
What is an ev ac charger?
An ev ac charger is a type of electric vehicle charger that supplies alternating current (AC) electricity to an EV. Inside the vehicle, the onboard charger converts this AC power into direct current (DC), which charges the battery. This conversion process is handled internally, making AC chargers simpler and more affordable to deploy compared to high-power DC fast chargers.
Most ev ac charger units are rated between 3.7 kW and 22 kW, suitable for use in homes, offices, parking lots, and commercial spaces where EVs can remain parked for a few hours.
How Does an ev ac charger Work?
This internal unit converts the AC electricity to DC, storing it in the EV’s battery.
Key components include:
- Charging cable (Type 1 or Type 2)
- Wall-mounted or pedestal unit
- Communication interface (for smart functions)
- Safety features like RCDs, overcurrent protection, and surge guards
Charging speeds vary based on the vehicle’s onboard capacity, the charger’s output, and the power supply (single-phase or three-phase).
Benefits of Using an ev ac charger
1. Affordability
The ev ac charger is significantly less expensive to install and maintain than DC fast chargers, making it ideal for homeowners and small businesses.
3. Energy Management
Modern ev ac charger units can be programmed to charge during off-peak hours, optimizing energy usage and reducing electricity costs.
4. Simplicity and Reliability
AC chargers have fewer components, reducing the likelihood of mechanical or software failure.
Use Cases for ev ac charger
1. Residential Charging
Homeowners benefit from the ev ac charger by charging their vehicles overnight. A 7.4 kW charger can typically replenish 30–50 kWh in 6–8 hours, perfect for daily commuting needs.
2. Apartment Complexes
Property managers can install shared charging infrastructure using RFID access or app-based systems for tenant billing and monitoring.
3. Corporate Offices
Employers offering EV charging as a perk can install 11 kW or 22 kW ev ac charger units for employees, helping support green commutes.
Types of ev ac charger
AC chargers can be classified based on their power output and use case:
Level 1 AC Charger
- Power: ~1.4 kW (120V)
- Use: Residential
- Charging speed: 3–5 miles/hour
- Best for overnight or emergency charging
Level 2 AC Charger
- Power: 3.7–22 kW (240V single/three-phase)
- Use: Homes, businesses, public spaces
- Charging speed: 10–75 miles/hour
- Most commonly used charger type worldwide
The ev ac charger can also come with tethered (fixed cable) or socket-only (bring-your-own-cable) configurations based on user preferences.
