In the transition towards more sustainable mobility, electric vehicle charging plays a key role. While DC fast charging is ideal for specific situations, AC charging remains the most efficient and affordable option for everyday use. In this article, we explore the benefits of AC charging, how it compares to DC charging and when to opt for each. Plus, we show you how chargers ORBIS AC VIARIS offer the best solution for homes and businesses.
AC vs. DC charging: which option to choose depending on the situation?
When talking about charging electric vehicles, it is essential to differentiate between alternating current (AC) and direct current (DC). Each has its own characteristics, advantages and is more suitable for certain usage scenarios.
AC (Alternating Current) charging: the best choice for everyday use.
It is the most common type of charging in homes, businesses and private car parks.
- Main features:
- Electricity is supplied in AC and the vehicle's internal charger (OBC) converts it to DC for storage in the battery.
- It requires more time than DC charging, but is more economical and compatible with the existing electrical infrastructure at domestic and corporate sites.
- It allows you to take advantage of reduced electricity tariffs, such as night-time tariffs, to optimise costs.
- Recommended situations:
- Overnight charging at home or daytime charging at work.
- For urban journeys or daily commuting.
- Optimisation of consumption with reduced electricity tariffs or solar energy.
DC (Direct Current) charging: ideal for travel and emergencies.
It is found at fast-charging roadside service stations or convenience charging facilities such as shopping malls or other short-stay locations.
- Main features:
- The electricity is already supplied in DC, so it goes directly to the battery of the electric vehicle without the need for conversion.
- It is ideal for long journeys, as it can charge from 10% to 80% battery in less than 30 minutes.
- They are more expensive to install and maintain and require more electrical infrastructure.
- Recommended situations:
- Fast recharging on the road during long journeys.
- Use in transport fleets with a need for continuous operation.
- Situations where recharge time is critical.
Comparison: AC vs. DC charging
| Feature | AC load | DC load |
| Speed | Slower (4-8 h for full charge) | Fast (10-80% in 30 min) |
| Installation cost | Under | High |
| Freight cost | More economical | More expensive |
| Typical location | Homes, offices, private car parks | Service stations, shopping centres |
| Suitable for | Daily use, overnight charging, urban journeys | Long journeys, emergency charging and convenience |
AC charging: efficiency and convenience for everyday life
While DC fast charging is essential for certain situations, in everyday use of an electric vehicle, AC charging is the most logical and efficient option.
Affordable and accessible:
The installation of an AC charger is much cheaper than a DC charger, both in homes and businesses. In addition, most electrical infrastructures are already prepared for AC charging, which avoids costly modifications.
Sufficient for everyday use:
An AC charger can charge a 500 km battery in less than 4 hours and provide 100 km in just 35 minutes. For daily commutes of 30 km to work or everyday activities, 2-3 charges per week will suffice, optimising electricity consumption.
Smart and efficient charging:
AC chargers can take advantage of cheaper night-time tariffs and solar power, reducing operating costs and improving energy efficiency.
When to choose AC charging and when to choose DC charging?
- If you are looking for a cost-effective and efficient solution for everyday use, the AC load is the best option. It is ideal for homes, offices and private car parks, taking advantage of reduced tariffs and renewable energy.
- If you make long journeys or need quick recharges on the road, the DC load is the best alternative. Its speed allows you to continue your journey in a few minutes, but at a higher cost.
