Opel Grandland Electric Gets 22kW AC Charging: What Does It Mean for EV Owners?
Opel has introduced a new 22kW onboard AC charger for its all-electric Grandland SUV, making it the first passenger car from the brand to offer this charging option. The upgrade is designed to reduce charging time and give electric vehicle owners more flexibility when charging at home, workplaces, and public charging stations.
The new charger is available across three versions: the standard Grandland Electric, Grandland Electric Long Range, and Grandland Electric AWD.
According to Opel, the upgrade can reduce AC charging time by approximately 50% when connected to a compatible 22kW charging point. This means owners can spend less time waiting for their vehicles to charge, particularly when using public AC charging stations.
But what exactly does 22kW AC charging mean, and how does it benefit everyday EV owners?
What Is 22kW AC Charging?
AC charging stands for alternating current charging. It is commonly used when charging electric vehicles at home, offices, shopping centres, and public parking areas.
An electric vehicle receives AC electricity from the charging point and converts it into DC electricity through its onboard charger before storing it in the battery.
The onboard charger’s capacity determines how much AC power the vehicle can accept.
For example, a vehicle with an 11kW onboard charger cannot use the full output of a 22kW AC charging station. Even when connected to a more powerful charging point, it will generally charge at a maximum of 11kW.
However, the Opel Grandland Electric’s new 22kW onboard charger can accept up to twice that AC power, provided the charging station and electrical supply support it.
In simple terms, higher AC charging power means less time connected to a charging station.
How Much Faster Does the Opel Grandland Electric Charge?
The biggest advantage of the new 22kW onboard charger is its shorter charging time.
Opel says the standard Grandland Electric and Grandland Electric AWD use a 78kWh battery, with 73kWh of usable capacity. Their charging time falls from approximately five hours with an 11kW charger to just over 2.5 hours with a compatible 22kW charger.
The Long Range version also benefits from the upgrade. Its 100kWh battery offers 96.9kWh of usable capacity, reducing charging time from approximately 6.5 hours to 3.25 hours.
Here is a comparison:
| Grandland Variant | Usable Battery Capacity | 11kW AC Charging | 22kW AC Charging |
|---|---|---|---|
| Grandland Electric | 73kWh | Around 5 hours | Just over 2.5 hours |
| Grandland Electric AWD | 73kWh | Around 5 hours | Just over 2.5 hours |
| Grandland Electric Long Range | 96.9kWh | Around 6.5 hours | Around 3.25 hours |
These are manufacturer-provided approximate charging times. Actual results depend on charging conditions, battery temperature, charging equipment, and other factors.
What Does This Mean for EV Owners?
The 22kW AC charging upgrade can make everyday electric vehicle ownership more convenient.
Here are some practical benefits.
1. Less Waiting Time at Public AC Chargers
Many public charging points are installed at shopping centres, offices, hotels, and parking facilities.
Drivers often leave their vehicles connected while shopping, working, or attending meetings. With 22kW AC charging, compatible charging points can deliver more power in the same amount of time.
This makes the Grandland more convenient for people who regularly depend on public AC charging.
2. Better Charging at Workplaces
Workplace charging is another area where the upgrade can make a difference.
Employees who park their vehicles for a few hours can receive more energy during their working day. Instead of relying entirely on overnight charging, they can recharge their vehicles during office hours.
3. More Flexibility for Home Charging
Owners with a compatible 22kW home wallbox and sufficient electrical supply can also benefit from faster AC charging.
However, installing a 22kW charger requires suitable electrical infrastructure. Many homes use 7kW or 11kW wallboxes, so owners may need electrical upgrades to use the full charging capacity.
4. Better Use of Public Charging Infrastructure
A 22kW onboard charger allows the Grandland to take advantage of AC charging stations that support higher power output.
This is particularly useful in locations where high-power DC fast chargers are unavailable or unnecessary.
Does 22kW AC Charging Mean Faster DC Charging?
No. This is an important difference for electric vehicle buyers.
AC charging and DC fast charging use different charging systems.
With AC charging, the vehicle’s onboard charger converts electricity before it reaches the battery. With DC fast charging, the external charging station supplies DC electricity directly to the battery system.
Therefore, upgrading the onboard AC charger from 11kW to 22kW does not automatically increase the vehicle’s DC fast-charging speed.
The new Opel upgrade specifically improves AC charging performance. Its DC charging capability remains a separate specification.
Opel Grandland Electric: Range and Performance
Along with the charging upgrade, the Grandland Electric continues to offer different battery and drivetrain configurations.
The standard electric version delivers a claimed WLTP range of up to 519km. Buyers looking for longer driving distances can choose the Long Range version, which offers up to 691km.
The Grandland Electric AWD is the performance-focused option. It uses two electric motors to produce a combined output of 239kW (325hp) and 509Nm of torque.
The AWD model also offers four driving modes:
- Normal
- Eco
- Sport
- 4WD
Additionally, all-electric Grandland variants feature Frequency Selective Damping suspension technology. The system adjusts its damping response depending on road conditions and driving situations to balance ride comfort and handling.
Is 22kW AC Charging Worth It?
The usefulness of 22kW AC charging depends on how and where an owner charges their vehicle.
For drivers who regularly use public 22kW charging points, the upgrade can save several hours during a full charge. It is also useful for people who charge at workplaces or have access to higher-powered home charging equipment.
However, drivers who mainly use an 11kW home wallbox will not experience a charging-time improvement from the upgrade alone.
In short, the technology offers greater flexibility rather than simply making every charging session faster.
Will This Technology Matter for Nepal’s EV Market?
The Opel Grandland Electric’s charging upgrade also highlights an important consideration for Nepal’s growing EV market.
As more electric vehicles enter the country, charging speed is becoming an important factor alongside battery capacity and driving range.
However, the benefit of a 22kW onboard charger depends on the availability of compatible AC charging infrastructure. Owners need suitable three-phase power, a compatible charging station, and an appropriately rated cable to achieve the maximum charging rate.
Nepal’s EV market would benefit from more higher-powered AC charging facilities at commercial buildings, workplaces, hotels, and public parking areas.
For now, Opel has not confirmed an official Nepal launch or local pricing for the Grandland Electric.
