Why MG’s 11 kW on-board charger makes life easier

11-08-2021
The time it takes to charge an electric car battery depends on several factors. One of these is the car’s on-board charger. The new MG Marvel R Electric and MG5 Electric are both equipped with an 11 kW on-board charger as standard for extra fast charging. Find out how to take advantage from this on-board charger to make life with an EV even more pleasant.

Let’s start with the things that affect the charging speed of an EV battery. Because with this knowledge, you can choose the right charge points. The time it takes to charge the battery depends on these factors:

1) The maximum power the charge point can deliver (in kW).
2) Whether the charge point works with alternating current (AC) or direct current (DC).
3) The car’s on-board charger that determines the maximum power (in kW) that can be used to charge the battery with AC.
4) The battery capacity in kWh.

Keep in mind that the weakest link determines how quickly the battery is charged eventually in kW/min. How long it eventually takes to charge the battery to a certain percentage, depends on the battery capacity obviously. Factors like ambient temperature and battery condition also affect the actual charging time.

For now, let’s leave DC fast charging aside for a while and look at the on-board charger of the MG Marvel R Electric and MG5 Electric for charging with AC. So number 3 of the above factors that determine the charging speed. AC applies to almost all charging points at home, at work, on the street in the residential area, in parking lots, and so on.

New generation electric vehicles

The MG Marvel R Electric and MG5 Electric are two new generation electric vehicles with the latest technology in terms of battery capacity and charging capacity. They are both equipped with an 11 kW on-board charger for AC as standard. This means the battery can be charged with a maximum of 11 kW, excluding the charging capacity of the charge point.

For example, if you can charge at home or at work with a 7 kW AC charge point, the battery of the MG Marvel R Electric and MG5 Electric can never be charged with a higher capacity. The maximum power the charge point delivers, is the weakest link in this case. By way of comparison, the MG ZS EV, MG’s first all-electric model in Europe, has a 6.6 kW on-board charger. In this case, the 6.6 kW on-board charger is the weakest link.

Public AC charging

But here’s the thing: more than 60% of all public AC chargers in Europe have a 11-22 kW grid connection. With the new Marvel R Electric and MG5 Electric, you get the most out of these charging points. The charging speed is almost two times faster than possible with the MG ZS EV. Nothing to the disadvantage of the MG ZS EV, by the way, because the battery in the MG Marvel R Electric is also considerably larger. The capacity is 70 kWh compared to 44.5 kWh with the MG ZS EV. Charging from 0 to 100% takes roughly between 6 and 7 hours for both models.

How many kilometres you can drive with a full battery varies per model. It’s all about pumping as many energy as possible into your battery within a certain time frame to gain as much driving range as possible. And thus make everyday life with an EV even more pleasant.

Geared to your requirements

MG models are increasingly geared to the requirements and wishes of European motorists, but also to the European infrastructure. With the new MG Marvel R Electric and MG Electric, you get the most out of the public AC charge points available in Europe. Especially when you are charging your EV battery for 1 to 2 hours for example, while you are shopping in the city centre or doing your weekly shopping, you can take maximum advantage of MG’s 11 kW on-board charger. Keep this in mind when searching for an available charge point nearby.
