Choosing an electric car used to involve one main question: how far will it travel on a charge? As battery technology develops, there is now a little more to consider.
The Volkswagen ID. Polo, Škoda Epiq and CUPRA Raval are all new for 2026 and, although each model has its own design and personality, they share the same advanced foundations. All three are based on the Volkswagen Group's MEB+ electric platform and use a new battery structure designed specifically for compact electric cars: a 37 kWh LFP battery and a larger 52 kWh NMC battery.
While it is tempting to assume that the bigger battery is automatically better, each version has been designed with a different type of driver in mind.
One is an affordable, efficient option suited to urban driving and regular commutes. The other offers greater range and performance for drivers who frequently venture beyond their local area.
So, which MEB+ battery should you choose?
| Feature | 37 kWh LFP Battery | 52 kWh NMC Battery |
|---|---|---|
| Usable battery capacity | 37 kWh | 52 kWh |
| Battery chemistry | Lithium iron phosphate (LFP) | Nickel manganese cobalt (NMC) |
| Official range | Up to approximately 205 miles WLTP | Up to 281 miles WLTP |
| Maximum DC charging rate | Up to 90 kW | Up to 105 kW |
| 10–80% DC charging time | Approximately 23 minutes | Approximately 24 minutes |
| Best suited to | Urban journeys, commuting and regular home charging | Motorway driving, longer journeys and less frequent charging |
*Range and charging figures are based on current Volkswagen information. Actual range and charging performance will vary depending on specification, temperature, driving style, battery condition and charging conditions.
LFP stands for lithium iron phosphate. It is a type of lithium-ion battery that uses iron and phosphate within its chemical makeup rather than nickel and cobalt.
LFP batteries are known for their durability, thermal stability and comparatively affordable production costs. They can also cope well with regular charging, making the technology particularly well suited to smaller, accessible electric cars used for frequent everyday journeys.
The trade-off is energy density. An LFP battery generally needs more space and weight to store the same amount of energy as an NMC equivalent. Volkswagen group has therefore paired the LFP chemistry with the smaller 37 kWh capacity.
That makes it the battery aimed primarily at urban drivers, commuters and buyers who do not want to pay for range they are unlikely to use.
NMC stands for nickel manganese cobalt. This chemistry offers a higher energy density, meaning more energy can be stored without the battery pack becoming excessively large or heavy.
In practical terms, that makes NMC technology useful when a car needs to travel further or deliver more performance from a reasonably compact battery pack.
The 52 kWh NMC battery offers up to 281 miles of WLTP range and is paired with the more powerful 155 kW, or 211 PS, electric motor. It is the more versatile option for drivers who regularly cover motorway miles, travel longer distances or simply want a larger range reserve.
For city driving, the 37 kWh battery could be the more sensible choice.
It offers up to approximately 205 miles of WLTP range, which is considerably more than many drivers cover during a typical week. If your journeys mainly consist of commuting, school runs, shopping trips and travelling around town, the larger battery may spend most of its time carrying unused capacity.
Imagine your daily commute is 15 miles each way. Even after allowing for changes in weather, traffic and driving style, the 37 kWh battery should comfortably cover several working days between charges.
Its smaller capacity also means there is less energy to replace when charging. A home charge can therefore be completed sooner, while a 10–80% rapid charge takes approximately 23 minutes under suitable conditions.
The 37 kWh LFP battery is likely to suit you if:
However, a smaller battery leaves less flexibility when the weather is cold or an unexpected long journey appears in the diary. Drivers without reliable access to charging may also find themselves plugging in more frequently.
If longer journeys are a regular part of your routine, the 52 kWh NMC battery is likely to be the better fit.
Its range of up to 281 miles WLTP gives you approximately 76 additional miles compared with the smaller battery. That extra capacity can make motorway journeys easier to plan and reduce how often you need to stop.
The 52 kWh version can accept DC charging at up to 105 kW, compared with 90 kW for the 37 kWh battery. Despite having considerably more capacity, it can still charge from 10–80% in approximately 24 minutes under suitable conditions—only around a minute longer than the smaller battery.
That makes it better suited to travelling between cities, visiting family further afield or taking the car on holiday. It can also be reassuring in winter, when cold temperatures, heating use and wet roads can reduce an electric car’s available range.
The 52 kWh NMC battery is likely to suit you if:
The main consideration is cost. If the majority of your driving takes place within a small local area, you may be paying for additional range and performance that you rarely use.
Not necessarily.
The 52 kWh battery stores around 41% more usable energy than the 37 kWh unit, but its higher maximum charging rate helps compensate for the additional capacity.
According to Volkswagen, the difference between their quoted 10–80% DC charging times is only around one minute:
These figures describe charging under favourable conditions rather than a speed you will see during every session. The charger being used, battery temperature, starting charge level and the number of vehicles sharing a charging site can all affect the result.
Both versions also support up to 11 kW AC charging, making them suitable for overnight charging at home.
The smaller battery requires less electricity for a complete charge, but that does not automatically mean it will cost less per mile.
Charging costs depend on how much energy the car uses, the electricity tariff and where you plug in. Home charging is usually considerably cheaper than relying on public rapid chargers, regardless of which battery you choose.
As a simple illustration, at an electricity rate of 25p per kWh, adding 30 kWh would cost approximately £7.50, while adding 40 kWh would cost around £10. The larger battery costs more to fill because you are buying more electricity, but it also carries you further.
For many buyers, the more important financial difference will be the purchase price rather than the cost of each mile.
Probably not, but you do need enough range for your own routine.
It is easy to choose an EV around the longest journey you might complete once or twice a year. A better approach is to consider the journeys you make during an ordinary week.
If you drive 20 or 30 miles most days and can charge at home, the 37 kWh battery provides a comfortable reserve. For the occasional longer trip, a short rapid-charging stop may be a reasonable compromise.
If you cover significant motorway mileage every week, regularly make unplanned journeys or have limited access to charging, the extra range of the 52 kWh battery may be worth the higher price.
Choose the 37 kWh LFP battery if your ID. Polo or CUPRA Raval will mainly be used as a city car, commuter or second household vehicle. It offers useful everyday range, quick charging and the prospect of a lower entry price. For drivers with predictable journeys and convenient home charging, it may be all the battery they realistically need.
Choose the 52 kWh NMC battery if you regularly travel longer distances, spend more time on motorways or want to charge less frequently. Its additional range, faster peak charging rate and more powerful motor make it the more flexible all-rounder.
Ultimately, neither battery is universally better. The 37 kWh version prioritises affordability and everyday efficiency, while the 52 kWh version prioritises range, performance and long-distance flexibility.
The best choice is not necessarily the battery that travels the furthest, it is the one that fits naturally into the way you drive.
