Range
When it was launched in 2021, the Vauxhall Mokka Electric was badged the Mokka-e and had a claimed WLTP range of 209 miles from a 47kWh (50kWh total capacity) lithium-ion NMC battery. It was updated in 2024 with a bigger, 51kWh usable (54kWh) battery for a claimed WLTP range of up to 252 miles. If you're considering a used version of the smaller battery Mokka Electric, expect a real-world range of around 140- to 170 miles in real world driving. The newer, 51kWh model will manage more like 170- to 230 miles, as it received improved efficiency and a standard heat-pump, as well as the bigger battery.
Vauxhall is a brand that's owned by a huge umbrella parent company called Stellantis, which also manufactures Fiat, Peugeot, Citroen, DS and Jeep models, among others. Notoriously, the Vauxhall Mokka Electric and its siblings including the Peugeot E-2008, will suggest a very optimistic potential range on the dashboard when the battery is full. I lived with a pre-facelift Vauxhall Mokka Electric for a few months and it routinely told me it'd do over 200 miles when I set off with a full battery, and I never saw more than 170 miles in practice - or 140ish miles was more realistic in colder weather at motorway speeds.
Basically, don't believe the range that your Vauxhall Mokka Electric is showing on the driver's readout when it's fully charged; it'll likely fall quite quickly as the battery charge drops, especially if you're on faster roads.
Battery
The Vauxhall Mokka Electric gets a 51kWh lithium-ion NMC battery pack (total capacity is 54kWh). It’s shared with a number of Stellantis brands such as Peugeot, Jeep and Citroen, but manufacturers such as Kia, Volkswagen and Renault all offer larger sizes in their rival crossovers. If you want longer range than the Mokka Electric offers, check out the Kia EV3, MGS5 or MG4, Skoda Elroq and VW ID.3.
The Vauxhall Mokka Electric gets an eight year, 100,000 mile warranty on the battery, and promises to refurbish or replace the battery if it drops below 70% of its as-new performance in that time.
You should be fine in terms of battery degradation, though, as modern electric cars like the Mokka Electric will typically see the battery degrade by around 1- to 2% per year. So, if you're getting a 200 mile real-world range when new, you should expect to lose as much as 20% of that after ten years, for an average real-world range of 160 miles. If you don't need to rapid charge often, and can live with only charging the battery to 80% in routine use, and just charging to 100% when you do occasional longer journeys, then you could well lose less than 10% of the battery's capacity over that first decade.
Charging
The Vauxhall Mokka Electric will charge at up to 100kW from a public DC charger, which is a similar charge rate to what most rivals offer. It means that the Mokka can manage a 10-80% charge in just half an hour if you're plugged into a fast enough rapid charger. An overnight charge from a home wallbox will take around nine hours. You can also set delayed charging which is great if you want to plug in at a certain time but want the car to charge at a different time to take advantage of cheaper off-peak rates.
