Mercedes EQC range, battery and charging

The Mercedes EQC is competitive with its key rivals in terms of range, although a Tesla Model X will go further

The Mercedes EQC’s official WLTP-tested range of 259 miles is better than an Audi e-tron, but falls short of the Jaguar I-Pace and Tesla Model X's figures. Our (fairly brief) real-world test drive suggests it’ll do well over 200 miles to a charge in mixed driving, or closer to 240 miles if you spend most of your time around town. However, it’s disappointing that the EQC’s fastest charge rate is 110kW, where the e-tron will take a 150kW charge. 

Mercedes EQC range

The Mercedes EQC has a claimed WLTP range of 259 miles from its 80kW lithium-ion batteries, which is lagging a little behind rivals like the Model X and Jaguar I-Pace. However, on our test route around Norway, which took in mostly sedate A-roads or urban streets, we saw an indicated real-world range of well over 200 miles, which is very comparable to both the I-Pace and e-tron.

If you do a lot of trundling about town and make good use of brake regeneration (which, unusually, you must choose to turn on using steering-wheel paddles), you could see 240 miles or more of range.

Charge time

The EQC gets Type 2 and CCS sockets, which gives it access to the vast majority of public chargers. If you can find a public rapid charger capable of delivering the EQC’s fastest 110kW charge time (currently a rarity on UK roads) then you can get a 20-80% charge in well under 40 minutes.

Plug into a dedicated 7kW home charger (which most EQC buyers will have) and you can expect a full charge in around 12 hours. However, the EQC comes with just a 7.4kW on-board AC charger, which means that even if you plug in to a 22kW public AC fast charger, you'll only ever get a charge speed of 7.4kW.

You have to use a DC rapid charger to get anything more than that 7.4kW charging speed. DC rapid chargers plug in to the Mercedes’ CCS port (located on the rear wing of the car where a conventional fuel flap would be) using a cable permanently tethered to the charging station.

They're currently almost all 50kW chargers, which will top the EQC up from 20% to 80% capacity in under 90 minutes. DC chargers offering speeds of 100kW or more are gradually being rolled out across the UK from 2019.

The Mercedes has a water-cooled on-board charger and thermal battery management, which pre-heats the batteries in advance of charging (as long as the system knows a charge is imminent). It then keeps the batteries cool while rapid charging takes place, which promises good things for the longevity of the 80kWh battery.

Battery warranty

The Mercedes EQC’s batteries are warrantied for eight years or 160,000 kilometres. Mercedes will replace or refurbish the 80kWh lithium-ion batteries if they fall to below 70% of their as-new performance within that time.
