mercedes-benz-350e-charging-guide

The Mercedes Benz C 350e has quickly become one of the most popular electric vehicles in the UK, with the PHEV finding favour with company car drivers in particular. The low running costs combined with the usual attributes of Mercedes’s excellent C Class makes for an attractive proposition for those looking for a plug-in car. Available as either a saloon or an estate, the C 350e has an electric range of 19 miles on a single charge.

The Mercedes Benz C 350e is eligible for the OLEV Category 2 Plug-in Car Grant, which provides buyers with £2,500 off the cost of a new model. Buyers will likely also be eligible for the Electric Vehicle Homecharge Grant, worth £500 off the cost of a fully-installed home charge point.

Next Green Car says: “The Mercedes Benz C 350e proves a very cheap car to run, with all the prestige that comes with the three-pointed star on the front.”

Mercedes Benz C 350e Charging inlets

Like most PHEVs, the Mercedes Benz C 350e is only able to use slow and fast chargers – there is no rapid charge capability. As such there is one inlet which, in the case of the Mercedes Benz C 350e, uses the Type 2 charging standard.

Mercedes Benz C 350e Charging times

Below is a table showing approximately how long it will take to charge a Mercedes Benz C 350e. Times are for a 100% charge, but it is worth noting that these times are only a guide as PHEV drivers will often not use an entire charge to complete their journey.

Other factors that might vary the charging time – either reducing it or extending the time taken – include the issue of battery capacities having upper and lower charge restrictions to extend battery life and protect against potential damage, and charging rates slowing down as maximum charge approaches.

The Mercedes Benz C 350e is fitted with a 3.7 kW on-board charger. This means that even when connected to a fast charger with a higher maximum output, the Mercedes Benz C 350e will only be able to accept up to 3.7 kW.

.

The Mercedes Benz C 350e should only cost around 4p per mile to run in electric mode, though that’s with a number of variables in your favour. Expect 5p-6p per mile for a more accurate real world cost, presuming that the majority of charging is done at home. Prices for a full charge are almost a worst case scenario, with many charges carried out before the battery of the Mercedes Benz C 350e gets down to 0%.

According to a Zap-Map survey, 85% of EV drivers charge their car at home, making it an important aspect of owning an electric vehicle. The most common level of charge for an EV to get down to before being charged at a public point is 21%-30%, with 60% of drivers surveyed starting charging between 11% and 40%. Only 10% of drivers regularly see a charge of 0%-10% before they start charging, though this figure is likely to be a little higher when considering only PHEV drivers because of the back-up provided by a petrol powertrain.

Buying a Mercedes Benz C 350e will likely entitle you to an Electric Vehicle Homecharge Scheme (EVHS) grant. This will give you up to £500 off the cost of a fully installed charge point at home. Certain criteria need to be met, and off-street parking needs to be available too.

Costs vary depending on installer and charge point chosen, though you can find out more information by clicking on the button below.

Mercedes Benz has partnered with Chargemaster to offer guidance to home charging points and installation when buying a new C 350e PHEV. Customers don’t have to buy a charge point from this supplier, but it means the process will be a little more streamlined, and organising an installation can be started at the dealership. There are a number of different points and prices on the market so it is worth shopping about beforehand so you know what’s on offer.

 

How to charge a Mercedes Benz C 350e

mercedes benz c 350e charging

The Mercedes Benz C 350e is available with a single charging standard – a Type 2 socket found on the rear bumper beneath the off-side light cluster.

There is one socket for the Type 2 connector, which is used for charging at home or in public. The cables will have a Type 2 connector at one end to plug in to the C 350e, and either a typical three-pin plug for any UK mains socket, or a Type 2 connector at the other for a home unit or public points.

This Type 2 connector is used for home charge units and public charge points as the standard across the UK and Europe, allowing drivers to access charge points on the move.

Charging requires the user to simply plug the connector into the port, before the car then ‘talks’ to the charging unit to make sure there is a power supply, that there are no faults, and that it is safe to start charging. If charging at home or at some work place charge points, there is no further need to activate the charging process.

In public though, there will usually be an activation process needed. Depending on the charge point provider, this will often be an RFID card or smartphone app, usually linked to an account you have already set up. Once activated, the car and charge point will have the same ‘conversation’ as when plugged in at home, before starting the charging process.
