    PHEV and hybrid car servicing: Our complete guide

    As governments, companies and individuals become increasingly aware of the climate crisis, alternatively-fueled vehicles are becoming more prominent on our roads – notably, hybrid and plug-in hybrid vehicles.

    Hybrid vehicles, as the name suggests, are powered by a combination of an internal combustion engine (ICE), alongside a ‘self-charging’ battery to power an internal electric motor. Plug-in hybrid vehicles operate in a very similar way, just with a larger battery that you can plug into an external power source to stay topped up.

    Servicing your hybrid/PHEV is just as, if not more, important than your conventional vehicle to keep the dual power source in good condition.

    So, let’s explore hybrid car maintenance, what sets a hybrid service apart from your regular service, the future of hybrid vehicles and everything in between. We’ve got a lot to get through, so it’s best we get started:

    UK hybrid car sales - The current market

    As we know, electric-powered vehicles are the future, but this can be a big change in habit for many – with drivers fearful over range, forgetting to charge up and the initial investment of an EV.

    However, with the rising prices of fuel across the UK, more drivers are considering alternative-powered vehicles. And that’s where hybrid technology comes in.

    Drivers in the UK are increasingly turning towards hybrid vehicles as a happy medium. They keep fuel costs down while ensuring peace of mind that during long distance drives, the standard engine will kick in once the electric starts to dwindle.

    According to research from Zap Map, 460,000 plug-in hybrid sales were reported in 2022. Similarly, the sales of hybrid vehicles increased by 40.6% from January 2022 to January 2023 – a strong start to the year. Drivers are clearly starting to see the advantage of making the switch, indicating that hybrid car industry growth is set to continue rising in 2023. And by 2040, the combined number of hybrid and electric cars could reach 25.5 million in the UK.

    How hybrid cars differ from standard cars with internal combustion engines

    So, you’ve taken the plunge and decided to get a hybrid, but now’s the time to get it serviced.

    Before we get into what goes on in a standard hybrid car service, it’s useful to understand what differentiates a hybrid car from your conventional petrol or diesel car.

    Hybrid cars offer a combination of a conventional ICE and an electric motor powered by a battery. Essentially, they’re a vehicle that uses more than one means of propulsion.

    Self-charging hybrid vehicles can’t be plugged in to charge the battery. Instead, the battery is powered utilising regenerative braking, which allows the vehicle to self-charge as you drive. All you need to do is get in the car and set off – no need to plug in to the power.

    On the other hand, plug-in hybrids recharge their battery pack by plugging a charging cable into an external power source, just like a fully-electric vehicle. More on PHEV car servicing later…

    Hybrid car advantages:

    • Better fuel economy
    • Lower CO2 emissions
    • Not reliant on EV charging stations

    Hybrids are perfect for town drivers, where you can run solely on electric power for short journeys with incredibly low running costs.

    Don’t worry about range either, the standard engine will kick in once the battery has been exhausted. And of course, you’ll be doing your bit to reduce your environmental impact when you’re running on electricity, too.

    Basically, hybrid cars contain all the benefits of an electric vehicle combined with the advantages of a standard combustion engine. Seems like a win-win, right?

    Hybrid car disadvantages:

    • Less horsepower
    • Expensive initial investment
    • Maintenance (You’ll need to find a specialist)

    As with anything, there’s always a few downsides. But in our eyes, these disadvantages are nothing major and the pros definitely outweigh the cons.

    So, because the power is split between the engine and battery, hybrid vehicles often don’t have the same kick behind them. Lower acceleration and less horsepower should be expected with a hybrid.

    Additionally, similar to an EV, the initial investment of a hybrid can be daunting. Thanks to the improved fuel economy however, hybrid vehicles are cheaper to run and should hopefully pay you back in the money saved on petrol in a few years.

    Sticking to money talk, hybrids can be slightly more expensive to maintain than your standard car – because of the dual power source. However, if you find a specialist – like the team here at Vasstech – you can take advantage of honest prices, friendly faces and trustworthy hybrid car servicing.

    Difference between a regular service and hybrid car servicing

    Due to the added complexity of the engine and electric motor, regular servicing is essential for keeping your hybrid (and its advanced technology) in check – ensuring you can detect any minor niggles before they become major problems.

    The usual servicing checks, like the tyres and brakes, alongside all the necessary filters, lubricants and ancillary parts to keep the combustion engine in working order still need fulfilling. But hybrid car maintenance doesn’t stop there.

    There are several additional checks that need to be carried out for a hybrid vehicle, all of which need a qualified technician to carry out to the best standards to keep your vehicle safe and sound. As we say, the hybrid car servicing requirements are a lot more complicated, with a lot more specialist bits and pieces to check over. Let’s take a look:

    PHEV and hybrid car servicing checklist

    Battery health

    Though your battery health is essential with any vehicle, batteries in a hybrid or PHEV vehicle take greater importance. Used to completely power the car when fuel is not in use, proper hybrid car servicing will require a thorough diagnostic health check of the battery to ensure everything is operating as it should. And of course, a replacement or repair if necessary. As a result, you can expect improved performance and efficiency from your vehicle.

    Inverter Coolant

    Taking a quick peek under the bonnet to ensure your hybrid doesn’t have any leaks is essential. Inverter coolant is different from engine coolant, so it’s an additional check that needs to be inspected during your service. It helps the car’s inverter turn the DC power (what comes from the batteries) into the AC power to make the electric motor work. This will be topped up as necessary during your service.

    Brake binding

    As we know, hybrid cars (as with electric vehicles) utilise a regenerative braking system. Simply put, regen braking is a nifty process that involves transforming the kinetic energy that would typically be wasted during braking and turning it into electricity. This energy is stored in the vehicle’s battery, and will be used when the car next accelerates – rather than draining the vehicle’s original energy supply.

    Though this system is brilliant for fuel economy, the extra work from the brakes opens the system up to a few extra problems – most commonly, brake binding. This is a niggly issue in which the brake pad sticks to the brake itself, causing the vehicle to slow down of its own accord. During your hybrid’s service, the technician will check for potential brake binding, repairing the issue if required.

    Charging port and high voltage cables

    Similar to an electric vehicle service, the charging port is incredibly important to keep in good check to ensure your vehicle’s charge is topped up and ready to go. This requires a skilled technician to complete properly, due to the high-voltage, intricate cables that make up a hybrid vehicle.

    Service intervals

    How frequently you should get your hybrid vehicle serviced should be the same as any other – whether it be a petrol, diesel or electric-powered vehicle. It’s widely recommended to bring your car in annually, or every 12,000 miles – whichever occurs first.

    However, if you’re always on the go, taking long road trips and big daily commutes to work, an interim service is recommended to account for your high mileage and stress on the brakes.

    Cost of servicing a hybrid car 

    Though the price shouldn’t differ too drastically from your traditional ICE vehicle, you may see a slight price bump due to the added complexity of two power sources. After all, the technician must be fully trained to work amongst high-voltage electricals, as well as possess the knowledge and skills to undergo a typical service.

    Our technicians have undergone extensive training to gain the qualifications necessary to fulfil your hybrid car servicing to the highest standards, so you know your car is safe, efficient and secure.

    All about plug-in hybrid vehicles

    Plug-in hybrid vehicles

    As we know, your battery is integral for keeping your PHEV working properly, and that means keeping your battery healthy. The best way to prevent excessive battery drainage is to not let it run completely flat time and time again, and to make sure to charge the battery at least once every fortnight. When charging, ensure all non-essential accessories – such as the aircon and any audio equipment is switched off.

    As stated earlier, checking the battery during servicing is integral, for both full hybrid cars and plug-in hybrids. Requiring a trained technician, it’s essential to take your PHEV in for regular servicing to keep everything running efficiently and effectively.

    Plug-in hybrid connectors

    Same as a fully-electric vehicle, your plug-in hybrid needs the right charging equipment. Most drivers will have a charging point installed at home, but EV charging infrastructure is rapidly becoming more accessible across the UK for those needing a charge on-the-go.

    Here’s the most common charging connectors for your hybrid:

    • Slow charging: 2 types of plugs, type 2 charges slightly faster because they have three additional wires to let the current run through.
    • Fast charging: CHAdeMO which allows charging up to 100 kW and CCS, allowing for a charging at a speed of up to 350 kW.

    Plug-in hybrid advantages:

    • Flexibility without range anxiety
    • Better fuel economy
    • An eco-friendly option

    You might be weighing up an electric car vs plug-in hybrid for your next vehicle. EVs aren’t for everyone, but plug-in hybrids strike the balance between improved fuel economy, environmentally-friendly driving and the easy, flexible aspect of a conventional car.

    Plug-in technology gives you far more control, meaning you’re not tied to charging points on a road trip. Most drivers will benefit from a PHEV on their daily commute, probably using solely electric power to get from A to B, but can enjoy the confidence that the normal engine will kick in on a longer journey.

    Realistically, plug-in hybrid vehicles are a great choice for those not quite ready to make the complete switch over to electric.

    Plug-in hybrid disadvantages:

    • Pricey initial investment
    • Reduced power
    • Need to remember to charge up

    The same as a standard self-charging hybrid vehicle, the main disadvantages of a PHEV is the expensive showroom cost and the reduced horsepower. However, with a PHEV, you’ll need to remember to charge up between uses to ensure you’re always ready to hit the roads.
