What Changes Inside an Electric Car — And What Accessories Help
CarMoods TeamBuying an EV changes more than what's under the bonnet. The cabin itself works differently: a touchscreen replaces half your buttons, the key fob might not even leave your pocket, and a glass roof the size of a dinner table turns your car into a small greenhouse on a hot Australian afternoon. None of this is covered in the brochure, and most owners discover it by trial and error in the first few months. A well-chosen set of interior accessories deals with most of it before it becomes an annoyance you just live with.
This isn't a checklist of what to buy first — that's our new EV owner checklist. This is about the specific ways an EV cabin behaves differently to a petrol car, and the accessories that exist because of it.
The touchscreen becomes the dashboard
In most EVs, climate control, drive settings, mirror adjustment and even the glovebox release have moved off physical switches and onto one glass panel, often 30cm or more across the diagonal. That panel is now the single most-touched surface in the car, and it shows: fingerprints, watch scuffs and fine grit scratches quickly dull the glass and soften the glare-reducing coating applied at the factory.
A tempered glass overlay protects that factory coating rather than replacing it, which matters because oleophobic (fingerprint-resistant) coatings are expensive to reapply and cheap to protect. Choose a cut that matches your specific screen rather than a universal sheet — misalignment at the edge just lets dust sit directly against the glass. Tesla owners have the widest range of model-specific cuts available; browse the full Tesla accessories range for your exact screen generation.

Cameras do a mirror's job now
The same logic applies to the cameras dotted around the body. Reversing cameras, 360-degree surround view and lane-keeping systems all rely on small lenses exposed to road grime, insect strikes and stone chips. A scratched or fogged lens degrades parking guidelines and driver-assist accuracy, which matters more in a car that leans on cameras instead of a full set of mirrors. A clear, low-profile lens cover is a cheap way to protect a sensor that's fiddly and expensive to replace.
If your EV has a large secondary screen for navigation, common on newer Chinese and Korean-brand SUVs, the same glass-protection principle applies there too, sized to that panel rather than a generic fit.
Glass roofs turn the cabin into a greenhouse
Panoramic glass roofs and larger windscreens are common across newer EVs, partly for cabin light and partly because there's no engine bay eating into the proportions. The trade-off is heat: a parked car in direct Australian summer sun can reach cabin temperatures of 60°C or more within an hour, and a full-glass roof accelerates that, since there's simply more glass area for radiant heat to pass through. Tint film alone doesn't stop it — most of that heat transfer happens through infrared wavelengths basic tints barely touch. BYD's Seal, Atto 3 and Dolphin all ship with large glass areas, and the BYD accessories range has shades cut specifically for each model's roof and screen.
That heat also accelerates UV breakdown of dashboard plastics and stitching, and pushes cabin electronics — including the touchscreen you just protected — through more thermal cycling than they're rated for. A reflective windscreen sunshade, sized to the actual glass rather than a generic fold-out, is the simplest fix, and pairing it with a roof-specific shade stops heat build-up from both directions at once.
Wireless charging and phone-as-key change the getting-in ritual
Plenty of EVs now use your phone as the primary key, over Bluetooth or NFC, which means your phone needs to be charged, awake and within reach the moment you walk up to the car. That's shifted phone mounts from a nice-to-have to something closer to essential, and it's why cup-holder and vent-mounted wireless pads have become common EV-specific accessories rather than generic add-ons.
The catch is heat: fast wireless charging generates more warmth at the coil than a cable ever does, and a mount without proper grip lets the phone shift out of alignment, dropping charging speed and generating even more heat for less power delivered. Our wireless charging mount guide covers this in detail — in short, auto-clamping mounts with active alignment outperform flat pads for anything beyond a top-up.

Keyless entry opens a new theft risk
Passive keyless entry, standard on most EVs, works by constantly listening for a signal from your key fob or phone within a short range. That convenience is also its weakness: relay theft uses a pair of small devices to capture the fob's signal from inside your house and rebroadcast it next to the car, tricking it into thinking the key is present. It's a real, increasingly common method, not a rare edge case, and it works on any car with passive keyless entry — EV or not.
A signal-blocking pouch or box stops the fob's signal being picked up when it's not in use. It's a two-second habit — the key goes in the box at home — that closes off the whole attack rather than relying on the car's own security to catch it.

Your digital key card needs protecting too
Some EVs, Tesla included, pair the phone key with a backup NFC card the size of a credit card, meant to live in your wallet as a fallback. It's easy to treat casually because it looks like any other card, but it's the one thing that gets you driving if your phone dies or the app won't connect. A dedicated case keeps it separate from other cards so it doesn't get scratched or bent, and stops the internal chip degrading from being crushed in a tight wallet.

Rear-seat tech and a near-silent cabin
Without an engine idling nearby, an EV cabin is quiet enough that things you'd never notice in a petrol car — a rattling coin in the door pocket, wind noise around a phone mount, the whirr of the climate fan — suddenly stand out. It also means rear passengers hear everything from the front seats, part of why rear-seat entertainment and organisation have become common EV-specific purchases rather than an afterthought.
A tablet holder clipped to the back of the front seat keeps a device stable without the passenger bracing it, and it's worth pairing with ambient lighting so the back seat doesn't rely on front cabin lights spilling over. Neither is EV-exclusive, but both get used more once road and engine noise stop masking everything else in the cabin.
Sealed cabins trap more than warmth
EV bodies are typically sealed tighter than petrol equivalents, partly for aerodynamics and partly because there's no exhaust or engine-bay ventilation drawing air through the gaps a combustion car relies on. That keeps road noise and dust out, but it also means cabin air recirculates more and clears more slowly — odours from spilled coffee, wet gym gear or a dog on the back seat linger longer than they would with more natural airflow.
A compact cabin air purifier running off a 12V socket helps here, filtering particulates and reducing odour build-up between trips rather than masking it — a different job to an air freshener, which adds scent but does nothing about the air quality causing the smell.

Protecting the interior — and what V2L means for you
Regenerative braking means an EV's brake pads and rotors work far less than a petrol car's, and most owners settle into a driving style that uses the accelerator to slow down as much as the brake pedal. It's a change in habit rather than an accessory decision, but it does mean less brake dust reaching your floor mats and seats over time. A full set of seat covers is still worth having for spills, pets and general wear, just for different reasons than in a petrol car.
Separately, a growing number of EVs support Vehicle-to-Load (V2L), letting the main battery power external devices through an adapter rather than only driving the wheels. A Type 2 V2L adapter rated around 3.5kW can run power tools, camping gear or a household appliance during a blackout — a genuinely new use case a petrol car's 12V socket was never built for. Our guide to car power sockets and inverters covers the broader topic, including inverters and V2L.
Frequently Asked Questions
1. Do I really need a screen protector on an EV's touchscreen?
It's not compulsory, but the coatings manufacturers apply to reduce glare and fingerprints wear off with daily use, and replacing the screen itself is far more expensive than a fitted glass overlay. It's one of the cheapest ways to protect a component the whole cabin now depends on.
2. Does tinting the windows stop the heat from a glass roof?
Only partly. Standard window tint mainly blocks visible light and some UV, but a large share of the heat coming through a glass roof arrives as infrared radiation, which basic tints don't stop well. A reflective shade fitted to the glass itself blocks heat before it enters the cabin, which is more effective than tint alone.
3. Is relay theft actually common, or is it overhyped?
It's a well-documented method used against any car with passive keyless entry, not just EVs, and it doesn't require breaking into the car or defeating an alarm — it simply tricks the car into thinking the key is nearby. A signal-blocking pouch or box is a low-cost way to remove the risk entirely rather than hoping it doesn't happen to you.
4. Why does my EV cabin feel stuffier than my old petrol car?
EV bodies are usually sealed more tightly for aerodynamic efficiency, and there's no engine-bay airflow drawing outside air through incidental gaps the way there is in a combustion car. That means cabin air recirculates more and clears odours more slowly, which is where a compact cabin air purifier earns its keep.
5. What can I actually do with V2L power in an EV?
A Type 2 V2L adapter turns your car's battery into a portable power source, typically supplying around 3.5kW — enough for camping gear, power tools on a job site, or essential appliances during a home power outage. It's a capability petrol cars simply don't have through their 12V socket.
An EV's cabin isn't just a quieter petrol car — the touchscreen takes on more jobs, the glass lets in more heat, the key works differently, and the whole thing is sealed and wired in ways that create new problems and new capabilities. None of the fixes above are complicated, but knowing which apply to your car saves a lot of trial and error in the first year. Browse the full range of interior accessories to fit your EV.
