# How Safe Are Electric Cars? By EV Charge Cables ยท Published 18 October 2026 **The short version** Electric cars are generally very safe, performing well in crash tests and built with multiple layers of electrical protection for drivers and pedestrians. - EVs typically score well in Euro NCAP testing and have a low centre of gravity due to floor-mounted batteries - High-voltage components are sealed to high ingress protection standards, making them safe to drive and charge in the rain - New EVs sold in the UK since 2021 must have an Acoustic Vehicle Alerting System (AVAS) to warn pedestrians at low speeds Electric cars are, by most measures, very safe vehicles. They consistently perform well in Euro NCAP crash testing, benefit from a low centre of gravity thanks to their floor-mounted battery packs, and are engineered with multiple layers of electrical safety protection. If you are considering switching to an EV, safety is one area where you are unlikely to be disappointed.

Electric cars generally perform very well in Euro NCAP crash testing, often achieving high star ratings. A key structural advantage is the large battery pack mounted flat under the floor. This lowers the car's centre of gravity considerably compared with a petrol car, which reduces the risk of rollovers in severe manoeuvres. The battery enclosure also adds structural rigidity to the floor, and manufacturers design crumple zones specifically around it. That said, crash performance varies by model, so always check the Euro NCAP result for the specific car you are buying at euroncap.com rather than assuming all EVs score identically. ### Is it safe to drive or charge an electric car in the rain? Yes. Electric cars are designed and tested to operate safely in wet weather. The high-voltage battery, motor, and charging components are all sealed to high ingress protection standards, and the systems are engineered to isolate the electrical supply if a fault is detected. You can charge your car in the rain without worry, whether you are using a home wallbox, a public charger, or a [portable charger](https://www.evchargecable.co.uk/portable-ev-chargers). The one caveat that applies to all cars, electric or petrol, is to avoid driving through deep standing water, as flooding can cause serious damage and create genuine hazards. Always check your owner's handbook for the manufacturer's specific guidance on water ingress ratings, as these vary between models. ### What happens to the battery in a crash or extreme heat? Modern EV batteries are managed by a Battery Management System (BMS) that monitors temperature, voltage, and current in real time. If the BMS detects an abnormal condition, it can limit charging, reduce power output, or shut the system down to prevent damage. In a collision, the car's safety systems are designed to disconnect the high-voltage system to reduce risk. Manufacturers also build in physical protection around the battery pack, such as reinforced casings and underbody shielding. If a battery is seriously damaged in a crash, it can potentially enter thermal runaway, but modern designs include cooling circuits and fire-resistant materials specifically to reduce that risk. ### Do electric cars make enough noise to be safe for pedestrians? This was a genuine concern in the early days of EVs, which are much quieter than petrol cars at low speeds. The EU and UK addressed it by requiring all new electric and hybrid cars sold from July 2021 onwards to be fitted with an Acoustic Vehicle Alerting System (AVAS). This emits a sound at speeds up to around 20 km/h to alert pedestrians and cyclists. If you are buying a used EV built before this regulation took effect, it is worth confirming whether AVAS was fitted as standard or as an option, particularly if the car is often used in pedestrian-heavy areas. ### What should I know about regenerative braking as a new EV driver? Regenerative braking is one of the most noticeable differences for new EV drivers. When you lift off the accelerator, the motor acts as a generator and slows the car, recovering energy back into the battery. In stronger regen modes, this can feel quite abrupt at first. Most EVs let you adjust the regen strength, and some offer a very light setting that mimics a conventional car's coast. From a safety perspective, the braking itself is entirely normal once you are used to it. The main adjustment period is learning how much deceleration to expect when you lift off, so practice in a quiet environment before driving in heavy traffic. ### Are there any long-term safety concerns with owning an EV? Long-term, the main areas that sometimes worry prospective EV owners are battery degradation and software reliability. Battery capacity does reduce gradually over time, but this affects range rather than safety. Manufacturers typically offer a battery warranty for a set number of years or miles, so check that for the model you are considering. Software updates are also a feature of modern EVs and can improve safety systems over time, but it is worth understanding what your car's update process involves. In general, EVs have fewer moving parts than petrol cars, which removes many traditional mechanical failure points. ### Frequently asked questions #### Can you get an electric shock from an EV? The high-voltage system in an EV is fully sealed and isolated from the vehicle bodywork. Under normal circumstances, you cannot receive a shock from touching the car. In the event of a serious collision, the safety systems are designed to disconnect the high-voltage circuit automatically. Always leave accident investigation to trained emergency responders. #### Is it safe to charge an electric car in a garage? Yes, for most home wallbox and slow charging situations. Ensure there is reasonable ventilation, as some small amount of hydrogen gas can be released from certain battery types during charging, though modern lithium-ion packs produce very little. Do not charge a car with a damaged battery in an enclosed space, and always follow the manufacturer's guidance. #### Do EVs have a higher risk of catching fire than petrol cars? Available data generally suggests EV fires are less frequent per vehicle than petrol car fires. However, when an EV battery does catch fire it burns intensely and for a long time, which is challenging for fire services. Following safe charging habits and using approved cables and equipment significantly reduces the risk. #### Are electric cars safe for children? Yes. Child car seat fitting works the same way as in a conventional car, using standard ISOFIX anchor points. The crash safety standards and Euro NCAP testing that apply to EVs cover occupant protection for all ages. The quieter cabin can actually be a comfort benefit for young children on longer journeys. #### What should I do if my EV is in a flood? Do not attempt to drive through deep standing water. If your EV has been submerged, do not try to charge or drive it until it has been inspected by a qualified technician. Contact your manufacturer's roadside assistance and your insurer. High-voltage components and flood damage are a combination that requires professional assessment before the car is used again. #### Does regenerative braking cause any safety problems? No, but it does require a short adjustment period. In strong regen modes, brake lights may not always illuminate when you are slowing using regenerative braking alone, though many manufacturers are now programming the lights to activate in this situation. Check your car's settings and owner's manual to understand how yours behaves. Electric cars are engineered with safety as a core consideration, not an afterthought, and they hold up well against petrol cars on most measures.
