The likelihood of an EV running out of charge is relatively low. Modern EVs provide ample warnings through range displays and battery gauges. Navigation systems, including built-in sat-navs and apps like Google Maps and Zap Map, can guide drivers to the nearest charging point. Additionally, most electric cars feature integrated de-powering systems that reduce power and speed when the battery is low, helping drivers reach a charging station.
Towing Electric Vehicles
Towing an EV isn’t straightforward. Many electric cars cannot be towed with a rope or bar due to their electric motors’ connection to the wheels and the absence of a neutral gear. Some EV’s have a tow mode, but generally, they need to be transported on a flatbed trailer. Alternatively, some can be towed using a dolly, where the front wheels are lifted off the ground.
What Happens If an EV Battery Runs Flat?
Due to the rise of EV’s Breakdown Recovery has adapted. For instance, RAC vans are now equipped with lightweight 5kW chargers, providing a 10-mile boost to help drivers to get to the nearest charging point. This service is handy if a driver encounters a faulty charger or runs out of charge unexpectedly. These portable chargers are powered by a secondary alternator in the patrol van, allowing a quick top-up without carrying heavy batteries.
Can You Jump-Start an Electric Car?
Yes, you can jump-start an electric car, though it’s rarely needed. Most EVs have two batteries: a large lithium-ion battery for driving and a traditional 12-volt battery for accessories and starting the vehicle. The 12-volt battery can be jump-started similarly to those in petrol or diesel cars. However, you must use a petrol or diesel vehicle for the jump-start, not another EV, and ensure your EV isn’t plugged in during the process.
To jump-start an electric car:
- Locate the 12-volt battery, typically under the bonnet or in the boot.
- Use a jump lead to connect one end to the positive terminal on the EV’s 12-volt battery and the other end to the positive terminal on the assisting vehicle.
- Attach the second lead to the negative terminal of the assisting vehicle and the other end to a grounded part of the EV’s bodywork.
- Start the assisting vehicle, and turn the EV on to its ‘ready’ mode.
- Once the EV starts, in reverse order disconnect the cables.
Keep the EV running for about 15 minutes or take it for a short drive to ensure the 12-volt battery recharges. A battery booster pack can also be used as an alternative.
Flat battery prevention
Inactivity for extended periods can lead to a flat battery, especially in electric vans, as noted by the Association of Fleet Professionals (AFL). To prevent this, consider using a trickle charger if the vehicle will be idle for a while. This device maintains the battery charge, avoiding one of the most common reasons for EV call-outs. Regular use will keep the 12 volt battery in good condition as well as longer trips.
Conclusion
While running out of battery charge in an EV can be more challenging than in traditional vehicles, modern technology and services significantly mitigate this risk. With proper care and attention to charging and battery maintenance, the chances of being stranded are minimal. Understanding these aspects ensures a smoother, more reliable EV driving experience.
