What to Do When an Electric Vehicle Runs Out of Power Midway?

Previously, we discussed the difference between NEDC range and actual driving range. When it comes to fuel-powered vehicles, the discrepancy between tested and actual range isn't significant, and fuel cars can be refueled anytime. In contrast, electric vehicles (EVs) rely entirely on motors powered by batteries. The range tested under NEDC conditions often differs greatly from the actual range due to the limitations of current battery technology. EVs also face issues like range degradation and environmental sensitivity, leading to "range anxiety."

What to Do When an Electric Vehicle Runs Out of Power Midway?

Despite continuous advancements in EV technology, the fundamental properties of batteries haven't changed. Many owners hope for improvements with solid-state batteries, but even the mass production of semi-solid-state batteries is challenging with current technology. Addressing range anxiety requires a different approach. For example, Mercedes-Benz has introduced the EQXX concept car with a range of 1202km, but it’s not ready for mass production and is unaffordable for most people. Therefore, improving terminal equipment, battery capacity, and charging speed are crucial.

In small cities like mine, the number of proprietary charging stations, battery swap stations, and commercial charging stations by new car manufacturers is limited. Most EV owners install home charging stations to alleviate range anxiety, primarily due to overstated range claims. NEDC range tests serve only as a reference, and EVs often run out of power unexpectedly, especially in extreme temperatures, where the actual range can significantly differ.

In summer, high temperatures can cause EVs to overheat, and vehicles with low-quality batteries may catch fire. In winter, EVs face even more challenges: cold temperatures can drastically shorten their range, prevent fast charging below 0°C, and prohibit charging at -15°C, restricting normal use. Additionally, EV speed and power consumption are directly proportional, with a noticeable difference between city and highway driving ranges. If an EV runs out of power midway, remember these four tips—especially the creative fourth one!

1. Call for Insurance Assistance

Both EV and traditional car owners purchase insurance before hitting the road. Many opt for a variety of commercial insurance plans to meet different needs, including coverage for accidents and several or unlimited free towing services. If you run out of power on the highway, call your insurance company's emergency assistance.

It’s worth choosing a reliable insurance company with a strong reputation, as their services are usually more effective. Though lesser-known insurers might offer lower premiums, their service quality often doesn’t measure up.

2. Call for Mobile Charging

Most major EV manufacturers provide roadside assistance, including towing and charging services. These service vehicles usually carry high-power generators and fast-charging technology, allowing them to charge your car in a few minutes, sufficient to exit the highway or reach a service area.

3. Maintain the Most Efficient Speed and Exit the Highway

What’s the most energy-efficient speed? It varies, especially for fuel cars, which generally achieve optimal fuel efficiency around 100 km/h. For EVs, higher speeds mean higher energy consumption, and around 40 km/h is typically the most efficient. If you notice your range depleting quickly, maintain this speed and exit the highway at the nearest opportunity.

4. Carry a Generator

This might sound funny, but it’s a real experience from a friend. During a trip this National Day holiday, my friend bought a generator for his EV, which proved extremely useful during traffic jams and camping, providing timely recharges.

The first two methods involve external assistance, meaning you’ll need to wait, so remember parking regulations. The fourth tip, however, is highly practical, and many owners find it worth emulating. What’s your take on this?
