I’m going to tell you a little anecdote about what moves behind some texts. For a time, it became fashionable among car brands to put a coffee maker in presentations to show us the advantages of technology. V2L or Vehicle to Loadin English.
Most of the cars electric and some plug-in hybrids They already have it. It is the possibility of using the electric car battery as an energy store to charge our devices. To demonstrate this in the presentations, we have seen everything as we said: coffee makers, electric bicycles, lighting systems with small bulbs to decorate some spaces…
Honestly, it’s usually something I mentioned in passing in the texts because I didn’t see much use in it. Who makes a capsule coffee on the road or in the middle of the field? Who prefers to eat up the range of their car to recharge the battery of their electric bicycle instead of carrying it already charged from home?
But in China they are showing that the system has much more interest than we can think. In fact, we ourselves have been able to see it, still in a limited way, during the general blackout last year. Now, floods in the Asian country are showing us how useful it is.
Your cell phone always ready in an emergency situation
Last April 2025, when Spain’s general network was off, a lucky few were able to eat hot, keep the refrigerator cool, and keep their mobile phone ready. They were the owners of electric cars.
Some of them then saw that this function that the commercial had sold them and to which they had not paid much attention, finally, served something really useful. Luckily, our discomfort lasted only a few hours but it made clear to us some added advantages of having an electric car.
But when your country has filled the streets with this type of vehicle and you suffer real problems, the electric car can become a saving rolling battery.
In the Guangxi region have suffered historic rains by the action of a typhoon called Mesaak. Many have been left completely stranded in the middle of the water. We have seen how the drones used for food delivery They helped those who fled from the water in the upper part of their homes. Or even those who have used their “floating” cars to rescue those affected. To the point that since BYD they have had to remember that these cars cannot be used as emergency services.
But in addition to these uses, having a multitude of NEV cars (as China calls the category that includes plug-in hybrids and electric cars) has proven to be a perfect opportunity for dozens of people to keep in touch with their families and the emergency services.
Media like Southern Metropolis Daily either Shanghai Daily They have published some images on Weibo that show how people crowd next to cars because a single vehicle can charge dozens of mobile phones or portable batteries. This is possible because cars that have V2L technology can charge external devices using alternating current.
In this case, what they have done is remove the socket from the vehicle and plug it into a multiple-input power strip to increase the number of phones that can be charged. The result is rolling batteries that keep the phones of dozens of people in a risk situation active.
Of course, as explained in CarNewsChinait is important to be clear that this is not the most recommended practice and that multiplying the energy output by connecting power strips together can cause damage to them and, therefore, to the devices.
The most striking thing is that, in the cars we see in Europe, bidirectional charging is usually limited to about 3.6 kW in many cases. However, in the CNC They point out that this is a rarity in China and is only available on lower-end cars. On the contrary, most cars have much higher charging capacities when they have to power other devices and even mention a Geely pick-up called Riddara RD6 which is capable of charging up to a power of 36 kW because it can carry a drone on its back.
