Can I charge another electric car using the V2L system?
Can the V2L system included in an electric car be used to charge a second one? Cesare asks, and Vasielettrico responds. To contact us: info@vaielettrico.it.
“I’m one of your readers and I really appreciate your editorial approach. I increasingly see the V2L system listed in the technical specifications of many EVs. Is it possible to charge another electric car using this system?” Cesare Agnello
Answer – Technically yes. In reality, it only makes sense in emergency situations. In fact, the transfer of electricity from one vehicle to another is slow; energy losses are significant; the process requires a cumbersome procedure; compatible devices are needed.
The electric vehicle equipped with a V2L (Vehicle to Load) system delivers power through an adapter cable with a shuko plug (photo above left). The portable charger, known as a “carichino” (see photo above right), that comes with the second vehicle must be connected to this plug. In essence, the vehicle supplying power functions like a 230 Volt electrical outlet, powering the charger connected to the second vehicle. However, it is necessary to ensure that the V2L system is compatible with the electrical specifications of the portable charger, particularly regarding grounding and differential protections.
The available power ranges from 2.3 to 3.6 kW, depending on the vehicle model equipped with V2L. Thus, in one hour, at most just over 3 kW can be transferred, after accounting for conversion losses equivalent to a range loss of 10-15 km. This can be useful for reaching the nearest charging station or fixed power outlet, but not much more.
And naturally, the energy transferred is drawn from the battery of the car acting as the generator.
