Widespread alarmist myth concerning electric motorcycles and electric mobility in general, that's what predicts a dark future, of continuous blackouts.
This concern – understandable, but up to a point – is based on fear that the electricity grid will not be able to support the excessive load of connected vehicles and that the consequence is blackouts that leave us all without electricity.
Recently I was surprised to hear it even from an engineer friend. Orphan! At that, having esteem of his opinions, I asked him if he could please give me data on the matter. So I found out that… he had none. His was a hypothesis and not a thesis, it wasn't even thorough with some research! Just enough to panic. The things, fortunately for us, they should stay a little bit’ diverso, let's see it.
Surely a sudden boom in electric vehicles connected to the grid could lead to failures, but… In the first place we will not witness a sudden boom as for a progressive diffusion and secondly not all vehicles will all be recharged at the same time.
But let's take some practical examples: in Norway electric cars are already the 21% of the park in circulation and nothing has happened yet. Nulla! In 2030 it is expected that in the country of the fjords will circulate 1,5 millions of electric cars. According to the same study electricity demand will only grow by 3%.
Two aspects need to be considered. The first concerns network development: the energy mix is getting better with a increase in renewable sources and hand in hand the energy efficiency of household appliances and homes has grown. Ovvero, there is less waste. It is also improving there’energy storage, the reserve of energy to use at peak times.
The second aspect, instead, concerns the so-called tecnologia di ricarica bidirezionale. Ovvero la batteria del veicolo non riceve soltanto corrente dalla rete ma è in grado anche di restituirla alla rete o a un altro veicolo. Così le auto non saranno semplicemente parcheggiate in ricarica, ma saranno “vehicle to grid” e sfrutteranno il fatto di rimanersene ferme per tanto tempo, cosa che già innegabilmente fanno. Non è ancora il caso della moto elettrica, ma nell’auto è già possibile. Questo argomento aprirebbe ad altri, per primo sull’utilizzo stesso dell’auto, sulla condivisione, sulla congestione del traffico: abbiamo veramente bisogno tutti di possedere un’auto? Ma non usciamo dal nostro seminato e pensiamo alla nostra moto elettrica, il cui assorbimento attaccata alla 220v è di circa 1 kWh. Più o meno come qualsiasi elettrodomestico.
