Just by way of a quick example. An “executive” block of flats, In a Northern city, had underground parking allocated parking bays. Several residents wanted ev chargepoints for their electric cars. First problem you face is that the Supplies flats were designed With the standard design engineers loading assessments. The extra additional loading wasn’t foreseen 20 years ago. However, a dedicated supply is always an option into a separate Industrial fuse unit. Thats good for 300 amps per phase. However, will the low voltage network stand that additional load. Below is an excerpt from westernpowers ev initiative. The “intervention” Quoted will be mind numbing. A logistical nightmare. Trickle charge at 10 amps overnight is the best way.
“Electric Nation, the world’s largest domestic electric vehicle (EV) trial, is revolutionising domestic plug-in vehicle charging. By engaging 500-700 plug-in vehicle drivers in trials, the project is answering the challenge that when local electricity networks have 40% - 70% of households with electric vehicles, it is estimated that at least 32% of these networks across Britain will require intervention.”
