An owner asks for the fastest home charger available. He is quoted for a larger unit, has the supply assessed, and after installation discovers his car charges at exactly the same rate it did before.
His vehicle accepts a lower rate. The charger is capable of more and the car will never ask for it.
Myth 1: the charger determines the speed
Reality: the slowest link determines it. The unit, the property's supply and the car's own onboard limit, and for most home installations the car is the constraint.
Myth 2: a bigger unit is always better
Reality: it is only better if the vehicle can use it. Selling somebody capacity their car cannot accept is how a trustworthy installer becomes a disappointing one.
Myth 3: home charging should be fast
Reality: it should be sufficient overnight, which is a different requirement. Rapid charging belongs on a motorway, and home charging belongs to the hours the car is parked anyway.
Myth 4: owners need to fill the battery every night
Reality: most daily mileage replaces in a few hours. Explaining that typical use needs a fraction of an overnight window reframes the whole question.
Myth 5: the advertised figure is what you get
Reality: charging slows as a battery fills, temperature affects it and the final portion takes longer. Real world figures are lower than the arithmetic suggests.
Myth 6: three phase is the answer
Reality: most domestic properties have a single phase supply, and a three phase installation is a significant undertaking. Say plainly when it is and is not a realistic option.
Myth 7: speed matters more than scheduling
Reality: charging at the right time usually matters more than charging quickly. A slower charge overnight on a suitable tariff beats a faster one at the wrong hour.
Myth 8: load management slows everything down
Reality: it adjusts charging to stay within the available supply, usually overnight when nothing else is running. Most owners never notice it and it avoids a supply upgrade.
Explain the vehicle limit before quoting
Ask the make and model and explain what it accepts. It occasionally costs an upsell and it always builds the reputation that brings referrals.
Publish a realistic charging table
By vehicle type and daily mileage, showing hours required. Owners can then see that their requirement is comfortably met.
Explain what happens with two cars
Whether they charge simultaneously, how the supply is shared and what that does to speed. Households with two vehicles need the arithmetic.
Explain the battery health question
That manufacturers publish their own guidance about charging habits and that slower charging at home is generally unremarkable. Point to the source rather than claiming.
Connect it to the supply assessment
Because the property's capacity is the other constraint, as in home charger installation questions before a survey and home EV charger installation enquiries and survey details.
Answer the speed question honestly at any hour
New owners research this in the evening, which is the availability argument in an AI chatbot for electricians, alongside the rest of EV charger installation questions homeowners ask.
