What are the pros and cons of charging your Tesla at home?


The most convenient way to charge your EV is to charge it at home overnight while you sleep. Home chargers tend to be slow chargers which reach around 3.6 - 7 kW, although you can also charge using your home’s plug sockets which charge at speeds of around 2.3 kW. 

Pros
Charging your Tesla Model Y at home overnight is probably the cheapest, most cost-efficient way to charge your EV. This is because off-peak energy prices are significantly cheaper than peak charging. Model Ys come with an adapter wire, allowing you to charge your EV using your home's plugs easily. 

If you're interested in charging at home, installing a home charging unit could be worth your time. Over time this could save you money. There are grants available to help you afford a home charger. 

The OZEV Chargepoint Grant is up to £350 or 75% off the fully installed charge point cost if specifics are met. There is also the Scottish EST Domestic Chargepoint Grant which gives you up to £300 and can be used alongside the OZEV Chargepoint Grant.

Cons
Home chargers rarely exceed speeds of 7 kW. This means charging the Tesla Model Y's large battery would take a long time. If you don't invest in a home charging station, it might also be risky to home charge as the 3-pin plug can damage your home's wiring. 

If you choose to charge during the day, it can also get quite expensive and may not compare favourably with public charging stations, despite being much slower.
