Home charging

What home charger do I need?

Your car, daily driving and time at home.

Car starting values

Model buttons fill consumption, battery and AC limits. Your driving and home supply stay in place. These are editable examples for the stated generation; check the exact version of your car.

Default consumption is the mean of the site’s collected owner reports, not a representative Bulgarian fleet average. Battery capacity is an editable version example. Other EV starts at an illustrative 20 kWh/100 km with unconfirmed AC limits.

The electricity default is the mean of the three suppliers’ night tariffs, including VAT and network fees. Adjust it for your provider and any daytime charging.

Ways to charge at home

These choices fill an example charging speed. They do not confirm that your home can supply it. A garage socket here means a rated industrial socket, not an ordinary socket moved to the garage.

  • Ordinary socket: 2.3 kW · 1 × 10 A
  • Dedicated garage socket: 3.68 kW · 1 × 16 A
  • Wall charger: 7.36 kW · 1 × 32 A
  • Three-phase wall charger: 11.04 kW · 3 × 16 A

Low daily energy demand does not prove a socket or cable is safe for sustained charging. An electrician must check the circuit, earthing, protection, connections and available capacity.

What runs while the car charges?

Appliances and charging

Select what may run at the same time, not everything you own. Lights, a fridge and small appliances are already included. Each choice reserves an illustrative allowance for the full charging window; thermostats and programmes may draw less in practice.

  • Lights, fridge and small appliances only: 0.5 kW
  • Water heater: 2 kW
  • Oven / hob: 2 kW
  • Air conditioner: 1 kW
  • Tumble dryer: 1 kW

These are planning allowances, not measured appliance ratings or household averages. Use the detailed settings for your actual simultaneous load. Appliance choices replace any measured phase loads or timed load profile.

To calculate how much is left for the car, we also need your home supply details. Until then, charging times are estimates without a confirmed home limit.

Lights, fridge and small appliances only

To check the appliances together, add your home supply in detailed settings.

Car and consumption

Vehicle market

Imported cars need their actual AC configuration checked; a connector adapter does not change the onboard charger.

Charging efficiency

90% is an editable planning assumption. ADAC measured higher losses at a domestic socket than at an 11 kW wallbox. Cold weather and the exact car can change them.

Winter multiplier

A multiplier of 1 leaves your consumption unchanged. For example, 1.25 adds 25%. This is your planning assumption, not a weather forecast.

Home capacity and charger

Home electricity supply

If you do not know, the result still estimates the charger power your driving needs. Available home capacity remains unknown. A three-phase charger does not make a single-phase car charge on three phases.

Main breaker

Read the main breaker rating for the whole home, not a socket breaker. On three-phase supplies this is the current per phase. Contracted power and uneven phase loads may lower the available capacity.

Load management

Dynamic balancing can reduce charging when household use rises. It needs compatible equipment and a correctly configured installation. Without a timed load profile, this calculation keeps the same household allowance.
