EV Charger Installation

Many new EV owners go home with two things: a new car and a simple charging cable that plugs into a regular outlet. Then someone mentions a Level 2 wallbox, and the questions start:   Do I really need Level 2, or is the basic cable enough?If I spend the money now, will it actually change my daily life?   If you still feel shaky about the difference between Level 1, Level 2 and DC fast charging in general, it helps to read a full overview of EV charging levels first, then come back to this home-charging decision.     What really changes between Level 1 and Level 2 at home Level 1 home charging Level 1 uses a standard household outlet, typically 120 V in North America. Power is usually around 1–1.9 kW. For many EVs this works out to roughly 3–5 miles (5–8 km) of range added per hour.   It is slow, but simple. You plug in at night, unplug in the morning, and the battery slowly climbs while you sleep. For light daily use, that can be enough.   Level 2 home charging Level 2 uses a dedicated 240 V circuit and an AC EVSE or wallbox. Power typically ranges from about 3.7 kW up to 7.4, 9.6 or 11 kW, depending on the home wiring and the car’s onboard charger.   At these levels, many cars gain 15–35 miles (25–55 km) of range per hour. One evening can refill what you used over a busy day. An overnight session can restore several days of commuting.   How the experience feels different The change between Level 1 and Level 2 shows up in habits: • How many hours you need plugged in to replace a day of driving • Whether you can skip a night of charging and still feel relaxed • How often you rely on public charging to catch up   With Level 1, charging is a slow, steady background drip. With Level 2, charging has more “punch”; a few evening hours can do what used to take most of the night.     Charging speed: Level 1 vs Level 2 Before you choose, look at how power turns into range and time. The table below uses a mid-size EV with a battery around 60 kWh as a reference. Numbers are rounded to show the pattern, not exact for every model.   Home charging options compared Home charging option Typical power Range added per hour (approx.) Time from 20% to 80% (approx.) Typical use case Level 1 (standard outlet) 1.4–1.9 kW 3–5 miles / 5–8 km 20–30 hours Very light use, backup, second car Moderate Level 2 wallbox 3.7–4.6 kW 12–18 miles / 20–30 km 8–12 hours Modest commutes, long nightly parking Common Level 2 home wallbox 7.2–7.4 kW 25–30 miles / 40–50 km 4–6 hours Main family car, mixed city and highway driving   Two quick examples: About 30 miles (50 km) a day • Level 1: roughly 6–10 hours of plug-in time to get that back. • 7.4 kW Level 2: about 1–2 hours is enough.     About 70–80 miles (110–130 km) a day • Level 1: may need more than one long night to catch up from a low state of charge. • Level 2: can comfortably recover that distance overnight, even if you start charging late.   If your daily driving is short and predictable, Level 1 can keep up. The more mileage and variation you have, the more useful Level 2 becomes. Installation, panel capacity and cost: what changes with each level   Using Level 1 every day A plug-in cable in a wall socket is convenient, but for long-term daily use it is worth having an electrician check a few points: • The outlet should be in good condition, not cracked or discolored • The wiring should be suitable for continuous load at the chosen current • The circuit should not also feed several other heavy appliances   Long extension cords, coiled leads and multi-plug adapters are not ideal for EV charging. They add resistance and heat, especially over many hours. If the socket is far from the parking spot, a dedicated outlet or charging point is a safer plan than a chain of adapters.   Installing Level 2 at home Level 2 needs more planning, but the process is straightforward when the basics are in place: • A 240 V circuit with the right breaker size in the panel • Cable sized correctly for the distance to the parking spot • A safe mounting position for the wallbox indoors or outdoors • Permits and inspection, where local rules require them   An electrician can tell you whether there is spare capacity in the panel, how complex the cable route will be, and whether load management is needed so that the charger reduces power when the home is using a lot of electricity elsewhere.     Older homes and tight panels In older houses or apartments, the panel may already be busy. That does not rule out Level 2, but it may shape the choice: • Lower-power Level 2 can fit where a high-power unit would overload the system • Smart charging can cap current or react to other loads • A future panel upgrade can be planned when more EVs or electric appliances arrive   On the cost side, Level 1 mostly uses what is there. Level 2 adds the cost of hardware and installation, which can be modest if the panel and parking spot are close or higher if cable runs are long and walls are finished. Over time, being able to rely on home Level 2 and off-peak tariffs can also reduce how often you need to pay for public charging.   When Level 1 is genuinely enough Level 1 has a place. It can be a long-term solution when several conditions are true: • Average daily distance is low, for example under 20–30 km • The EV is a second car for local errands and short commutes • The car can stay parked overnight for 10–12 hours most days • There is little need to recover a very deep discharge in a single night   In that case, Level 1 simply becomes a quiet habit: plug in most nights, and the car is ready every morning without much thought. A practical way to test this is to start with Level 1 and watch for a month or two: • How often do you wake up with less range than you would like? • How often do you feel forced to find a public charger just to catch up?   If the answer is “almost never”, then Level 1 may already be all you need.   When Level 2 makes life noticeably easier Level 2 deserves serious attention when: • Daily or weekly mileage is high • One EV is the main car for most trips in the household • Work, school or family schedules leave shorter charging windows • You want more flexibility for last-minute plans or weekend getaways   In these situations, Level 2 changes the rhythm. You can come home late, plug in for a few hours, and still have a comfortable buffer by morning. You are less dependent on finding a free public charger at the right time.     A simple checklist to decide If you answer “yes” to three or more, Level 2 is very likely worth the investment: • My typical weekday round trip is above about 50 km • I often drive several separate trips on the same day • I cannot always leave the car plugged in for 10–12 hours at home • I plan to keep this EV for several years and expect mileage to stay high • I may add a second EV to the household within the next two or three years   If most answers are “no” and your driving is light and predictable, a well-installed Level 1 solution can remain a sensible and economical choice.   If you also look after company cars or pool vehicles, you can use our guide on what level of EV charging fleets really need to plan depot and workplace charging.     Home charging solutions from Workersbee Different homes and driving patterns call for different hardware. Some drivers benefit from flexible, portable equipment that can follow them between outlets. Others need a fixed unit that becomes part of the driveway or garage.   Workersbee supports both approaches with portable EV chargers for home use. Installers can match these options to local grid conditions, plug standards and panel capacity so that home charging remains safe, reliable and convenient over the long term.   If you are curious how the hardware changes when you move from home AC charging to high-power DC fast charging, our AC vs DC EV charging hardware guide explains what happens inside the connector and cable.     FAQs: common home charging questions Is Level 1 charging bad for my EV battery?Level 1 uses low power and is generally gentle on the battery. The battery management system controls charging in the same way as with Level 2, as long as temperature and state of charge stay within normal ranges.   Can I use an extension cord for Level 1 home charging?Most extension cords are not designed for continuous high load. They can overheat, especially when coiled. For regular home charging it is safer to use a dedicated outlet or charging point installed by an electrician.   Do I still need Level 2 if I can charge at work?Reliable workplace charging reduces the pressure on home charging, but life does not always follow office hours. A home Level 2 charger gives flexibility for early starts, late returns and days when workplace chargers are busy or out of service.   Is it okay to start with Level 1 and upgrade later?Yes. Many owners start with Level 1 to understand their driving pattern and the local charging network. When they feel that charging is holding them back, they upgrade to Level 2 with a clearer view of what they actually need.
