Planning your EV charging strategy starts with a simple question: how much charging do your residents or guests actually need?


For most multi-unit residential buildings (MURBs), the challenge isn’t just selecting chargers - it’s balancing driver behaviour, costs and your building’s electrical capacity. 


Should you prioritize a few fast chargers, or spread low-power chargers across more stalls?


The answer depends on how your building’s residents and guests use their vehicles.


Most EV drivers in the U.S. travel 25–35 miles (40-56km) per day,  typically recharging when they’re at a low at 20-30%~, and topping back up to a healthy  80% to preserve battery health.


In this guide, we break down real-world scenarios across Level 1, Level 2, and DC fast charging, using three of the most common EVs in North America to show how much charge and how quickly each Plugzio solution delivers per charging session.


Before we dive in, let’s revisit a few key concepts:

  1. kW vs.kWH 

  2. How to translate daily mileage into charging needs

  3. Charging speeds across Plugzio devices

  4. What impacts charging time and efficiency



  1. kW vs. kWh 

It helps to understand two key terms - kWh (kilowatt-hour) and kW (kilowatt)


  • kWh is a unit of energy, telling you how much electricity your battery can store or use for 1 hour.

    • Example: a 60 kWh battery can store 60 units of energy.


  • kW is a unit of power, telling you how fast energy is delivered to the battery.

    • Example: a 10 kW charger delivers 10 kWh of energy in 1  hour.


Power (kW)  = Voltage x Current


💡Plugzio Tip:  Think of kWh as the size of a fuel tank, and kW as how fast the fuel flows in.


  1. How to translate daily mileage into charging needs

Simple rule of thumb:

  • 1 kWh ≈ ~3 miles (5 km) of range

This lets you quickly estimate how much range a charger delivers:

  • Miles added per hour = Charger power (kW) × 3



  1. Charging speeds across Plugzio devices


Let’s walk through a common scenario:

  • EV battery size: 60 kWh

  • Current charge: 20% (12 kWh)

  • Target charge: 80% (48 kWh)

  • Energy needed: 36 kWh


Using Plugzio U+  (240V, 16A – 3.84 kW)

  • Charging time: 36 kWh ÷ 3.84 kW ≈ 9.4 hours

  • Driving range added: 36 kWh × 3 ≈ 108 miles


Using Plugzio Artemis (240V, 48A – 11.52 kW)

  • Charging time:36 kWh ÷ 11.52 kW ≈ 3.1 hours

  • Driving range added: 108 miles 


The difference isn’t how far you can go - it’s the same range added  in just a third of the time.

  1. What impacts EV charging time and efficiency


  • Vehicle efficiency: Not all EVs are made equal, some EVs get 4-5 miles per kwh, others on the lower end closer to 2.5

  • Battery behaviour: Charging slows as the battery approaches full, especially above 80%

  • Weather: Cold temperatures reduce charging efficiency.

  • Driving Conditions: High speeds and heavy loads consume more energy.

  • Load Balancing: If multiple vehicles are charging on the same circuit, available power may be shared.



Real-World Charging: What EVs Actually Get with Plugzio?


To see what this all looks like practice -  let’s look at three of the most common EVs on the road today: Chevrolet Bolt, Hyundai IONIQ 5, and Volkswagen ID.4 specifically the speed of charging, and range added across Plugzio’s broad portfolio of EV chargers: 


We’ll compare charging speed and range added per session under consistent conditions:


  • Current charge: 20% 

  • Target charge: 80% 

  • Energy conversion: ~1 kWh ≈ 3 miles of range


Car Model & Charging Condition(s)

Universal + L1

Artemis L2 - 11.5kW

Artemis L2 - 19.2kW

Ampax L3 - 240kW

Chevrolet Bolt


  • EV battery size: 65 kWh~

  • Current charge: 20%  (13kWh)

  • Target charge: 80% (52kWh)

  • Charging Time: 39kWh ÷ 3.84kW ≈10.1 hours

  • Driving Range Added: 39kWh x 3 ≈ 117 miles




  • Charging Time: 39kWh ÷ 11.5kW ≈3.3 hours

  • Driving Range Added: 39kWh x 3 ≈ 117 miles


  • Charging Time: 39kWh ÷ 19.2kW ≈2.0 hours


  • Driving Range Added: 39kWh x 3 ≈ 117 miles

🧠 Key Takeaways


  • 1 kWh = ~3 miles (5 km) of range

    • To calculate range delivered: Miles added per hour = Charger power (kW) × 3

  • Level 1 (Universal+) works well for overnight or long-dwell charging (8+ hrs)

  • Level 2 (Artemis) hits the sweet spot for daily use and turnover (2-3 hrs), and shaves down charge time by 67% versus Level 1!

  • DC Fast Charging (Ampax) delivers rapid top-ups in minutes, ideal for high-traffic or commercial settings (<15 minutes)
