Electric Car's Charging Speed

We all cherish the idea of swift EV charger installations, making shifting to an electric vehicle (EV) lifestyle more effortless. However, have you ever pulled up to a charger to realise your car isn’t charging as fast as promised? Let’s discuss why.

The Confusion Behind Charging Times

Electric vehicles (EVs) are paving the way for a more sustainable and environmentally friendly future. However, one of the most significant concerns, especially for new and prospective EV owners, revolves around charging times. Despite the rapid advancements in EV technology, understanding why charging takes a certain amount of time and may not always match expectations can be perplexing. Let’s look into the underlying factors and challenges contributing to this confusion.

A Web of Terminologies

First and foremost, the EV industry is riddled with technical jargon that can easily overwhelm someone new to the space. Terms like kilowatt (kW), kilowatt-hour (kWh), AC (Alternating Current), DC (Direct Current), and fast charging are just a few of the terms EV owners must familiarise themselves with. Often, confusion arises when differentiating between kW and kWh, with the former denoting charging power and the latter representing battery capacity.

1 – Misleading Advertisements

Sometimes, charging station manufacturers or EV brands might advertise “up to” certain speeds. For instance, a charging station may promote “up to 150 kW” charging, but that doesn’t mean every EV can utilise that full power. Hence, even if a station claims to be ultra-fast, the actual charging speed an EV user experiences can be quite different.

2 – Complex Mix of Variables

Unlike traditional vehicles, where refuelling is relatively straightforward, EV charging depends on many factors. These can range from the vehicle’s battery size and health, the charging station’s capabilities, the state of charge, weather conditions, and even the car’s age. The sheer number of variables in play can make it hard to predict exact charging times consistently.

3 – Real-world vs. Theoretical Charging Speeds

Manufacturers often provide theoretical maximum charging speeds. However, in the real world, factors such as simultaneous charging (where multiple vehicles share the same charger or power source), battery temperature, and even sitting in the car using other features can all contribute to extended charging times.

4 – State of Charge (SoC) Anomalies

For many new EV owners, the concept that charging from 20% to 40% might be faster than 80% to 100% can be confusing. This tapering of charging speed at higher SoCs can lead to unpredictable wait times, especially for those using the consistent refuelling time of fossil fuel-powered vehicles.

5 – Infrastructure Inconsistencies

While some cities have the latest fast-charging infrastructure, others may have outdated or less efficient chargers. Hence, an EV owner’s experience in one town might be entirely different in another, leading to inconsistent perceptions of charging times.

Electric Car Charging Speed Simplified

Understanding how long it’ll take to charge your electric vehicle (EV) is vital for planning trips and daily commutes. With a straightforward formula, you can determine the approximate charging time of your EV:

Battery size (kWh) ÷ Charger power (kW) = Charging time (hours)

Let’s break this down with a few examples:

  1. Renault Zoe: With a battery capacity of 52kWh, when attached to a 50kW rapid charger, it takes just over an hour to fully charge the Zoe.
  2. Kia e-Niro: With a larger 64kWh battery, the Kia e-Niro will take around one and a half hours when using the same 50kW charger.
  3. Tesla Model 3 Long Range: This model has a 70kWh battery, giving an approximate charging time of one hour and forty minutes with a 50kW charger. However, Tesla’s Supercharger network offers super fast charging speeds, providing up to 172 miles of range in a mere 15 minutes.

Remember, the actual charging time can vary based on the battery’s state, charger efficiency, and other environmental factors. For a more accurate and EV-specific charging time, consider using a dedicated EV charger installation at home, consulting with a Zappi installer, or looking into home electric vehicle charger installation options. An EV home charger lets you conveniently charge car at home, ensuring a full battery whenever you’re ready to hit the road.

Factors Influencing Your EV Charging Time

As electric vehicles (EVs) lead us to a greener tomorrow, new and potential EV enthusiasts often grapple with understanding charging durations. Even with the leaps in EV technology, grasping why it takes varying lengths of time to charge, sometimes contrary to expectations, can be a puzzle. Let’s look into unravelling the factors adding to this puzzle.

1 – Battery Capacity

2 – Charging Power (kW) and Charger Type

3 – State of Charge (SoC)

4 – Battery Health and Age

5 – Temperature and Weather Conditions

6 – Vehicle and Charger Compatibility

Questions Looming on Your EV Journey

Are you considering an EV home charger to charge your car at home? Are you mulling over whether to engage a Zappi installer? There are numerous considerations on this green journey. Questions about home charging, cables, and on-the-go charging solutions may arise besides charging times. Always turn to a professional EV charger installer for these and more, ensuring your electric mobility transition is as smooth as possible.


Transitioning to an EV-rich future involves more than just the mechanics of EV charger installation. The efficiency of your charge, the longevity of your battery, and the nuances of electric vehicle charger installation are all intertwined in this green journey.

By understanding the factors influencing your charging times, you can better navigate and enhance your EV experience. Ready to power up and drive into a cleaner tomorrow?

Cut Your Electricity Costs by 75%

A battery storage system can slash your electricity bill by up to 75%. Storing extra energy during off-peak periods and using it during high-demand times helps minimize reliance on the grid, especially when electricity rates are typically higher. This straightforward solution not only saves you money but also contributes to a more sustainable and efficient energy consumption pattern.
