How To Estimate Your EV’s Charging Time

When contemplating the switch to an EV from a gas powered car, charging time is one of the first considerations everyone looks into. The process of fueling up an EV can feel like an unknown when a driver has spent years filling up an ICE (internal combustion engine) vehicle. While pumping gas takes a few minutes, how long does it take to charge an EV?

How Long Does It Take To Charge An Electric Vehicle?

An EV’s charging time depends on two major factors: how much charge (kWh) is needed, and how much power (kW) the EV charging station provides. Divide the charge needed by the power provided to get the estimated hours of charge time required. There are other variables that play into this calculation but these two factors are the most significant variables when estimating your electric vehicle’s charging time.

Calculation for EV Charging Time:

To calculate your charging time, divide the amount of charge needed by the power provided by the charger. Use the formula and example below to help estimate your charge time.

Charge needed (kWh) / Charger power (kW) = Hours of charging time

A Tesla Model 3 with an 80 kWh battery size parks at a 7.68kW Level 2 charging station with 20% battery left. They would like to charge their EV to 80%.

Find charge needed:
80% – 20% = 60% needed
80kWh x 0.6 = 48kWh needed

Calculate charging time:
48 (kWh needed) / 7.68 (kW charging speed) = ~6.25 hours of charging time

How Much Charge Does My EV Need?

To estimate how much charge your EV needs, subtract the EV’s max battery capacity (kWh) from the amount of charge it has left. Most, if not all, EVs will display the remaining battery percentage or number of kWh left within the battery. Just as most people do not wait until their gas cars are completely empty, EV drivers will always have some charge left in the batteries when they stop to refuel.

According to an EV Consumer Behavior report, about 70%-80% of EV drivers charge at home or at work every day/night or every other day/night. The average American drives around 250 miles per week or roughly 36 miles per day. This equates to around 10-13 kWh of charge per day or 20-26 kWh every other day. The average EV battery size is around 40-50 kWh, providing around 150 miles of range or 2-4 miles per kWh. Knowing your EV’s battery size and efficiency will help shape your charging routine when estimating your EV’s range. Tips on how to improve your EV’s range.

How Fast Is The EV Charger?

Charging speed is determined by the amount of kilowatts (kW) a charging station can provide per hour (kWh). There are 3 types of EV charging stations, all with varying levels of charging speeds: Level 1, Level 2, and Level 3 (DC fast charger). As the names suggest, the higher the level, the faster the charging speed. Most chargers will display their charging speed either on the charger itself or within a connected charging app.

Level 1: 12A/120V

  • Kilowatts per hour: 1.44 kWh
  • Range per hour: ~4mi

Level 2: 32A/240V

  • Kilowatts per hour: 7.68 kWh
  • Range per hour: ~24mi

Level 3 DC Fast Charger: 100A/480V+

  • Kilowatts per hour: 50kWh+
  • Range per hour: 150mi+

The majority of EV charging happens on Level 2 and Level 3 charging stations as Level 1 chargers are generally too slow for most drivers. While Level 3 is faster, Level 2 chargers tend to be more practical for installation and supporting most drivers’ daily needs. Check out the difference and which charger or configuration of chargers is best for your property.

Other Factors To Consider When Charging an EV

Other factors such as load sharing, temperature / weather conditions, EV battery protection settings, and EV charge acceptance rate can play a role in an EV’s charging time. While these factors are unique to the car model and charging location, they are important for EV drivers to know and take into consideration when starting a charge or planning their route for the day.

EV Charger Load Sharing:

EV charger load sharing is when two or more EV charging stations are connected to the same circuit and power / load is distributed between all the stations connected. In most cases, the power is only split if multiple EVs are charging at the same time on the same circuit. So if four chargers were installed on one circuit, you would receive 100% of the power if charging by yourself, and 25% of the power if every charger was being used. While this can potentially increase a driver’s charge time, load sharing is a great strategy for properties looking to manage their electrical load and/or add a larger number of chargers to their property.

Weather and Temperature Effects On Charging:

Weather and temperature conditions can play a role in the efficiency of your charge. Charging stations and EVs will often charge slower in extreme temperatures to preserve the health of the batteries. Many EV drivers will also stay inside their cars while charging at public charging locations. Running the climate control while charging can increase charging times, especially on very hot or cold days. Allocate some extra charging time or find charging stations in more protected environments when charging in these conditions. Extreme temperatures can have an even larger effect on an EV’s range.

EV Battery Protection Settings:

Many EV manufacturers will have default or recommended battery restrictions, driving modes, and other settings to protect the short term and long term life of the battery. For instance, some manufacturers recommend charging their batteries to 80% max and avoid going under 5%. While following these kinds of guidelines may decrease the range of one charge, they are meant to preserve the lifespan of the batteries with an added benefit of saving some charging time by not having to go all the way to 100%. Of course most of these are just recommended settings and can be changed at the owner’s discretion.

EV Charge Acceptance Rate:

The EV charge acceptance rate is the maximum kW an EV is able to consume or accept from a charging station. Many EV manufacturers will throttle or cap the rate of power their EVs can consume . The acceptance rate for an EV can decrease as it gets closer to 100% charged. For example an EV could be charging at a 100 kWh Level 3 fast charger and receive 100 kWh from 10-80% but slow down to 65kWh from 80-100%. This information will be noted in the manufacturer’s specifications of the vehicle.

What is the Difference Between a Smart EV Charger and Dumb EV Charger?

The difference between a smart EV charger and dumb EV charger is its level of functionality and control. While dumb chargers are only capable of providing electrical charge to an EV, nothing more, a smart charger has the ability to provide additional functionality such as energy load management, restricted access, remote start / stop, status / session monitoring and much more.

For property owners installing several chargers, understanding the difference is crucial.

What is a dumb EV charger?

A dumb EV charger is an electric vehicle charging station that provides an electrical charge to an electric vehicle when plugged into the vehicle and connected to a power source. Like most electronic device chargers, its only function is charging an EV while plugged in – no monitoring, no controls, just charge.

It is also important to note that dumb chargers are not networked. This means the charger hardware is not connected to or in communication with a larger network. Because of this lack of communication, the charger is not capable of being monitored or tracked. While dumb chargers do not contain the hardware or software required to be connected to a network, smart chargers can be installed as non-networked chargers if desired.

What is a smart EV charger?

A smart charger is an electric vehicle charging station that has the ability to monitor, control, and report on its charging functionality to an operator via a centralized or cloud based network. Smart chargers contain hardware and software that can control its functions such as the ability to load manage available power, restrict charger access, report charger availability, relay charging session information, alert to hardware abnormalities, support and troubleshoot issues remotely, and much more.

Smart chargers are often referred to as networked chargers because they are usually installed and connected to a larger integrated network via Wi-Fi, SIM, or hardwired to an internet source. The network connection is what provides EV drivers and property owners the ability to control and monitor the charger’s functions from anywhere. While dumb chargers can never be smart / networked chargers, smart chargers can be installed as a dumb / non-networked charger if desired. This can provide the owner the ability to connect it to a network in the future and turn on networked charger functionalities.

Is a smart EV charger better than a dumb EV charger?

In most cases, yes, smart chargers come with more capabilities and controls which benefit EV drivers, homeowners, and commercial / multifamily property owners. The primary benefit of getting a dumb charger over a smart charger is they are typically cheaper to buy and install. While fewer capabilities translates to a lower price tag, for most, the benefits from the added software and functionality in a smart charger greatly outweigh the difference in price.

Also note that some EV charger rebate and incentive programs require properties to install smart, networked chargers in order to receive project funding.

How to choose the right smart EV charger

Finding the right smart charger for your property boils down to how much control and functionality is desired. While a single family homeowner might just be interested in seeing analytics on their charging sessions or be alerted when their car is finished charging, owners of commercial and multifamily properties often need much more. Commercial and multifamily property owners might want to charge EV drivers for their electrical usage, restrict access for private parking spaces, set up a charging valet service, load balance their power consumption, and more. Choosing the right smart charger means choosing the right network provider for your needs.

Level 2 vs. Level 3 EV Charging Stations: What’s the Difference?

As the electric vehicle (EV) ecosystem has evolved to meet the various needs of drivers and their lifestyles, different kinds of EV charging stations have emerged, including Level 2 and Level 3 options. As multifamily and commercial properties explore which option aligns best with their buildings, residents and tenants, there are several key factors to consider.

Power requirements

Level 2 chargers require a 240-volt electrical source, much like an oven range or clothes dryer. Level 3 chargers require a 480-volt electrical source, which is also used to power industrial motors and heating applications. For comparison, a standard wall outlet delivers 120 volts. When selecting chargers, it’s crucial to consider the power available to the property so owners and managers can deliver solutions that are not only reliable and effective, but safe.

Level 2 Charging Station

Physical specifications

When it comes to size, a Level 2 charger is much smaller than a Level 3 charger, which can clock in at upwards of 500 pounds. Each charger is also equipped with varying plug types – a Level 2 utilizes a J1772 plug while a Level 3 uses CCS and CHAdeMo plugs.

Level 3 Charging Station

Installation cost

It’s no surprise that there is a significant cost difference between EV chargers, with a Level 3 charger potentially costing upwards of 200 times more than a Level 2 charger. A property’s overall installation cost will vary by project and depend on factors like charger specs, labor, physical placement, mounting requirements and any potential electrical upgrades that may be required. Local rebate and incentive programs often cover both charger types, though details will vary by provider.

Charging time

Drivers using a Level 2 EV charging station can typically expect to return to a fully charged car after a couple hours. A Level 3 charging station, also called Direct Current Fast Charging (DCFC), can deliver a full charge in approximately 30 minutes. These timeframes are estimates and will vary based on the car and battery type.

Use case

Level 2 charging stations are most commonly found in locations of longer dwell times, like multifamily communities and office buildings. These locations enable drivers to conveniently charge their EVs while doing something else for a couple hours, like relaxing at home or working during the day. Level 3 charging stations are often found along busy transportation corridors and used by drivers who are on the go and looking to get back on the road as quickly as possible. Level 3 chargers can also be a great solution for fleet and other enterprise needs.

Partnering with Chargie
