Tesla accounted for 1.36 million Electric Vehicles sales in 2022 and 440,000 units EVs in Q1 2023.


Several states plan to ban sales of gas-powered cars after 2035. Only zero-emission vehicles can be sold.

All electric cars are expected to reach 17.07M units in 2028. New EV sales would make up 75% of total sales by 2030.

EV Basics

YES, electric cars can be worth it for many reasons: cost saving, superior driving performance, zero tailpipe emissions and a smaller carbon footprint. And the opportunity to engage with cutting-edge technologies such as Autonomous Driving. Augmented Reality (AR) Interfaces, Vehicle-to-Grid Integration.

Typically, electric car batteries last 8-15 years or 100,000-200,000 miles before significant degradation.

Even after an EV battery reaches the end of its lifespan, it doesn’t necessarily mean you can’t use the EV anymore. Just can not hold its full capacity, but can still provide enough range for certain driving needs, especially for shorter commutes or local trips.

Additionally, some EV owners choose to replace the battery to restore the vehicle’s range and continue using it. Advancements in battery technology are improving longevity, and manufacturers often provide warranties for a specified duration.

While the number of electric vehicles (EVs- currently at 16.5 million) on the road may seem small compared to the total global car count of 1.4 billion, it signifies an impressive 300% growth in EV sales since 2018. With 1.7 million electric cars currently in operation in the USA.

The momentum continues to build, with electric car sales doubling between 2020 and 2021, reaching an impressive 6.6 million sales.

The range of electric cars, both battery electric (BEV) and plug-in hybrid electric (PHEV), can vary based on factors like the vehicle model, battery capacity, driving conditions, and individual driving habits.

On average, a fully charged BEV can travel around 100 to 300 miles (160 to 480 kilometers) before needing a recharge, while PHEVs usually have a shorter electric-only range of about 20 to 80 miles (32 to 128 kilometers).

Charging an electric vehicle can be convenient as it can be done at home or work while the car is parked for an extended period throughout the day or night. In general, EV charging can take anywhere from 30 minutes to 4-20 hours.

Fast charging options like DC, where drivers can now typically charge in 15-45 minutes. While slower charging options, like Level 2 EV chargers, may take 4-8 hours and Level 1 for overnight.

For example, public charging rates for electric vehicles are approximately 20 cents per kilowatt-hour (kWh) for Level 2 charging and 30 cents per kWh for DC fast charging (DCFC). To provide an example, let’s consider a Nissan LEAF with a 150-mile range and a 40-kWh battery. The cost breakdown for a full charge would be approximately $8 for Level 2 charging and $11 for DCFC.

Accordingly, cost per mile for electric car is significantly more cost-effective than gas car fueling, with an average cost of $0.05-0.08 per mile for EV charging compared to $0.12 per mile for a compact sedan running on gasoline.

The easiest and best place to charge your electric vehicle is at home, with studies indicating that 80% of charging occurs at home. However, EV owners can also easily find public charging stations across the US using various maps or smartphone apps, shows locations and availability such as service stations, car parks, supermarkets, cinemas, and roadside spots.

Starting from January 1, 2023, US state buildings exceeding $100,000 project costs must install Level 2 EV charging stations at a minimum of 20% of LDV parking spaces. In Europe, new commercial or multi-unit dwelling buildings with at least 30 LDV parking spaces must support Level 2 or DCFC stations at 10% of such spaces. Additionally, new residential buildings with over ten parking spaces need pre-wiring for charging points in each space, while commercial buildings require 20% of spaces to be pre-wired.


Average commercial EV charging station cost of a basic Level 2 charging station (240Volt) can range from $200 to $700, if we only consider equipment cost. While a DC fast charging station (480V) can range from $12,000 to $30,000 or more.

It’s important to note that infrastructure, installation costs, and ongoing maintenance should also be considered.

To charge your EV at home, you’ll need either a 120V Level 1 charger or a Level 2 charger operating at 240V. The cost of these chargers varies.

On average, a Level 1 chargers range from $150 to $500, while Level 2 charger hardware costs range from $200 to $700. If you already has a 240V outlet in garage, installation costs can range from $250 to $700. For those without a suitable outlet, installation packages can cost anywhere from $400 to $1,600.

Level 2 EV charger is the fastest means of home charging, which is why 80% of EV drivers choose to charge their EV at home. While DC fast charging is faster, it is typically only available at public charging stations.

A Level 2 charging operates at 208-240 volts and outputs anywhere from 3.7 kW to 12 kW of AC power due to different amp ratings of 16, 32, 40, or 50 amps. Level 2 home charger can be plugged into a three-pronged NEMA 14-50 outlet, which is typically used for electric ovens or clothes dryers.

Level 2 charging station provides 25 miles/hour charging speed, full charge takes about 5-8 hours instead of 20+ hours of Level 1.

CCS (Combined Charging System) is a DC fast charging standard for electric vehicles (EVs). It combines both AC and DC charging port in a single connector. CCS chargers are designed to provide high-power DC fast charging, allowing EVs to charge rapidly up to 350kW (500A Max) and extend their driving range to 80% in just 15-45 minutes.

CCS adapter,  is a necessary device that allows EVs to charge from different charging connectors at CCS charging stations. It ensures compatibility and flexibility, enabling EVs without a built-in CCS connector to access the fast charging capabilities provided by CCS chargers.

SAE J1772 charger is a standard connector widely used in U.S. & Japan for EV Level 1 and Level 2 charger of EVs. It provides single-phase AC power at varying voltages and currents, typically up to 240V and 80A. And, it is compatible with most EVs available in the market.

A J1772 adapter is a EV charging device that allows different charging connectors to a J1772 charger. It provides compatibility and enables EVs with non-J1772 connectors to access J1772 charging stations.

It is beneficial for all EV drivers having a J1772 adapter to access wider range of charging infrastructure, especially in regions where J1772 chargers are prevalent.

EV Charger adapter works as a converter between the charging plugs of the station and the charging port of the EV. It is necessary for EV drivers who frequently on the road and rely on public charging stations.

EV charging adapters will greatly enhance your charging options and allow to charge an EV at broader charging stations, expanding your charging network and providing superior convenience.

The cheapest and slowest home charging option is using a 120V Level 1 charger, which takes approximately 10 hours or overnight to fully charge the EV. It plugs into a standard home outlet and utilizes home electricity.

For faster home charging, EV owners can opt for a Level 2 charger, also known as a home wall connector or wall charger. Home EV charger level 2 is typically installed in garages and can provide a charging rate of about 25 miles per hour. 240V Level 2 chargers are the most popular choice for home charging, excluding public charging stations. and you need to contact a licensed electrician to get an estimate and to determine if a permit is required.

Level 1, Level 2, and DC fast charging are different types of charging options available for electric vehicles (EVs), each offering varying charging speeds.

Level 1 charging refers to standard household outlet with a 120-volt AC charging. The slowest but easiest charging option and typically provides a charging speed of 4-5 miles of range per hour. Level 1 chargers are commonly used for overnight charging at home or in certain condition when faster charging is not required.

Level 2 charging utilizes a 240-volt AC supply and provides a faster charging rate compared to Level 1. It can deliver around 10-30 miles of range per hour, depending on the charger’s power output. Drivers with longer commutes or who want a faster charge or a longer electric driving range should consider choosing a Level 2 charging station.

DC fast charging, also known as Level 3 charging, allows EVs to charge rapidly. DC fast chargers can provide 60-80% of battery capacity in approximately 20-30 minutes, making them the fastest charging option available. They are ideal for long-distance travel and quick recharging and are commonly found at public charging stations only.

DC fast charging is generally considered safe for EV batteries, but frequent and prolonged use of DC fast charging can degrade the battery faster than AC charging over time.

It is recommended to use DC fast charging when necessary, such as during long trips, but for everyday charging, it is preferable to use slower charging methods like Level 1 or Level 2 charging to promote battery longevity.
