Selecting the ideal EV charging station depends on several factors specific to your project. We’re happy to guide you through this process to ensure you get the best fit.

Here’s a breakdown of some key considerations:

  • Application Type: Residential: For home charging, Level 2 AC chargers, also known as wallbox chargers, are typically sufficient. These offer charging speeds between 16-32 amps, ideal for overnight or long-term charging.
  • Application Type: Commercial & Industrial: For businesses and industrial settings, DC fast chargers provide significantly faster charging. These stations can deliver maximum currents of up to 400 amps, enabling charging speeds of up to 350kW. However, most commercial DC fast chargers typically offer speeds in the range of 50-150kW, catering to a wider variety of electric vehicle models and usage needs.

 

In addition to these factors, we recommend considering:

  • Power Requirements: Evaluate the typical battery capacity and charging needs of the electric vehicles you expect to serve.
  • Number of Charging Stations: Determine the optimal number of stations required to meet your expected usage volume.
  • Site Considerations: Assess the available space and electrical infrastructure at the installation location.

 

By working collaboratively with you and understanding your specific project requirements, we can recommend the most suitable charging station model and configuration.

Absolutely! Our EV charging stations are designed to be versatile and adaptable for a variety of locations, including:

  • Residential Homes: We offer Level 2 AC charging solutions ideal for convenient and safe overnight charging in your garage or driveway.
  • Commercial Businesses: Our portfolio includes a range of charging options suitable for workplaces, shopping centers, and other commercial settings, catering to employee and customer needs.
  • Public Locations: We can provide comprehensive charging solutions for public parking lots, highway rest stops, and other public spaces, promoting wider EV adoption.

 

To ensure you receive the most suitable charging solution for your specific needs, our experienced team will conduct a thorough evaluation of your project. This allows us to recommend the optimal station type, power capacity, and number of charging units required.

We offer a range of charging station options to cater to diverse power level needs:

  • Level 2 AC Charging: These stations are well-suited for residential and commercial applications, typically utilizing a 240-volt power source similar to household appliances like dryers. Level 2 chargers deliver power up to 19.2 kW, enabling charging speeds of around 40 miles per hour, ideal for overnight or long-term charging.
  • Level 3 DC Fast Charging: For locations requiring significantly faster charging capabilities, we offer Level 3 DC fast charging stations. These stations operate on high-voltage power (480 or 1000 volts) and can deliver maximum power outputs of up to 400 kW. This translates to charging times as fast as 30 minutes for a full charge, perfect for public settings or situations where rapid charging is essential.

 

Understanding Charger Compatibility:

It’s important to note that each electric vehicle has a built-in onboard charger with a specific power handling capacity. This onboard charger communicates with the charging station to ensure it receives the optimal amount of power for safe and efficient charging. In simpler terms, there’s no risk of “overcharging” an EV – the onboard system regulates the process.

Choosing the Right Power Level:

Our team of experts can assist you in selecting the most suitable charging station type (Level 2 or Level 3) based on your specific project requirements, including factors like:

  • Typical Charging Needs: Consider the average charging time desired for your application.
  • Site Electrical Infrastructure: The available power supply at the installation location will influence the compatible charging station type.
  • Intended Use Case: Evaluate whether overnight charging or rapid charging capabilities are more important for your project.

 

By working collaboratively with you, we can ensure you get the charging solution that perfectly aligns with your power level requirements and project goals.

Yes, our charging stations are designed to be future-proof and compatible with evolving smart grid technologies. This includes the potential for bi-directional charging capabilities.

Understanding Bi-Directional Charging:

Bi-directional charging is an innovative technology that allows electric vehicles (EVs) to not only receive power from the grid but also feed excess power back into it. This two-way flow of energy offers several potential benefits:

  • Grid Strain Reduction: By strategically charging EVs during off-peak hours and discharging power back to the grid during peak demand periods, bi-directional charging can help alleviate strain on the electrical infrastructure.
  • Cost Savings: EV owners can potentially benefit from lower electricity rates by charging their vehicles during off-peak hours when energy prices are typically lower.
  • Enhanced Grid Stability: The ability to add or remove power from the grid through bi-directional charging can contribute to a more balanced and efficient energy ecosystem.

 

Compatibility Considerations:

It’s important to remember that bi-directional charging requires compatibility on two fronts:

  • Charging Station: The station itself must be equipped with the hardware and software necessary to facilitate bi-directional power flow.
  • Electric Vehicle: The EV needs to have the capability to both receive and deliver power through its onboard charging system.

 

Future-Proofing Your Investment:

The landscape of EV technology is constantly evolving, and bi-directional charging is a promising development for a more sustainable energy future. By choosing charging stations designed with this potential in mind, you’re making a future-proof investment in your EV charging infrastructure.

Our Expertise:

Our team of specialists can help you navigate the compatibility aspects of bi-directional charging and determine if it aligns with your project goals. We can recommend charging station models that support this functionality, ensuring you have the right technology in place to embrace future advancements in smart grid integration
