  1. User payment options.
  2. Commercial maturity (charger management).
  3. Standard warranty length.
  4. Power rating (in kW) available per plug.
  5. Dual plug with high power capability option.

  • Number of Charging Ports/Type (e.g. Type 1 and Type 2).
  • Input Power: The power circuit required to support the charger.
  • Output Power: Maximum power deliverable to an electric vehicle.
  • Mounting: Either pedestal or wall.
  • Cross-Vendor Software Compatibility: Can this charger use other manufacturers’ software?

Management Software

  • Network capable: Can the charger utilize network management software?
  • Remote management: Can charger information and settings be accessed remotely?
  • Network protocol: Protocol for communication between EV chargers and network.
  • Demand Response Capability: Ability to adjust the power output in response to grid demand.
  • Data reporting: Available data generated by charger.

Stand-Alone vs. Networked Chargers

Stand-alone or "dumb" electric vehicle (EV) chargers have no network access and are essentially just basic outlets with built-in circuitry for safe charging and communication with the vehicle.

Without network access, stand-alone chargers cannot process payment and are generally reserved for residential or fleet applications.

While these chargers lack the advanced features of networked charging stations, they can still provide a reliable and convenient charging option for EV owners.

Stand-alone chargers have lower installation costs, simpler designs, and no recurring fees for features such as payment processing and cloud connectivity. They may also be the only viable option in locations with limited cellular coverage, or for low-traffic sites where network charges surpass the cost of providing free access.

Networked Chargers add a variety of capabilities. For drivers, services may include payment options, real-time station location, and availability information, and options such as reservations, messaging, and summary reports. Site host services include payment management, customer support, station status, data reporting, and typically access to a network “dashboard”.

A service network provides supervision and support for one or more EV chargers. These services are available to both EV drivers and network administrators or site hosts, with varying fee structures targeted at each group.

One additional thing to consider with regard to networked chargers is whether or not they are compliant with Open Charge Point Protocol (OCPP). OCPP-compliant hardware and software are designed to function together regardless of manufacturer. Typically, this allows charging site hosts to mix and match charging stations while choosing the network provider of their choice.

The good news is that Grasen's AC chargers support connection with third-party CSMS, and we also offer customized charging software & management platform too.

Payment System

  • Open Access: Can any customer charge or is a service subscription required?
  • Customer payment: Possible customer payment methods.
  • Price Setting Option: Potential fee structures the owner can set.

Manufacturer/Certification Information

  • Listings: Product testing certifications (e.g. UL, CE, etc.)
