DC charging solutions for small public sites and fleet depots where AC charging is no longer sufficient.
20–30kW DC fast charging delivers power directly to the vehicle battery without using its onboard AC charge. This power range is used when AC charging no longer meets turnaround needs, while higher DC power would add unnecessary complexity.
This DC charging system is applied in targeted charging scenarios where DC power is required without moving into full commercial DC deployment.
Provides DC charging power suited for short sessions, pilot sites, and low-volume daily use.
Designed to support one charging session at a time for predictable, low-traffic operation.
Provides DC-side energy data for basic usage records and operational checks.
Connects to backend systems for monitoring and basic operational visibility.
Designed for sites where DC charging is introduced without reworking entire electrical layout.
Applied where DC charging apply a specific operational gap rather than scaling site capacity.
These specifications outline the main technical parameters of a 20-30kW DC fast charging system and help ensure compatibility with common electric vehicles (EVs) and commercial installations.

Entry-level DC charging is used when AC charging no longer fits daily operations, but higher DC power cannot be justified under traffic or site conditions. It is ideal for projects that need faster turnaround without investing in extensive DC infrastructure.
Vehicles stay for 30–60 minutes, and AC chargers cannot deliver a meaningful recharge within that time.
Charging site traffic is limited, and 60kW or higher DC power would remain underutilized for most of the day.
Small sites, fleet depots, and commercial locations that need basic vehicle turnover without heavy grid.
AC charging no longer meets daily turnaround needs, but site power does not justify standard DC deployment.
20–30kW DC is used as an entry point, where limited traffic and controlled usage define the operating model.
Used when three-phase AC still completes charging within the available parking window.
Used when charging time must be reduced further and site power supports higher DC output.
Used when turnover is high and charging windows are measured in minutes rather than hours.
These questions reflect the key concerns that usually come up during early DC project planning.
In low-traffic sites, a 20–30kW DC charger typically supports 10–30 vehicles per day, depending on charging time and vehicle battery size.
Compared to 22kW AC, DC charging avoids onboard charger limits and usually delivers a more stable and predictable charging speed.
Many 20–30kW projects can stay on existing low-voltage infrastructure, but available site capacity still needs to be checked before installation.
It works for small public sites with limited traffic. For high-turnover locations, higher DC power levels are usually required.
