AC charging · the car converts
The point supplies AC and the onboard charger converts it to DC for the battery.
AC grid→EVSE→OBC→DC battery
- OBC phase count and power are decisive.
- Typical connector: Type 2.
PROFESSIONAL EV CHARGING
The right charger starts with the car, the grid and the available energy
7, 11 and 22 kW AC charging plus Sigenergy DC charging up to 25 kW. We design around the power the vehicle can actually accept, not the largest number in the catalogue.

BEFORE CHOOSING EQUIPMENT
Not every car charges at the same power
On AC, the vehicle onboard charger is a major limit. DC bypasses that converter, but the BMS, charging curve, temperature and state of charge still determine the result.
DC charging · the system converts
The module supplies DC through CCS2 to the vehicle battery system, bypassing the OBC.
Sigen Energy Controller→EV DC→CCS2→Battery
- Power follows the vehicle DC curve and BMS.
- Sigenergy requires Sigen Energy Controller.
Actual power ≈ lowest of available grid power, charging point, vehicle OBC or DC limit, and dynamic control
FOUR EXAMPLES THAT PREVENT MISTAKES
Charger power and vehicle capability must speak the same language
16 A single-phase OBC
Accepts about 3.7 kW. A 7 kW single-phase point will not raise the car above about 3.7 kW.
32 A single-phase OBC
Accepts about 7.4 kW. On an 11 kW three-phase point —16 A per phase— it normally uses one phase: about 3.7 kW.
16 A three-phase OBC
Accepts up to 11 kW. A 22 kW point does not double the speed: the car remains limited to 11 kW.
32 A three-phase OBC
May accept up to 22 kW. If the point or installation is limited to 11 kW, that is the maximum.
Indicative values for 230/400 V grids. Confirm the vehicle datasheet, phases, amperage, connector and charging curve.
FEATURED RANGES
Sigenergy DC up to 25 kW and Sigenergy and Atmoce AC
Three families for different needs. Rated power is only the starting point; compatibility, architecture and protection are validated per project.
INTEGRATED DC CHARGINGSigen EV DC Charging Module
12.5 or 25 kW CCS2 charging integrated into SigenStor architecture. It bypasses the OBC and coordinates charging with the energy system.
- 12.5 / 25 kW · 150–1000 V
- CCS2 · IP66 · cable length by reference
- Bidirectional charge and discharge up to 25 kW
- V2X depends on vehicle, standards and configuration
SIGENERGY AC CHARGINGSigen EV AC Charger
For homes, businesses and self-consumption, with mySigen control and dynamic management when the required sensor is integrated.
- 7 kW single-phase · 11 / 22 kW three-phase
- Type 2 · IP65 · indoor or outdoor
- Solar modes with SigenStor; dynamic control with Sigen Power Sensor

Preguntas frecuentes sobre carga de vehículo eléctrico
Respuestas para profesionales · Información actualizada el 13 de agosto de 2026.
¿Qué debe considerarse al elegir un cargador?
First identify the vehicle onboard charger: phases, amperage and maximum AC power. On AC, actual power is the lowest limit among installation, point, OBC and dynamic control. DC bypasses the OBC, but the vehicle BMS and charging curve still limit power.
¿Puede integrarse la recarga con fotovoltaica y almacenamiento?
Sí, siempre que la arquitectura y los equipos sean compatibles. El objetivo puede ser aprovechar excedentes, limitar potencia de red o coordinar la carga con horarios energéticos.
¿A quién suministra Plug & Play Energy estas soluciones?
La distribución y el soporte están orientados a instaladores y profesionales. El instalador estudia, ejecuta y legaliza la instalación conforme a los requisitos aplicables.
