Product overview
This BI-DIRECTIONAL DC Fast Charger supports three major modes: V2G (Vehicle-to-Grid), V2L (Vehicle-to-Load), and V2H (Vehicle-to-Home), redefining electrical energy interaction. With V2G technology, vehicles can charge during low-power consumption periods and feed power back to the grid during peak hours, aiding in peak shaving and valley filling while generating revenue. In V2L mode, the charger transforms into a high-power mobile power source, providing stable electricity for camping equipment, outdoor machinery, emergency rescue gear, and other loads. The V2H function enables electric vehicles to serve as home backup power, ensuring household appliances operate during power outages or optimizing home electricity costs. Supporting a maximum charging power of 350kW and discharging power of 100kW, it is equipped with an intelligent power regulation and bidirectional energy management system to ensure efficient, stable, and safe bidirectional power transmission, making it a core device for the future smart energy ecosystem.

Bi-directional function:
what is V2G technology? In short, it is based on two-way charging piles, combined with energy management systems and cloud platform intelligent scheduling technology, and connected to the power grid dispatching system to realize the intelligent two-way transmission of electrical energy between the power grid and vehicles, meeting the purposes of vehicle transportation, new energy access, and stable control of the power grid.
Application scenarios
Grid-side V2G peak shaving
Adaptation advantages: Supports charging during off-peak hours and discharging during peak hours (100kW discharge power), helping the power grid balance loads; can be connected to the grid dispatching platform, suitable for power companies and new energy vehicle companies to build "virtual power plants"; covers long-tail keywords such as "grid peak shaving V2G charging piles" and "virtual power plant bidirectional charging and discharging equipment".
Home V2H emergency backup
Adaptation advantages: IP54 protection allows installation on balconies/garages, with a temperature resistance range of -40℃~+75℃, suitable for both northern and southern regions; automatically switches to V2H mode during power outages, with 40kW power capable of supporting a refrigerator (0.8kWh/day) + air conditioner (1.5kWh/day) to work continuously for 3 days; covers "home V2H charging piles" and "power outage backup bidirectional fast charging piles".
Outdoor V2L power supply (camping/emergency)
Adaptation advantages: 5m cable + IP54 waterproof, suitable for campsites and outdoor construction; V2L mode can power electric drills (1.5kW), portable ovens (2kW), and emergency lighting, replacing fuel generators; covers "outdoor V2L charging piles" and "camping vehicle-mounted power supply equipment".
It supports GBT/CCS1/CCS2/CHAdeMO/Tesla connectors, compatible with most EV models (e.g., BYD, Tesla, Volkswagen).
With 40kW output, it can power a family (refrigerator + lighting + router) for 3-5 days, or with air conditioning for 1-2 days.
Supporting bidirectional energy transmission between the power grid and load, capable of storing electricity during off peak periods and discharging during peak periods, utilizing peak and off peak electricity price arbitrage, and serving as an emergency power source; Adapt to low-power scenarios with limited space and power distribution .
