Description

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:

  • V2G (Vehicle to Grid): Vehicle to grid. That is, electric vehicles can not only obtain electrical energy from the grid for charging, but also feed back the electrical energy in the vehicle battery to the grid under certain circumstances to realize reverse transmission of electrical energy. This helps to peak-shave and valley-fill the grid, improve the stability and efficiency of the grid. At the same time, vehicle owners may also obtain certain economic benefits.

  • V2L (Vehicle to Load): Vehicle to load. It can use electric vehicles as a mobile power source to supply power to other external load devices. For example, when camping outdoors, it can supply power to electric ovens, stereos and other devices, expanding the usage scenarios of electric vehicles.

  • V2H (Vehicle to Home): Vehicle to home. It enables electric vehicles to be connected to the home's power system and provide emergency power for the home in case of power outages or charge at low electricity prices and supply power to the home at peak times to save home electricity costs.

     

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

  1. 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".

  2. 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".

  3. 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".

Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I
