PRE Power Developers starts mass production of V2G charger module (with direct solar charging option)

2019 will be the year (commercial) V2G charging will definitely break through. In 2018 the first demonstration and qualification projects have been finished successfully. 2019 will continue in this fashion. PRE Power Developers develops and produces charger modules for manufacturers of charging stations. In 2018 the development of the 10kW bidirectional V2G charger module was completed. PRE has setup a strong supply chain and is ready for mass production to fulfil in the surging demand.

The concept of V2G

We are just one step away from the EV era. In this era there will be a lot of batteries on the road. Or actually, parked since most vehicles are only driving 10% of the time. The remaining time they are parked at home or at work. The V2G concept envisions the use of the EV batteries as a virtual power plant. This concept can not only be used for your home, but also for a nation or even a whole continent. The batteries of Ev’s and other energy containers will be joined together to become a virtual, very dynamic and flexible power supply.

 

 

Direct solar charging

Electric vehicles are seen as the sustainable future of transport. However, they are only truly sustainable if the electricity used to charge them, comes from sustainable sources and not from fossil fuels. Sustainable sources such as solar panels can be used well for charging. Currently the charging of electrical vehicles is always via the power network. Direct current (DC) of the solar panels is converted into alternating current (AC) for the electricity grid and the AC of the electricity grid is converted back into DC for the battery pack of the car. A small 10% of the energy is lost in both conversion steps: a total of 19%. For this reason, PRE developed a charger module with solar option that allows for the direct charging of electric cars using solar panels, even without a main grid connection.

 

 

V2G Vehicle to Grid Module

The PRE V2G charger module is a bidirectional AC-DC converter. As a result, the energy from the battery can also be used to deliver back to the grid (Vehicle to Grid). The charger module can handle four different power flows:

  1. from solar panels to electric vehicle
  2. from electric vehicle to the grid
  3. from the grid to electric vehicle
  4. and from the solar panels to the grid

 

The V2G 10kW charging module is a smart integration between an MPPT solar module and an EV charging module. The modules can be used modularly, making it possible to place the modules in parallel to achieve a power of 150 KW. Due to the integrated solution, fewer components are required, the power density is three times higher, resulting in much lower costs. By using silicon carbide and quasi-resonant technology, efficiency of more than 96% is achieved for both full and partial loading. PRE is ready for mass production of the V2G charger module.

 

 

The V2G 10kW charger module features:

  • CCS & CHAdeMO compliant.
  • Bidirectional (V2H/V2G) Operation.
  • CANbus Control Interface.
  • Latest Resonant Technology
  • High efficiency up to 98%
  • Direct Solar Charging with optional PV Input.
