360~480kW Distributed Charger

From a charging station view, benefits of Distributed Charger

• 

  Flexible charging for different application scenarios: Flexible deploy user terminal, flexible deploy power, adapt to individual application of urban hub, declinational charging hub, highway hub, adapt to vehicle, bus, truck.

• 

  Small and attractive: The user terminal has small footprint which can maximize parking area, it also has attractive appearance to provide better esthetics for the charging station.

• 

  Low noise: Power bank is the noise resource and can be placed away from users.
  The noise of liquid cooled user terminal is <55dB, air cooled user terminal is close to 0 dB

High speed charging

• 

  10 minutes charging

• 

  400 kilometers driving

• Ultra fast charging for Liquid cooling charging，500A current 800V voltage，400kW power 10mins charging 500A*800V*10/60H*0.96=64kWH
• Fast charging for standard charging mode, 450V vehicle，200A current, 400V, 80kW power, a power bank pumps 6 user terminals at full power

Flexible matrix power switching

With flexible matrix power switching technology, vehicle can charge with 100% accurate power requirement and the capacity of power bank can be 100% used. This is the highest operating efficiency.

• What is the flexible matrix power switching 24*20kW power modules in the power bank are split into 12 sets, each set has 2 power modules with 40kW charging power. These 12 sets charging power can be dynamically allocated to user terminals and distribute power according to different charging needs.
• The benifit of matrix power switching In the different SOC periods, requirements of charging power are different. 40kW charging power as a unit to fulfill various charging needs and provide 100% accurate charging power at “maximum power”. Multiple user terminals share one 480kW power bank whch makes high efficiency operation of EV charger and EV charger station.

Higher power conversion efficiency to improveprofitability of EVC station

• Power conversion Independent research and development of the power module, equiped with the third generation SiC MOSFET semiconductor with higher efficiency and three-level Vienna topology. The high perfomance of the device and the topology enable the peak efficieny of power module to reach 96.5%.
• System active efficiency optimization The distributed charger integrates the distribution system for control of 24pcs power modules in the power bank to ensure 50% load rate of power conversion module and 96% efficiency of the charging system. Compared with 95% efficiency, taking 6 vehicles charge with 80kW as an example, each 480kW EV charger can reduce energy loss of 5.26kWh per hour and is able to save 11519kWh electric energy every year for charging 6 hours a day.
