Compact design with a reduced number of power electronics components and the cascading level of the power electronic modules

Challenge market of electric vehicle drive systems

  • The global smart electric-drive component market is projected to grow at a CAGR of 31.74% reaching USD 3.5 billion by 2022 from 889 million in 2017. In terms of volume, the market is estimated to reach 2.206.604 units by 2022 from 528.241 units in 2017 (Market&Markets)
  • Generally, there are two types of electric vehicles (EVs): vehicles using only an electric motor as a drive source, and hybrid vehicles including an electric motor and an engine as drive sources
  • Any type of electric vehicle has a battery as an electricity storage device for supplying electric power to the electric motor, and when the remaining capacity of the battery decreases, the battery may be charged from a source external to the vehicle
  • A drivetrain of an electric vehicle may comprise a charger unit, a battery, a DC/DC converter, and a DC/AC inverter coupled to an electric motor that produces the power for driving the wheels of the vehicle
  • The charger unit, the battery, the converter and the inverter are typically cascaded in series in the drivetrain
  • However, this cascaded arrangement may reduce the overall operation efficiency of the electric vehicle
  • Need for improved power electronics modules for electric vehicles

The new design of electric vehicle drive

  • Novel design of multipurpose power electronics module for the new generation electric vehicles
  • The proposed module is designed for plug-in hybrid electric vehicle (PHEV) with series-parallel powertrain, and battery electric vehicle (BEVs)
  • One module with single stage conversion to perform all tasks: V2G, G2V, propulsion, regenerative braking
  • Eliminating the need of an extra charger module between the grid and the care for level 1, 2, three-phases AC, and fast charging
  • Prototype available
  • Technology developed by Prof. Pragasen Pillay and Tamanwè Payarou at Concordia University

Competitive advantages

  • A single, robust, low cost and modulable design
  • Compact design with a reduced number of power electronics and the cascading level of the power electronic modules
  • Improved powertrain efficiency and performance
  • Level 1, 2, three-phases AC V2G, G2V, and fast charging with the same module

Interesting market applications 

  • Plug-In electric vehicles (PHEVs)
  • Battery electric vehicles (BEVs)

Business opportunity

  • Technology available for licensing
  • Provisional patent application filed
