ON Semiconductor joins CharIN Ecosystem

ON Semiconductor has joined the global Charging Interface Initiative (CharIN) ecosystem, which aims to promote standards for charging systems in electric vehicles (EV).

Ali Husain, ON Semi’s senior manager of power conversion and motor control, said: “We are seeing a ramp up of our IGBT modules and FETs for electric vehicle charger designs. We expect next generation semiconductor materials, such as silicon carbide and gallium nitride, to drive improving power density and efficiency.”

CharIN was founded by Audi, BMW, Daimler, Mennekes, Opel, Phoenix Contact, Porsche, TÜV SÜD and Volkswagen. It now has more than 60 members. The group says it has three primary aims:

  • To develop and establish the Combined Charging System (CCS) as the standard for battery-powered EVs of all kinds
  • To draw up requirements for the evolution of charging-related standards and develop a certification system
  • To promote the CCS standard worldwide

The CCS specification combines single phase and rapid three phase charging using AC at a maximum of 43kW, as well as DC charging at up to 200kW. The approach is also said to be taking into account the ability to charge at up to 350kW.

The specification also includes the connector and inlet combination, as well as all control functions and communications between the EV and the infrastructure.

Husain added that ON Semi intends to collaborate with other industry leaders to create a CCS and ‘support the continued evolution of EV charging infrastructure’.
