High Power

EV batteries are getting cheaper and cheaper encouraging OEMs to put more battery capacity in their vehicles. However, what is fast charging for 20-24kWh batteries, becomes slow charging when the battery reaches 30, 40 or more kWh. To meet the expectations of the e-mobility stakeholders and drivers, CHAdeMO is working on high power charging. An addendum to CHAdeMO protocol enabling 150kW charging was developed by the Association and its members.

High Power roadmap

Publication of 150kW protocol
CHAdeMO protocol enabling charging with 100kW continous power/ 150-250kW peak power (350A/ 500V) was issued to Regular Members

1st high power chargers deployed
CHAdeMO expects 1st certified high power chargers to be deployed in 2017, on key corridor routes
Development of 350-400kW charging protocol (TBD)
350-400 charging enabled via multi-stand, power share type of chargers, charging with 350-400A and 1kV

CHAdeMO 150kW specification

While 150kW means a significant change of charging speed for EVs with high capacity batteries, it does not require a lot of changes in the protocol itself. The main changes concern the connector and not the charger body or charging specification.

Changes to the connector

  • Sensor and/or fuse in the gun
  • Part to be touched: below 85°C
  • Part to be held: below 60°C
  • Thermo-sensor at gun and/or cable
  • Direct current control by sensor feedback
