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 16-24kWh batteries, becomes not so fast when the battery size reaches 40, 60 or more kWh. To meet the expectations of the e-mobility stakeholders and drivers, CHAdeMO is working on high power charging. A new edition of CHAdeMO protocol enabling 200kW charging was developed by the Association and its members.

High Power roadmap

Publication of 200kW protocol
CHAdeMO protocol enabling charging with 100kW continuous power/ 150-200kW peak power (400A x 500V) was published

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
350-400kW charging enabled via multi-stand, power share type of chargers, charging with 350-400A and 1kV

CHAdeMO 200kW specification

While 200kW 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

SAFETY FOR OVER-TEMPERATURE
  • Sensor and/or fuse in the gun
THRESHOLD OF CABLE TEMPERATURE
  • Part to be touched: below 85°C
  • Part to be held: below 60°C
CABLE TEMPERATURE CONTROL
  • Thermo-sensor at gun and/or cable
  • Direct current control by sensor feedback
