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
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
