Japan’s CHAdeMO association has released a new protocol supporting current electric vehicle fast charging and upcoming 200-mile plus electric cars.

During CHAdeMO’s annual General Assembly in Tokyo, the association announced an amendment to the current protocol that will enable 150 kW power transfer. The first installations are expected in 2017, with full compatibility with CHAdeMO-compatible electric vehicles out on the roads.

The CHAdeMO standard allowed up to 100 kW in power transfer. That only applied to a small number of charger installations, with most of them having been set up in the 40-60 kW range. The new 150 kW power transfer capability will be possible at 350 A current for new long-range 200-mile-pus electric vehicles. The chargers will be designed to accept power from new fast chargers, while older EVs will be able to charge at a lower rate.

The new standards will be of interest to automakers and EV owners looking forward to 200-mile range affordable electric cars coming to market. As for EVs in the product pipeline, the 2018 Hyundai Crossover SUV and the next-generation Nissan Leaf are expected to offer 200-mile-plus electric models. Both Hyundai and Nissan endorse using CHAdeMO fast-charging standards, while competitors from North America and Europe use the Combined Charging Standard (CCS) combo protocol.

“One of the purposes of the Association is to evolve CHAdeMO protocol so that it can better respond to market needs,” said CHAdeMO’s Secretary General Dave Yoshida. “We see a movement towards mass market EVs with higher capacity batteries and we, as the Association of fast charging protocol, prepare for it by working on the high power protocol. This will enable faster deployment of the high power charging infrastructure, in preparation for EVs that can charge with higher power.”

CHAdeMO said that another engineering issue was addressed during its annual meeting. Technical studies are being done on 350 kW power capacity, which would put CHAdeMO on a competitive level with plans being worked on by the CCS combo alliance. The CHAdeMO association will determine its potential development around 2018, should there be market demand.
