KYOCERA and BYD Japan to collaborate on integrated energy system for EVs
05 June 2019
Kyocera Corporation and BYD Japan Co., Ltd., the Japanese arm of China’s BYD Co. Ltd., announced a joint project to develop an integrated renewable supply-demand energy system for EVs. By combining renewable energy from Kyocera’s solar power generating systems and BYD’s electric buses, the collaboration will maximize the effectiveness of renewable energy, greatly reduce power losses, and maintain a stable supply-demand energy balance.
For this project, Kyocera will develop the energy charge management system to optimally control the supply-demand balance between energy production and consumption by using aggregation technology developed during Virtual Power Plant (VPP) test projects over the past several years. This system will also incorporate the Kyocera’s renewable energy generating system.
BYD will supply two models of electric buses: K9, a large electric bus already available to the global market and J6, a compact electric bus specifically developed for the Japanese market which will be available in spring 2020. Additionally, BYD will use its technological expertise in developing electric buses and insights from energy consumers to consult on the project.
In verifying the effectiveness of the supply-demand integrated energy system for electric buses, Kyocera will also explore the potential of other renewable energy applications such as independent power systems for residential, transportation, and ride-sharing services in collaboration with local communities, power retailers, and transmission and distribution system operators.
Kyocera aims to demonstrate this energy system for EVs in 2020 with the goal of bringing it to market in 2021 after incorporating key findings from this collaboration with BYD.
There are no energy-storage elements other than the buses. What do they expect to do, keep the buses parked during the day so they can serve as sinks for the electric power that can't otherwise be used? Keep them partially discharged and on-line rather than fully charged and in service?
Unless there is a lot more to this scheme than is revealed in this press release, this is just more greenwash based on heavy doses of hand-waving.

Interesting to see that BYD is collaborating with a Japanese company.

This might work for school buses which are parked most of the day.

The buses listed are transit buses, not school buses.

A certain well known poster will soon be surprised when improved energy control systems will be installed to better automatically manage various energy production/demand sources.
Of course, those systems will use various REs sources and energy stored in BEVs and FCEVs and home storage units. Keyocera and BYD mays be the early leaders but many more will follow.
Better automated Energy management is needed to better use of massive increase in future REs and electrified vehicles, trains, drones, trucks, buses, boats, airplanes and ships. USA/Canada have fallen behind and will have to catch up.

And when the sun is asleep, is it charging power from the grid? Or, an out of service bus? or the grid? E-P is asking the right question.

The e-buses shown is just an example. In the real world it could be any one (or many) of the 3,000,000++ (soon to be 10,000,000+) extended range BEVs/FCEVs

At least commuter vehicles are likely to be plugged in during the peak of PV generation, and available as a sink to keep it from being thrown away.
