Tokyo: Fujitsu Limited and venture start-up RESC, Ltd. recently announced that they have agreed to collaborate in developing an infrastructure system that integrates the fields of ICT and energy to help bring about a new electric vehicle society.
Under this agreement, the portable cassette-type secondary batteries used in RESC’s electric scooters and the charging lockers that recharge them will be managed and analyzed by Fujitsu’s cloud service that employs location data, the Fujitsu Intelligent Society Solution SPATIOWL. This will make it possible to monitor travel-related information, such as road traffic and vehicle statistics. Information on when the scooter batteries need to be charged, when they need to be replaced, and information on the location of replacement batteries and charging lockers, which are spread out in a variety of locations will also be available.
Given the further growth in demand anticipated for electric scooters, Fujitsu and RESC seek to help bring about a society in which renewable energy is utilized by using ICT to allay concerns about battery charging and replacement. As a first step, by 2015, they plan to roll out electric scooters with these batteries to delivery companies, along with the infrastructure system described above, building the foundation for a society in which electric vehicles are ubiquitous. By 2020, the system will be available to the general public.
By integrating ICT and energy fields, Fujitsu and RESC will build a new system that can manage and analyze batteries. By managing each battery as a separate unit, the system can keep track of its remaining charge, deterioration, and location, bringing the following benefits
- Electric vehicle users will be able to use batteries that are in good condition.
- Personnel in charge of batteries can track the utilization of each one to manage resources efficiently.
- Battery usage by individual users can be ascertained, thereby allowing for multiple users to share more than one battery. This makes it possible to utilize the service based on proper operating costs in line with actual usage.
Scooter riders can connect their smartphones to the batteries via Bluetooth and use a Fujitsu-developed app on their smartphone to monitor the remaining charge on a battery and its remaining useful life. Battery data is sent via the Internet to a big-data center for storage and analysis, which will predict when a battery needs to be replaced and will automate the management and use of deteriorated batteries so that batteries needing maintenance are not used.
2. Manage locations for charging lockers and charging status in real time
Scooter riders can use their PCs or smartphones to look up, in real time and together with positioning information, the charging status data of individual batteries aggregated from charging lockers.
3. Predict distance current battery will be able to run, and search for and reserve battery replacement locations
Scooter riders can check the distance they can travel on their electric scooters based on predictions of remaining battery charge and when the battery needs to be replaced. They can also use their smartphones to search for battery replacement locations around that distance along their journey and reserve a battery replacement.
