Battery Sharing PlatformFeatures
S At RESC, Ltd., we aim to realize our vision of the "next-generation smart city" that is resilient to natural
disasters, is carbon-neutral and has widespread electric mobility. To realize the vision, we believe that
expanding and optimizing the use of batteries is essential, by fully utilizing the ICT system, prediction
algorithms and Big Data. Therefore, we have developed a unique digital platform named “e-Platform”
that enables battery sharing among users of various applications and scenarios (refer to Figure 1). Thee-Platform makes it possible to provide battery rental and swap services for e-Mobility users andenergy services that lead to smart grid constructions. Our patented ICT system*, designed withprediction algorithms, enables the maximization of user-convenience, economy, andenvironmental-friendliness for these services (*one of our PCT Patents: PCT/JP2019/025487).
S The target markets of the e-Platform are ❶ e-Mobility (e-Bike, e-Scooter, e-Motorcycle) and ❷ energy
storage. Their battery related problems, as well as solutions by battery sharing, are outlined in Figure
2.

Basic Concept or Summary
S Three primary constituent elements of the e-Platform are: ❶ ICT system (prediction algorithms, cloudservers, smart phone APP); ❷ e-Mobility; and ❸ battery related equipment (cassette batteries, battery
charging lockers).
S Processes for providing battery sharing services to e-Scooter users, which are progressively popular in
Asian countries, are outlined in Figure 3.

S Principal differentiating elements and advantages of the e-Platform are described in items 1 to 3 below:
1. Our battery charging locker is a charging station for swappable batteries and it also features anenergy storage function. This means that our battery charging locker not only charges internalbatteries, through remote control, initiated by our ICT system, but it is also capable of discharging(providing electric power) from internal batteries to external equipment and facilities. Our battery
sharing service, therefore, is not only suitable for e-Mobility applications, but also usable for energy
storage applications, such as constructing smart grids, the massive implementation of renewableenergy systems, as well as emergency power supplies.
2. Our competence is in prediction algorithms (Figure 4). Prediction algorithms can generally be madesophisticated through the utilization of internal and external big data and, as such, they ordinarily
have a significant impact on the performance of ICT systems. Our prediction algorithms utilize bigdata that encompasses users, traffic and weather conditions and are capable of making predictionson; ❶ the amount of solar power generated; ❷ the battery swapping demands of users, as well as;❸ the battery service life. Such predictions are used as the basis to optimize the charging(discharging) speed of batteries inside battery charging lockers in real time, from ICT systems.
Then, such optimizations lead to maximizing the use of renewable energy system-derived electricity
from solar panels near battery charging lockers or the power grid, to potentially maximize
air-pollution improvements and reduce CO2 emissions. It is furthermore possible to maximize highlevels of operational efficiencies (economy), for infrastructural equipment, by sustaining the safety
and user convenience of battery sharing services to a high standard.

We have already acquired multiple patents for ICT systems in several countries outside Japan,
including China. The series of technologies, know-how and ICT system patents are not limited toe-Mobility, but also intended for battery sharing services and battery replacement systems for
medium to large electric vehicles as well (Figure 5).
