Nowhere else had created our ideal EV charger billing system.
We have therefore developed our own charging system.
This charging system is essential if installers are to make a profit.

Chapter 1. The reason for coming up with the product or service, lack of something, problem

Dissatisfied with the fact that the amount of money is set by charging time or per charge,regardless of how many kW output the charger has,and that it can only be used if a monthly fee is paid, the development staff wondered if a fee system could be created based on the amount put in,like at a petrol station.
The per hour, per charge system is not fair,as the charge is the same whether charging at 20 kW or 50 kW.

Chapter 2. Emergence of partners, rivals and mentors; trials, setbacks and reinvention; successes; rewards.

There was a legal barrier to establishing a per kW billing method.
For a billing system per kWh of electricity used, it is necessary to measure the amount of electricity using measuring instruments that have passed verification in accordance with the provisions of the Measurement Law.
The payment method is a credit card, which can be used without paying a monthly fee.
Dozens of companies searched for a system that would allow payment by credit card or IC card.

Chapter 3. Contributions and repercussions for society brought about by the second chapter, and the beginning of the next storyline.

The new charging method has created new possibilities for EV chargers. With the previous system, there was little profit for the installer and it only attracted and appealed to customers.
However, the fees can now be set freely.
If a charging model could be established that does not go through the NCS, it would be a good investment.
Purpose of attracting customers, parking management.
For people to want to install fast chargers, they have to make it profitable to install chargers.
This will further spread EVs throughout Japan and complete Japan as an environmental superpower.

Furthermore, in the future, EV chargers will be used to revitalise depopulated areas.
Electric vehicle owners can usually charge at home, but "want to charge when they go away" : "revitalisation of rural areas." Demand is rather high in depopulated areas. Use of idle land , can be done regardless of location.
