4.1.3. Smart Billing System (SBS)

To calculate the amount of charge transferred from an HCS to an EV, a proper measurement system is used named SBS. SBS calculates the amount of charge in kilowatts (KW) and determines the amount to be paid according to the price asked by the HCS. In the proposed system, a smart meter is used to calculate the amount of charging, and the HCS will share it using the blockchain. As members of the blockchain, all the EVs and HCSs are connected to the blockchain by using a cryptocurrency. Once all calculations are done and fixed, the amount will be automatically deducted from the EV's account and then credited to the account of the HCS.
