We don’t only talk, we build!

Transparancy Prices Energy consumed Security

Distributed Ledger Technology Scalable Zero margin Sustainable

Contactor kWh meter Smart EVSE Intel NUC Socket

Initialization Establish connection with full node Establish serial connections (Smart EVSE, kWh meter, LED) 5-minute process to send energy consumption to the Tangle Initialize wallet (retrieve current balance)

Getting ready Generate new address Broadcast (self-transaction) state information Set LED color: yellow Start transaction loop Check transactions If there is one, start charging Otherwise, repeat again in X min

Receiving funds Check transactions Get transfers (iota.lib.js) Categorize (sent, received) Loop received If value transaction to my address Scan the bundle for a transaction positive value & not charge station Save that address (it is the customer’s). Return the value received Bundle Transaction 1: + 10 iota to B Transaction 2: - 1000 iota to A1 Transaction 3: 0 iota to A1 Transaction 4: + 990 iota to A2 A1: address 1 of customer A2: address 2 of customer B : address of charge station

Start of charging Set state to occupied Determine kWh with rate Send start command to EVSE Send start notification to customer Determine current kWh level Start kWh check loop

During charging Get current kWh level Compare it to what the customer paid for If its more or equal Send stop session command to EVSE Send end transaction notification to customer Send transaction information to customer Reset for next client Otherwise Send a status update if it has been X min since last update
