1. Proof of Concept
IOTA Charging Station

2. researches and tests the possibilities for Smart Charging

researches and tests the possibilities for Smart Charging

3. We don’t only talk, we build!

4. Transparancy
Prices
Energy consumed
Security

5. Distributed Ledger Technology
Scalable
Zero margin
Sustainable

8. Contactor
kWh meter
Smart EVSE
Intel NUC
Socket

9. 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)

10. 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

11. 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: iota to B
Transaction 2: iota to A1
Transaction 3: iota to A1
Transaction 4: iota to A2
A1: address 1 of customer
A2: address 2 of customer
B : address of charge station

12. 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

13. 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
