Overview

Open Charge Point Protocol (OCPP, http://www.openchargealliance.org/) is a communication protocol between multiple charging stations ("charge points") and a single management software ("central system").

Usage

Server

import { OCPPServer, OCPPCommands } from 'ocpp-eliftech';

const server = new OCPPServer();

server.listen(9220);

server.onRequest = async function(command) {
    // Handle different commands
    if (command instanceof OCPPCommands.BootNotification) {
        return {
            status: 'Accepted',
            currentTime: new Date().toISOString(),
            interval: 60
        };
    }
}

Client

import { OCPPClient, OCPPCommands } from 'ocpp-eliftech';

const client = new OCPPClient({
    serverUrl: 'http://localhost:9220/webServices/ocpp/CP1111'
});

await client.connect();

const boot = new OCPPCommands.BootNotification({
    chargePointVendor: 'BrandX',
    chargeBoxSerialNumber: 'AQ1234VB5678',
    chargePointSerialNumber: '123',
    chargePointModel: '12'
});

let answer = await client.send(boot);
console.info(answer);
