cpd-ocpp's Introduction

Open Charge Point Protocol 1.6

This repository contain abstraction layer for easy work with OCPP and validate input and output requests. Currently implemented only version 1.6 JSON. Whereas OCPP2.0 will support only JSON have no plans to implement SOAP.

Installation

npm install --save ocpp-eliftech

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);

cpd-ocpp's Issues

InternalError: Connectors not defined

I am having issues to get the StatusNotification payload. I wrote a simple charging point simulator and I always get an internal error when trying to send the StatusNotification.

[ 4, 0, "InternalError", "connectors is not defined", null]

My simulator is self-written (html using native in-browser WebSockets), but I get the same error using the chargingPoint.js in the examples folder of this repo.

[PI branch] Unexpected token import

Hi,

I tried to deploy your (awesome) proof of concept on a Pi 3 with raspian but when I run npm start I get a problem with the js import method.

Please let me know how to solve this issue.

Many thanks

update npm version

your package on NPM is out dated compared to the files here. Could you please push the update there?

Cannot find module 'babel-runtime/helpers/extends'

On npm start I get this error:
Error: Cannot find module 'babel-runtime/helpers/extends'

Maybe, dependencies has to be updated

Node v11.11.0

SetChargingProfile schema validation fails due to floating point arithmethic

the limit value is defined via multipleOf: 0.1 which will fail in many cases. When I set value of 0.1 everything is fine, else I will get an error, e.g. if I set 2000

Invalid value "[object Object]" for field csChargingProfiles

I think for validation purposes, the multipleOf requirement should be removed or the validator needs to be adjusted, else it makes it impossible to use the limit property.

babel-runtime is required but not a dependency

will throw if using this library as production dependency.

the const values in commands not exported by the ocpp-eliftech package

the ocpp-eliftech package at https://www.npmjs.com/package/ocpp-eliftech seems not export the consts defined in each command.

for example in the command StatusNotification, the consts like these are not accessible from codebase that is using this package.

export const STATUS_SUSPENDEDEV = 'SuspendedEV';
export const STATUS_FINISHING = 'Finishing';
export const STATUS_RESERVED = 'Reserved';
export const STATUS_UNAVAILABLE = 'Unavailable';
export const STATUS_FAULTED = 'Faulted';

SyntaxError: The requested module 'ocpp-eliftech' does not provide an export named 'OCPPServer'

Hi,

I have installed the OCPP module using "npm install --save ocpp-eliftech" and use the OCPP Server example in our index.js file as shown below :

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
};
}
}

When we run npm start then got error "SyntaxError: The requested module 'ocpp-eliftech' does not provide an export named 'OCPPServer'"

Please let me know how to solve this issue.

Finishing status not change using RemoteStopTransaction

Hi guys, i have a problem with status "finishing". When initialize a Remote Start Transaction and the is status is finishing not change status.

PD: EV left the parking bay and and the connector is disconnected.

net::ERR_INVALID_CHUNKED_ENCODING

When I toggle connectors on the chargepoint example, I get this in the console.

(index):1 GET http://localhost:9220/status net::ERR_INVALID_CHUNKED_ENCODING
Any idea why?

AssertionError [ERR_ASSERTION]: you must provide a joi schema

I am writing a simple chargePoint that sends a websocket to the centralSystem. I took the code from the examples and this is where I am facing issues with:

    const boot = new OCPPCommands.BootNotification({
      chargePointVendor: 'BrandX',
      chargeBoxSerialNumber: 'SR' + Math.round(Math.random() * 100000),
      chargePointSerialNumber: '123',
      chargePointModel: '12'
    });

    let answer = await client.send(boot);

OCPPCommands.BootNotification tries to validate the payload with applyPropertiesValidators and it failed to validate with Joi, specifically on this line:

// node_modules/ocpp-eliftech/node_modules/joi/lib/index.js
Hoek.assert(schema && schema instanceof Any, 'you must provide a joi schema');

This is what schema looks like before it fails the schema instanceof Any validation:

I am not sure if this is a dependency issue or there is something missing on my side. Any help would be appreciated.
