        # corrently-charge



**Corrently Charge is a full automated tariff evaluation process. It automatically chooses different tariffs to the client depending on final state of charge, available time and energy mix. Selected tariff requirements are fulfilled via a scheduler connection to CPO's backend (via OCPP protocol). The solution Corrently Charge acts as an intermediate between a given energy management system and the charge point.**

## Challenge

Todays BEV charging lacks communication between driver/customer and charge point operator (CPO).

*If we would know the goals the driver has by time of connecting to our charging point, we could optimize the charging session, for the driver, for us and for the environment.*

### Goals

- integrate local generation (eq. photovoltaics) into tariffs

- reduce scope2 greenhouse gas emissions for customers

- ensure regulatory compliance   

- consult clients using data driving transparency

- expedite adoption of eMobility by providing  state of the art CX

### Problem definition

The flexibility of BEV charging for demand-side-management could not be used in public or semi-public charging points. Local energy generation in conjunction with eMobility do not develop synergy effects making investments into energy management less attractive and limiting customer experience in an upcoming competitive market.

### Proposed solution

Automated tariff evaluation as soon as charging session starts. Tariffs take local generation and green power index into account giving different tariffs to the client as options of required energy (final state of charge), available time, energymix.

Selected tariff requirements are automatically fulfilled via a scheduler connection to CPO's backend (via OCPP protocol). The sollution corrently-charge acts as an intermediate between a given energy management system and the charge point.

Core of the solution is encapsulated into an Open-Source Node Module [NPM](https://www.npmjs.com/package/corrently-charge) allowing to quickly adopts new tariff models or limit number of available models based on requirements at a certain location.

### Business Model Canvas

[![Business Model Canvas](./EnPulse_BusinessModelCanvas.png)](./challenge/bmc.pdf)

Or [browse GIT](./challenge/slides/BusinessCanvas_CorrentlyCharge.htm.html)

### [Working prototype](https://smith.corrently.cloud/app/mobilitython-corrently-charge/tariff-selection-631dc4f8caf77e03f003740b)

This prototype takes a real charging station located in the village Mauer (Germany) and uses the prediction of a PV power plant at the same grid connection point as local energy generation.

**Configured prices**

| Price per kWh | Source |

|---|---|

| 0.75€ | Mains / public grid |

| 0.30€ | PV / local generation |

## Architecture / Integration Points

[![Architecture Schema Charging](./challenge/architecture.drawio.png)](./challenge/architecture.drawio.png)

[Download draw.io xml](./challenge/architecture.drawio.xml)

## Installation

```

npm install --save corrently-charge

```

## Configuration

Either as  `.env` or during instanciation

| Setting | Description |

|---|---|

| `SOLAR_PREDICTION` | URL to the solar prediction API to use |

| `GSI_PREDICTION` | URL to the Green Power Index API to use |

| `localPrice`  | Price per kwh for local energy (eq. solar) |

| `gridPrice`   | Price per kwh for energy from grid |

## Limitations

- Does not respect none-linear maxpower

- Does not respect reactive power in low power charging conditions
