EV charger management for tomorrow’s charge point operators

Sara supercharges your charging network: giving you the tools, data and insights to shape a network that works for your drivers. You get unprecedented access to every single detail of a charger event, from car, to charger, to grid, and total control over your network, whether it’s a hundred stations or thousands.

built for you

Tooling for management and maintenance that’s built around people first

Our continuous research and testing approach means Sara’s been designed with people like you, for people like you.

Automated charger onboarding

As they get connected to your network, Sara automatically adds new stations. You activate them, and add any extra information you need.

Flexible network set-up

See and manage your stations however makes sense to you and your business model. Organise by location, tags, customers, or make and model.

Simple tariff settings

Set multiple tariffs and create your own tariff rules. You can follow wholesale market prices and add your own profit margins. Sara also warns you about conflicting tariffs on a station.

Remote diagnostics and maintenance

Sara's in-depth error diagnostic functionality notifies you of any potential issue, before a charger component fails.

Reader-friendly error messaging

Sara gives you a human-friendly view of where problems are, through rich message logs and contextual info about each message.

high-definition

Better data, happier customers

Gone are the days of reactive management with Sara. The deep-dive view, facilitated by the advanced device management (OCPP 2.0.1), lets you see every single component of your station.

The data you gather about your stations over time also teaches Sara’s AI about your network and its risks. So you know exactly what’s happening in real time, and can get ahead of problems before they get ahead of you.

granular detail

Get the full picture and let drivers know exactly what is going on

Sara analyses the conversation between the EV and the charger at each transaction.

This alleviates the black box and lets you share with drivers exactly what has happened if an error occurs, even when the issue stems from the EV. You can then take steps to resolve the issue for your customer by sharing rich error messages on the charger display.

Why choose Sara?

customisation

Introducing the Sara App Store

Drivers want different things, and you build your business to cater to their needs. So your charging management system shouldn’t be a one-size-fits-all.

Sara is the central hub that manages chargers via OCPP, connects to mobility service providers via roaming protocols, and talks to the grid operator for sensible smart charging.

We’ve also built Sara with an open API approach so you can easily integrate plug-ins. Our vision for a future-proof CSMS lets you build your services on top of our open, API-first platform.

Smart load management app

The smart load management plug-in lets you manage the energy demands of your stations. Plan charging sessions in advance or at EV arrival times to reduce peak loads, energy costs and CO2 emissions.

Predictive maintenance app

The data you gather about your stations over time teaches Sara’s AI about your network and its risks. With this plug-in you can even predict where faults will occur and fix them before they appear.

Virtual power plant app (V2G service)

This plug-in aggregates hundreds of EVs into a virtual power plant to provide ancillary services to the grid when needed.

24/7 support

We have a partnership with a dedicated team of specialists who are on hand to help and fix any issue drivers might come across when they use your network, offering 24/7 customer service support.

CRM and invoicing software integration app

Sara also makes it easy to integrate with other systems like CRM and invoicing software through our open APIs.

why switch

Device Management
DEF:
Device Management

With OCPP 2.0.1 and the new device model concept, a station can automatically describe its full layout and capabilities to the cloud-based CSMS. This allows for plug-and-play installation of a charging station. It also lets the CSMS read and control any component remotely.

Sara
DEF:
Sara

Sara stands for Station Analytics and Remote Administration

OCA
DEF:
Open charge alliance

The Open Charge Alliance is the official body that specifies OCPP 2.0.1 and defines a set of certification profiles. Each profile tests a certain set of functionalities. Depending on the functionality of your charger or CSMS, you might want to certify for either a subset or all of these profiles.

CI/CD

Continuous Integration / Continuous Deployment (CI/CD)

Scotti
DEF:

Scotti stands for Simple Compliance Testing Tool for Interoperability.

EXI
DEF:
Efficient XML Interchange (EXI)

Efficient XML Interchange (EXI) is a very compact representation of XML. All ISO 15118 messages are defined in XML. EXI improves serialisation and parsing speed on embedded devices (like an EV and a charging station controller) and allows more efficient use of memory and battery life, compared to standard (textual) XML.

MQTT
DEF:
Message Queuing Telemetry Transport (MQTT)

The Message Queuing Telemetry Transport (MQTT) is a lightweight, publish-subscribe network protocol that transports messages between devices.

CSMS
DEF:
Charging Station Management System (CSMS)

A CSMS is a cloud-based management system operated by the company that is managing the charging stations. A charging station connects to a CSMS using OCPP (Open Charge Point Protocol).

ACD-P
DEF:
Automated Connection Device (ACD)

Automated Connection Device (ACD), a conductive charging concept that doesn't require a person to plug in the charging cable. A first implementation is ACD-P, where 'P' stands for 'pantograph' charging of buses.

PLC
DEF:
Power line communication (PLC)

Power line communication, a communication technology that enables sending data over existing power cables.

SLAC
DEF:
Signal Level Attenuation Characterisation (SLAC)

Signal Level Attenuation Characterisation (SLAC) is based on power line communication (specifically HomePlug Green PHY) and is a protocol to establish the data link between the EV and the charging station via the charging cable.

CPO
DEF:
Charge Point Operator (CPO)

Charge Point Operator, the entity monitoring and managing an EV charger network.
