Our continuous research and testing approach means Sara’s been designed with people like you, for people like you.
As they get connected to your network, Sara automatically adds new stations. You activate them, and add any extra information you need.
See and manage your stations however makes sense to you and your business model. Organise by location, tags, customers, or make and model.
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.
Sara's in-depth error diagnostic functionality notifies you of any potential issue, before a charger component fails.
Sara gives you a human-friendly view of where problems are, through rich message logs and contextual info about each message.
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.Book your tour →
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.Book your tour →
There’s no one size fits all. With Sara’s AI-powered dashboard, you can customise your analytics overview – giving you valuable business insights, right at your fingertips!
You can also create reports on just about anything, which will help you make strategic operational decisions, such as where and when to get new chargers - reducing costs, and boosting revenue.Book your tour →
Sara’s intuitive interface is easy-to-use, so day-to-day tasks like onboarding new stations, adding a tariff and fixing any issues with remote actions are simple. Sara is helping you every step of the way, so you can focus your effort on best-in-class charging sites and services.
Sara’s automation, predictive maintenance and diagnostics capabilities mean that the biggest cost in charging operations – sending out maintenance workers – is significantly reduced. It also reduces site owner costs thanks to smart charging and vehicle-to-grid features.
Sara highlights network issues and malfunctions for proactive trouble-shooting. With accurate, real-time data on things like occupancy, charge power and opening hours available through roaming, you can better serve your EV drivers.
See how drivers use your chargers, so you can make data-led decisions on where to invest in your network. Some chargers in constant use? Maybe you could install more to create a better driver experience and increase revenue. Some chargers barely used? Maybe the site isn’t attractive to drivers, and you could install a canopy to protect them from the rain.
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.
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.
This plug-in aggregates hundreds of EVs into a virtual power plant to provide ancillary services to the grid when needed.
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.
Sara also makes it easy to integrate with other systems like CRM and invoicing software through our open APIs.
Cutting-edge technology that gives you a hi-definition insight into every part of each charging event — from the car, to the grid and through every detail of your network.
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 stands for Station Analytics and Remote Administration
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.
Continuous Integration / Continuous Deployment (CI/CD)
Scotti stands for Simple Compliance Testing Tool for Interoperability.
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.
The Message Queuing Telemetry Transport (MQTT) is a lightweight, publish-subscribe network protocol that transports messages between devices.
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).
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.
Power line communication, a communication technology that enables sending data over existing power cables.
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.
Charge Point Operator, the entity monitoring and managing an EV charger network.
