Station Analytics and Remote Administration is the only charging station management system that is built with ease-of-use and future-proof standards at its heart.
We built Sara to make managing and monitoring charging points easier and more effective. Sara gathers valuable, intelligent, and accurate data, which gives you the most up-to-date information on your network and allows you to run it smoothly. Its user-centric design allows you to easily harness the full monitoring and management capabilities of OCPP 2.x and ISO 15118.
Whether you operate hundreds or thousands of charging stations, with Sara's powerful control centre you always keep a perfect overview and can assign roles and access rights for each activity and person.
Sara’s features are split into three different types of activities:
If any errors occur, Sara instantly notifies you on customisable channels. These errors are categorised by severity. Highlighted network issues and malfunctions for rapid and proactive trouble-shooting can be allocated to specific engineers.
Sara's in-depth testing and error diagnostic functionality is powered by Scotti, our own compliance testing tool. This significantly decreases the engineering cost and effort to both onboard a new charger and to diagnose any problem that may arise later on during its operation.
Easily view and manage your stations in a way that makes sense to you and fits your business model. Create groups of stations by location, by customer or by type of station, for example.
As they get connected to your network, Sara automatically adds new stations to your list of stations. All you have to do is activate them, and add any additional information as you see fit.
Remotely monitor and manage your stations in the most cost-effective and sustainable way. When an EV needs to be charged, Sara takes into account its energy needs and the state of the local electricity grid, before assigning it the appropriate charging profile. This smart way of charging reduces overall costs and harnesses as much renewable energy as possible.
With OCPI (Open Charge Point Interface) and Hubject’s OICP (Open InterCharge Protocol) already implemented, we can act as a CPO on your behalf. You can benefit from our agreement with Hubject, or define your own bespoke agreements with other roaming partners.
Quickly identify problematic transactions before the EV driver notices with Sara's transactions alerts. You can also see all ongoing transactions and filter them by category with Sara's powerful search function.
Sara also takes care of creating the bill for EV drivers’ mobility service providers, based on the transaction details and the tariffs that apply to each transaction.
Sara allows you to set different tariffs on your stations, and create your own tariff rules. Our simple interface allows for multiple combinations of kWh pricing, session fees, and time-of-use pricing. It also alerts you if there are any conflicting tariffs.
With a software that’s so user centric, we wanted to provide nothing short of superior, around-the-clock customer support. This is why we chose to collaborate with EVA, a specialised, dedicated team of service providers who are on hand to help and easily fix any issues, anytime of the day.
Sara is designed with an Application Programming Interface (API) first approach. This means we provide an API that allows you to build innovative features that plug into Sara, and even integrate it with other tools that boost your productivity, such as CRM and accounting software.
Sara can create reports on just about anything – what are the most common faults in my network? Which components of a charging station need to be replaced? Which chargers bring in the most revenue? These will help you make strategic operational decisions, such as where and when to get new chargers.
There’s no one size fits all. Sara’s
AI-powered dashboard allows you to customise the analytics overview to whatever you like – giving you valuable business insights, right at your fingertips.
Sara’s intuitive, easy-to-use interface makes it easier and quicker to complete day to day operational tasks. Basic tasks, such as onboarding new stations are mostly automated, which gives you more time to focus on other areas.
Sending out maintenance workers to fix a problem at a charger is the most expensive part of operations. With automation, predictive maintenance, and diagnostics, Sara significantly lowers operational costs. It also reduces site owner costs thanks to smart charging and vehicle-to-grid features.
Sara highlights network issues and malfunctions for rapid and proactive trouble-shooting. With accurate, real-time data on chargers such as occupancy, charge power, and opening hours available through roaming, you can better serve your EV drivers.
Sara enables hassle-free charging via Plug & Charge and takes care of all the necessary digital certificates that need to be in place. Sara also makes it easy for charge point operators to integrate with other systems such as CRM and invoicing software through open APIs.
Sara connects with any charger running OCPP 2.0.1 and later, facilitating a future-proof and seamless operation. Stations that operate Sara’s counterpart, Josev, enable the smoothest possible operation and can take it one step further by accessing fine-grained analytics and a detailed view on what’s going on in the ISO 15118 communication, between the EV and the charger.
Sara’s AI-powered reporting functionality gives you better insights, such as predictive maintenance and chargers with highest revenue. This allows you to easily manage and analyse any number of charging stations – and strategically develop your operations.
We're currently busy working on Sara, and would love to hear your thoughts as we continue to develop it. Get in touch with the three most interesting features you’d like to see. We listen closely to what our customers and community have to say.
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 Charging Station Management System (CSMS) helps you monitor, maintain, and control your charger network.
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.
