Developed by the world’s leading experts on EV charging communication standards, Josev takes care of testing and implementing the latest standards so you can focus on what makes you stand out.
With the latest OCPP and ISO 15118 standards always enabled, your EV charging experience is the easiest, most secure and best
it can be for drivers.
The most convenient and secure way to charge electric vehicles: just plug, and charge. Easy! This seamless charging experience makes RFID and smartphone apps a thing of the past.
Secure communications between the EV, the charging station and the cloud-based management platform. Law-compliant and as safe as online banking transactions.
Allows vehicles to act as power banks on wheels. This 2-way exchange of power supports the electricity grid with renewable energy when needed, and reduces electricity costs for private homes and businesses.
Josev isn’t just for charging electric cars – based on ISO 15118 and the Combined Charging System (CCS), it can also charge motor bikes, cars, trucks, buses, ships and even (small) aeroplanes.
We provide a worldwide, life-time licence for integrating Josev to each charger. There’s also a yearly fee for ongoing updates to Josev.
We offer a communication controller pre-installed with Josev, significantly reducing the cost and time to install. We can also provide Josev embedded into its own communication controller, costs and lead times depend on your needs.
Either way, there’s no extra charge for Switch support. You’ll always have direct access to the world’s leading team of EV charging infrastructure software experts. We take care of ISO 15118 and OCPP compliance and support you for the long term – while you focus on what makes you different.
Enables the most user-friendly and secure charging experience for both AC and DC chargers
Establishes the data link between EV and charger via the charging cable (through PLC via on HomePlug Green PHY)
Establishes the data link between EV and charger via wireless communication (based on IEEE 802.11n)
Second generation ISO 15118, enables vehicle-to-grid, wireless charging, ACD-P , higher data security, and more
Facilitates future-proof features like built-in ISO 15118 support, plug & play installation, powerful remote control & monitoring
The communication between the EV and the charger is usually a black box for CPOs. If the communication fails for some reason, the CPO has usually no insight as to why it happened.
Josev’s ISO 15118 message analyser solves this problem. It logs the ISO 15118 communication between the EV and the charger to enable an in-depth message analysis via a user-friendly cloud-based web interface, including detailed error reporting to enable a more efficient debugging process.

Josev Professional is based on Josev Community, our open source ISO 15118 implementation. We strongly believe in collaboration and sharing knowledge to propel the e-mobility industry forward. Broad collaboration and peer review from our community will always lead to a more durable outcome.
Book your tour →Our over-the-air update technology guarantees your software is always up to date, and your charger always runs on trusted and well-tested firmware, whether it’s new versions of Josev’s own ISO 15118 and OCPP code or third-party apps.
Book your tour →There is also a yearly fee for ongoing updates to Josev. We can provide Josev already embedded onto its own communication controller. Costs and lead times for this are dependent on your production volume requirements.
There is no additional charge for Switch support, which is unlimited. This guarantees your software implementation requirements are fully executed, with direct access to the world’s leading team of charging infrastructure software experts.
You can run Josev alongside your application as a software package tailored to your CPU architecture. In this case, we recommend:
- Linux based system (x86_64, armv7 or armv8 architectures supported)
- 200 MB of RAM
- 100 MB of disk space
We can also run Josev in a Docker container, which is even easier to update and maintain. To run Docker smoothly on your board, we recommend:
- 512 MB of RAM
- 2 GB of disk space
- a CPU with at least 900 MHz clock
Josev Professional is based on Josev Community, our open source ISO 15118 implementation. Our implementation of the new OCPP standards, the MQTT API and its implementation are not part of Josev Community.
We want to accelerate the adoption of ISO 15118 through easier access to this technology, and we want to make interoperability between EV manufacturers and charging station manufacturers as simple as possible. Over the years, we’ve seen newcomers to the market making the same implementation mistakes on ISO 15118 over and over again, which just delays a proper market introduction of ISO 15118. As we don’t deliver our software to car manufacturers (yet), we believe we can have a big positive impact on the industry by providing a reference implementation as a gold standard that the industry will adopt and use to test their own offerings. EV manufacturers all across the globe will then have a proper implementation to test with.
Secondly, Josev will be more valuable for the industry when it is being peer reviewed by other experts. This creates a stronger foundation for everyone.
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.
Our package running Sara AND Josev simultaneously takes your network to the next level.
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.
