This text represents a collaborative effort between Plotly, Ballard Energy Techniques, and Databricks.
Fleets of buses worldwide run on hydrogen gasoline cells made by Ballard Energy Techniques. To steer within the zero-emission power house, Ballard has mixed the ability of Databricks and Plotly Sprint to construct an RDU (Distant Diagnostics Unit) Visualization Platform able to processing greater than 50 terabytes of information and delivering actionable info globally to material consultants, fleet managers and C-level enterprise leaders.
Problem
Going through more and more rising quantities of information, Ballard’s analytics crew encountered efficiency and scalability constraints with legacy structure parts with classical information warehouses and BI reporting, which lowered information viewing and analytics capability to a single week. Moreover, the required stories took weeks to curate and ship, hampering long-term pattern evaluation and up to date strategic selections.
Addressing these challenges by way of commonplace information warehousing and BI options was not viable because of the complexity, scale and granularity of Ballard’s streaming information assortment, pipeline, and analytics necessities. Ballard required an answer to do real-time processing of complicated semi-structured information, carry out ML coaching and inference, and visualize these modifications in a dwell information utility. Together with incoming information not being ordered in time – and fairly considerably so – as required for stream-based processing, together with vital lags in information arrival and lacking chunks of information.
The requirement was for an answer that addressed all these complexities, all whereas being accessible to a various set of inside and exterior stakeholders globally, together with:
- Ballard C-level enterprise management requires a non-technical consumer interface to facilitate complicated evaluation over extra prolonged durations. Executives want to identify long-term and extra vital developments within the area, which requires an immense quantity of information mixed with extremely complicated analytics that information warehouses can’t present in an economical method.
- Ballard material consultants (SMEs) and Buyer technicians who require every day entry to uncooked information (~150 parameters) for particular person models at sub-second frequencies to ship detailed system diagnostics and to construct machine dynamic studying fashions that inform uptime and predictive upkeep methods and actions.
- Buyer fleet managers should evaluation information aggregated from all of their gasoline cell modules (of which there are hundreds in operation presently) to reply essential operational questions equivalent to: What’s the hydrogen consumption per kilowatt-hour generated? Is a selected module working underneath stress and degrading? How does efficiency fluctuate between metropolis vs. freeway driving?
- Bus Integrators should combine gasoline cell modules into the general powertrain of the bus. This future state requires information sharing with exterior prospects, so information governance is essential. Unity Catalog, Delta Sharing and Plotly Sprint Enterprise SSO capabilities are additionally on the roadmap to ship information to our exterior prospects.
RDU Visualization Platform
Now we have a posh, rising information pipeline with presently over 40 billion information factors from our increasing buyer base of gasoline cell modules. We particularly selected the mixture of Databricks and Plotly Sprint as a result of we required a platform able to delivering refined, interactive, at-scale streaming analytics globally – at each a technical and enterprise degree – to a variety of inside and exterior stakeholders in a well timed method.

Ballard’s analytics crew developed the RDU Visualization Platform by integrating Databricks and Plotly Sprint in an Azure cloud atmosphere to ship interactive analytics merchandise for a number of stakeholders, together with the next examples:
- SME Diagnostics App – With minimal curation and by way of dynamic resampling, engineers can choose and filter down into 40 billion uncooked information factors every day, each for guide system diagnostics and to develop predictive machine studying fashions.
Dynamic resampling achieved by way of the Plotly Resampler allows views to be rendered immediately within the browser, even when querying huge time ranges.
Determine 2 – RDU Visualization Platform SME Diagnostics App - High quality Council Efficiency App – This app dramatically lowers limitations to executive-level reporting by offering at-a-glance system-wide operational KPIs with the choice for additional exploratory information evaluation to tell enterprise selections.
Outcomes
- From weeks of lead time to real-time reporting – Ballard’s Government High quality Council now views as much as three years of information in real-time weekly, immediately within the browser — beforehand an not possible scope and cadence. This allows quantifiable long-term visibility into downtime and affect on Ballard guarantee commitments. This unmatched functionality is powered by the combos of Databricks’ unified real-time/batch processing engine utilizing Photon, Structured Streaming, and Delta Dwell Tables. Since these engines could be extremely scalable to ANY information kind, all it takes to get a real-time dashboard is a straightforward plug right into a Plotly Sprint App. To ship this type of efficiency on a cloud information warehouse and dashboarding instrument alone can be prohibitive in value and abysmal efficiency.
- Massively elevated visibility for inside operations groups – With the power to facilitate exploration of as much as 150 attributes from every of hundreds of modules incoming at sub-second intervals, SMEs can visually discover uncooked information at second intervals for any particular person gasoline cell in circulation. This dynamic analytical workflow separates a easy report from an precise information utility that drives strategic information merchandise that prospects use every day. Sprint’s extremely customizable and scaleable pythonic framework can provide the potential of any full-stack internet utility, besides that it may be created at 10x the event velocity, leverage the depth and breadth of the python analytics ecosystem, and help extremely superior information workflows.
- Enhanced selections for exterior prospects – Ballard’s prospects profit from the perception {that a} dependable, granular degree of research supplies on the particular person module/car degree. Prospects can consider their CO2 financial savings in comparison with a standard fleet, monitor hydrogen gasoline effectivity, and analyze bus availability. Presently, this can be a static bi-weekly report, however an internet repeatedly refreshed report primarily based on Databricks Unity Catalog, Delta Sharing and Plotly Enterprise is in growth.
The RDU Visualization Platform continues to evolve, and Ballard welcomes sharing greatest practices with others advancing related targets with these applied sciences. Deliberate enhancements to the Ballard system embody including spatial analytics, point-in-time formal reporting, additional structured streaming optimizations, and different ML growth initiatives.
