Brill Power leverages battery intelligence expertise to bring game changing battery analytics products to market

BrillAnalytics technology now available in three customisable packages; enabling customers to maximise the performance of battery systems through data, insights and AI.

As BESS become larger and profit margins for asset owners face downward pressures, optimising the performance of battery systems is becoming increasingly important. Increasing BESS availability, maximising useable system capacity and fully understanding the true cost of cycling and rate of degradation are becoming key factors in maximising BESS profitability.

BrillAnalytics product range has been developed to address these challenges and more, taking significant data from battery systems to the Cloud and providing meaningful insights to asset owners, developers and OEM’s to continually optimise systems.

BrillAnalytics product range incorporates 3 levels of service: Monitor, Health and performance, each catering to the differing needs of the BESS supply chain. Whilst the insights of BrillAnalytics can be most successfully acted upon when used as part of the Brill Power Battery intelligence Platform, it can equally be used in combination with third party BESS and BMS.


BrillAnalytics Monitor


With BrillAnalytics Monitor, all basis of BESS monitoring are covered and more.

The standard landing page of the dashboard provides an insight into Battery Portfolio performance, reporting on key metrics such as total power, total energy throughput, energy capacity estimates and average SoC as well as summarising the status of each system within a portfolio.

Developed by battery experts, BrillAnalytics is able to calculate State of Charge (SoC) live and online. Unlike many conventional analytics platforms that require to extract the data to analyse it offline, the live data streaming in from the batteries allow calculation in near real-time.

Other crucial information available is real-time notifications to highlight any system errors or potential future issues caused by conditions such as temperatures spreads, SoC imbalance or a module having gone offline – all enabling preventative maintenance to be undertaken and availability increased.

Diving deeper into the dashboard, exploration of individual system, string and module performance informs the user with more granular data including energy, power, ambient and cell temperatures.

BrillAnalytics Health


BrillAnalytics Health delivers a further layer of information vital to the optimised running of a BESS. It is designed to enable battery owners to make more informed decisions on usage patterns and build a strategy based on the health of systems.

System owners and asset managers often struggle to precisely understand the health of systems due to embedded algorithms becoming less and less reflective of actual SoX. Health supports offline computation of SoC and SoH helping to better understand the status of a system and enabling it to reach its full potential.

Health also uses physical and empirical modelling to calculate system degradation rate giving an indication of the reduction in battery performance over time. As the energy storage market matures, it is now crucial to better understand the cost of cycling systems to give way to optimised decision making when bidding in energy markets.

Moreover, the actual degradation rate down to string level can be assessed against warranty criteria provided by the battery manufacturer. If a system or string suffers degradation outside of the warranty specifications, it will show a notification giving an opportunity to secure continuity of protection before it’s too late.

This data also supports the calculation of Remaining Useful Life (RUL) in the batteries which is displayed in BrillAnalytics. This enablies informed augmentation strategies and better planning for future system use.

Notifications in Health alert on imbalance between strings that would stop operators from accessing all energy.  Passive BMS often can’t cope with different voltage and SOC levels across different strings or modules and therefore limit SoC range and require offline calibration through a full charge/discharge cycle. But if the associated BMS is a BrillCore one, Brill Power can conduct continuous balancing on one module while the rest of the system keeps working and retains the same power.

Performance  Coming soon to the BrillAnalytics offer: Performance.

We have identified further needs from integrators and operators and have ensured a smooth communication between what the data tells us and how to use it to adjust the BMS settings to increase system efficiency and performance.

Our proactive BMS optimisation uses battery predictive models so we can simulate lifetime scenarios for an energy storage system and optimise the BMS firmware to maximise available capacity and power as systems age.
