Proprietary SparkSwitch technology is built into every Sparkion S1 unit to increase overall battery lifetime cycles leading to stronger budget efficiency for owners. The unique SparkSwitch™ technology is mounted to each battery module and allows the SparkCore™ to individually segment module usage regardless of cell health.

Sparkion ESS

The Sparkion ESS is a battery energy storage unit with AI-backed onsite energy management (EMS) that enables seamless optimization of all onsite distributed energy resources (DERs). Our end-to-end solution is custom-designed to address the key challenges facing EV charging site operators today, helping site hosts reduce energy costs, mitigate demand charges and efficiently leverage onsite DERs.

Open-Ended Solution for Seamless Implementation

The ESS can work with any established charger manufacturer and easily integrate with leading EV charging software. Its architecture is designed to reduce site footprint and enable smooth installation and ongoing remote maintenance.

Fully integrated with OCPP
Open API (JSON and Modbus)
Storage performance optimization
Compliant with third parties

Demand Charge AI:


EV charging exposes the site host to potential increased monthly demand charges, sometimes by over 100%. Sparkion’s Demand Charge AI (DCAI) is custom-developed artificial intelligence that learns the usage patterns of your site, then leverages historical and real-time data inputs to optimize how energy is distributed through all onsite DERs.

Demand Response:

Through our integrated partners, we enable full participation in demand response events to support site hosts in maximizing assets and reducing total cost of ownership.

Learning Phase AI:

On day one, machine learning begins to develop a structured methodology. Throughout the first few weeks of usage, it maps your peak onsite kilowatt usage to determine how it impacts your utility bill demand charges.

Financial Reporting:

Automated reporting allows the site host to quantify financial savings from storage integration and provide comprehensive analytics around energy efficiencies.
