 Energy Storage Competitor Landscape  The energy storage market has seen several distinct business models and competitors arise, however, Powin is uniquely positioned to provide the most cost competitive energy storage system                Battery Cell Manufacturing  Battery Pack Assembly  Battery Management System  System Assembly and Integration  Energy Management System  Project Installation  Operation & Monitoring  Business Models in the Energy Storage Value Chain  Integrators  Large Cell Suppliers  Integrated Cell Suppliers  Powin  Powin’s Competitive Advantage  Competitive Business Model  Examples  Powin’s Competitive Advantage  Large Cell Suppliers    Large cell suppliers can deliver battery packs along with a battery management system, however, these packs will need to be assembled on-site by the customer increasing the system cost; Powin delivers fully assembled units decreasing the customer’s installation cost  Integrators    Integrators procure separate system components and assemble them on-site, increasing the time of integration and the cost; Powin’s modular systems can be installed more quickly and with a lower cost  Integrated Cell Suppliers    Tesla is the likely closest competitor to Powin, directly controlling the entire value chainTesla is captive to their own battery cell supply, meaning that if a material in their chemistry rises in value or if a more efficient chemistry is introduced, Tesla’s price will have to go up or their margins will have to go down; Powin is cell agnostic to evolve with the market, keep prices low, and maintain marginsTesla sells equipment to third party developers and while also self-developing projects, whereas Powin purposefully does not compete with customers 

   Description    Why it is Important  Cell Level  Powin has the flexibility to integrate a wide array of lithium based battery cells into the system based on customer demand, end use case, needed parameters, and costThe Powin engineering team can quickly adapt the Powin battery management system to a new cell technology    Flexibility and Low Cost: Based on market dynamics and customer preferences, Powin competitively procures most cost effective cells  Pack Level  The pack consists of roughly 7.8 kWh to 9.8 kWh of cells assembled into an efficient form factorWithin the pack, each cell is connected to a module controller that measures cell voltage and temperature to provide detailed granularity, and discharges the cells for passive balancingEach pack has both a balancing charger and battery pack controller provide active balancing an charging of cells    Lower Degradation: Most pack level designs do not balance to the cell level, causing increased cell degradation; Powin’s pack controller reduces degradation and extends lifeWider SOC Operating Range: Tightly targeted active and passive balancing allows for safely charging higher and discharging more deeplyMore Granular Data: Cell level data from the module controller allows for deeper operational insights  System Level  17 packs form Powin’s ‘Stack140’, the modular, purpose-built 140 kWh battery systemThe modularity of Stack140 eases installation, simplifies maintenance, reduces downtime, and lowers operation costsStack140 can scale easily to multiple MW systems for indoor and outdoor environmentsPowin partners with leading power conversion providers ensure that the system delivered to a customer is turnkey    Full Turnkey Solution: Powin’s fully integrated solution saves customers time and money during installationQuicker Delivery Time: The modular nature of Powin’s technology allows for rapid design and delivery to customers  Software and Control Level  Powin has detailed IP around the Battery Pack Operating System (“bP-OS”) that was designed specifically for stationary storage systems as opposed to EVsThe bp-OS functions unlike most competitors’ battery management systems by evenly synchronizing charge and discharge cycles and provides visibility and predictability into every level of the battery systemPowin’s EMS software manages the entire system    Extends Cell Lives: The balancing manager of bp-OS lowers the degradation of the cells, maintaining higher performance and residual value for the end customersFoundation for Applications: bP-OS acts as a foundation for a suite of current and future value-add applications for customers  Technology Overview  Powin’s IP combined with their thorough approach to engineering and integrating the energy storage system from the bottom up allows them to deliver a low cost, turnkey, and differentiated product to customers    EMS & bp-Os       

   Cell Level  Pack Level  System Level  Software and Control Level  Powin Technology Differentiation    Current Differentiation of Powin’s Patented Applications  Patented applications that run on Powin’s bP-OS provide customers with the ability to strictly enforce battery warranties, optimize operations, and extend a system’s useful life relative to competitors’ BMS  Battery OdometerWhat it is: An application that leverages the bP-OS cell level data, including current factor, voltage factor, and temperature factor, to calculate a cell-level ‘odometer value’, which is a single time-series data set that measures the capacity degradation and remaining life of each cellWhy it is Important: Provides the operator with a real-time, single data set to monitor the performance, optimize operations, and quickly identify issues of the energy storage systemWhy it is Different: Competitors’ systems provide disparate data streams that focus on historical data and do not provide real-time insight to optimize operations    Warranty TrackerWhat it is: An application that closely tracks when a battery storage system is not operating in the warranty parametersWhy it is Important: Battery warranties are crucial to the financeablility of Powin’s systems; the warranty tracker allows an operator to enforce battery warranties with hard data and removes subjectivity and dispute from the warranty claim processWhy it is Different: Battery cell manufacturers do not have an incentive to closely track the warranty to provide flexibility in warranty fulfillment; Powin’s system allows the operator to enforce the warranty with battery OEMs    Balancing ManagerWhat it is: An application that optimizes active and passive balancing to keep a consistent charge across all cellsWhy it is Important: Inconsistent charging causes uneven degradation, harming operations and increasing the degradation of the whole system; Powin’s Balancing Manager reduces cell degradation over the useful life. More granular active and passive balancing allows a wider operating SOC range, make more energy storage available using the same cells, at the same costWhy it is Different: Most competitors’ battery managers were made for EVs and not larger stationary systems and cause uneven degradation of the cells causing shorter useful life of batteries, and making less of the cell capacity available for use    EMS & bp-Os
