What p&e power&energy GmbH does

p&e power&energy GmbH is a privately held German power-electronics company founded in 2018 and headquartered in Kassel (Universitätsplatz 12, 34127). It is incorporated as a GmbH (HRB 17741, Amtsgericht Kassel) under Managing Director Gerold Schulze, with no external institutional investor, parent entity, or subsidiaries identified in the source data. The company has an employee headcount in the 11-50 range (number unspecified) and reports only one operating geography (Germany) in the source, despite a stated global licensing ambition.

The company's product is a modular power-electronics platform built on a multi-level converter with cascaded H-bridge (CHB) architecture integrated at the individual battery-cell level. Each cell stage has four switching states (Open, Bypass, Positive, Negative), enabling per-cell charging and discharging control, active bypass of weak or defective cells, and claimed converter/inverter efficiency above 98% using LV-Si-MOSFETs. The platform is software-defined across voltage type, voltage range, frequency range, current range, and cell chemistry, and currently scales to 1500 V DC and 200 A AC/DC/Any-C (Demonstrator 480s). A companion User Interface / Cell Monitoring Dashboard provides real-time state-of-charge, temperature, and remote diagnostics. The company has validated performance through a 132s LFP BESS endurance test and three peer-reviewed IEEE publications (EPE'22, PESS/PELSS 2022, ECCE Europe 2024).

The business model is enterprise-direct licensing in three steps (initial consultation, concept analysis, provisioning of hardware components, PCB assemblies, documentation, and software under personalized license), complemented by hardware sales and professional services. Pricing is quote-based and not publicly disclosed. Target segments are split horizontally between stationary storage (renewables integration, sector coupling, UPS backup, fast-charging, grid support) and mobile storage (ships, commercial vehicles, cars). Revenue is supplemented — not replaced — by non-dilutive federal R&D grants from BMBF, BMWK, and ZIM, and by research collaborations with Universität Kassel, Leibniz University Hannover (L3S), MCIB (maritime), and V3C. Awards include the 2024 DKE Startup Award, the Climate Prize of the City of Kassel (2025), Hessen Champions 2025, and a The Smarter E Award 2025 finalist placement.

Core offering

p&e power&energy GmbH develops and licenses a cell-level power electronics platform based on multi-level converter technology with cascaded H-bridge architecture, integrated directly at individual battery cells. The platform consolidates power electronics and battery management into a single system, enabling intelligent per-cell charging/discharging, software-defined voltage/frequency/current/cell-chemistry configuration, and scalability up to 1500 V and 200 A. The company delivers hardware components, PCB assemblies, documentation, and software to enterprise customers under personalized license agreements, supported by consultation, concept analysis, and integration assistance.

Product overview

p&e power&energy GmbH offers a modular power electronics platform based on multilevel converter technology with cascaded H-bridge architecture at the battery cell level. The core platform integrates into a single system what were previously separate components—power electronics at cell level combined with battery management—delivering up to 20% lower costs, 50% longer lifetime, and 90% reduced energy losses. The platform is software-defined, supporting configurable voltage type, voltage range, frequency range, current range, and cell chemistry. A companion User Interface / Cell Monitoring Dashboard enables real-time SOC and temperature monitoring with remote access. The company also provides licensing services and hardware components (PCB assemblies, documentation, software) for seamless implementation.

Broad incumbents

• Sungrow: Sungrow is one of the world's largest suppliers of PV inverters and energy storage PCS, including DC/DC converters and battery interfaces. Directly overlaps with p&e's downstream application (BESS power conversion) but sells at system level across thousands of MW of deployed capacity.
• SMA Solar Technology: SMA is a leading German incumbent in photovoltaic and battery inverters/PCS for residential, commercial, and utility-scale storage. Overlaps with p&e in PCS for stationary storage but operates at much broader scale with full product portfolios, not focused on cell-level architecture.
• Schneider Electric: Schneider Electric offers power conversion systems, BESS integration, and energy management software across commercial, industrial, and utility segments. Overlaps with p&e's stationary storage use cases (renewables, UPS, EV charging) and competes for the same integrators and developers.
• ABB: ABB is a broad industrial and power-electronics incumbent offering PCS, inverters, and energy storage integration solutions via its Electrification business. Comparable because it builds utility-grade power conversion hardware and competes for the same BESS and grid-flexibility tenders p&e targets.
• Siemens Energy: Siemens Energy provides grid-scale PCS, storage solutions, and power electronics under its Transmission & Distribution portfolio. Comparable as a large established supplier into the same utility-scale storage and grid-support applications that p&e's CHB platform addresses.

Emerging players

• Stem Inc: Stem Inc offers AI-driven energy storage optimization and EMS controls for commercial and utility-scale storage. Comparable to the software-defined / EMS portion of p&e's value proposition, although Stem optimizes at system level rather than cell level.
• Corvus Energy: Corvus Energy specializes in battery energy storage systems for maritime vessels, including cell-level battery monitoring and power management. Highly comparable in the maritime use case where p&e executed its MCIB project, though focused on shipyard integration rather than core power-electronics IP.

Others

• TWAICE: TWAICE provides battery analytics software (state-of-health, lifetime forecasting) for BESS and EV customers. Comparable to p&e's monitoring dashboard and cell-level SOC/temperature features; both add a software-defined value layer on top of battery hardware.
• Infineon Technologies: Infineon supplies power semiconductors (including LV MOSFETs and Si/SiC devices) used in PCS and inverters. Comparable as a key component enabler of the multi-level converter topology p&e builds upon, and an adjacent ecosystem player rather than a direct competitor.

Direct peers

• Brill Power: Brill Power develops intelligent cell-level power electronics and battery management for stationary and marine energy storage, using similar approaches to p&e (modular power conversion integrated at the cell level with bypass capability). Closest direct competitor on cell-level intelligent power electronics architecture.
