WHY IT MATTERS

Engineer the battery with the complete eFoil platform

Motor demand, ride profile, package mass, water exposure, thermal paths, connectors, charging, controls, and service procedures must be reviewed together.

ENGINEERING PRIORITIES

What the design must resolve

Propulsion and Ride Profile

Review nominal and peak demand, controller behavior, target run time, reserve, and charging window.

Protection and Control

Coordinate BMS behavior, charger parameters, user indication, and communication needs.

Marine and Mechanical Fit

Develop the enclosure boundary, connectors, cable exits, mounting, and service access.

Manufacturing Readiness

Define controlled materials, assembly, inspections, and agreed end-of-line checks.

SOLUTION ARCHITECTURE

Four connected design layers

Cell and Energy Layer

Chemistry, format, voltage, and capacity remain selected against real project requirements.

Protection and Intelligence Layer

Protection, sensing, state estimation, and communications are coordinated with the platform.

Mechanical and Thermal Layer

Cell support, enclosure, seals, materials, and heat paths form one architecture.

Interface and Production Layer

Power, charge, communication, labels, assembly, and checks are defined together.

FAQ

Common project questions

What information should we provide?

Share motor voltage and current, ride profile, package envelope, environment, charging, interfaces, markets, and forecast.

How is the marine boundary developed?

Joints, seals, connectors, cable exits, materials, service, and storage are reviewed around the actual platform.

How is an architecture selected?

Candidate approaches are compared against propulsion, ride time, space, mass, charging, and environment.

How are prototypes verified?

Acceptance limits and electrical, thermal, mechanical, and environmental methods are agreed for the project.
