This makes the systems suitable for modern electric drivetrains, heavy-duty power systems, marine propulsion, off-highway machinery, and high-performance commercial vehicle electrification.

Battery capacity can be engineered according to the specific application, vehicle platform, operating profile, available packaging space, and required runtime.

With modular high-voltage battery concepts, different energy capacities can be configured for OEM electrification projects, off-highway machinery, commercial vehicles, and marine battery systems.

Yes.

The modular battery architecture allows KREISEL systems to be adapted to different vehicle sizes, power requirements, voltage levels, and operating profiles.

Both individual battery packs and larger scalable energy storage systems can be implemented for OEM vehicle electrification, industrial machinery, marine vessels, and stationary applications.

KREISEL Electric develops battery systems with high energy density to enable maximum range, long operating times, and efficient use of limited installation space.

The achievable energy density depends on the application, battery configuration, system voltage, safety requirements, cooling concept, and OEM integration strategy.

Safety is a central priority in the development of every KREISEL Electric battery system.

The battery systems include:

• Multi-level safety mechanisms
• Battery Management Systems (BMS)
• Temperature monitoring
• Cell monitoring
• High-voltage safety concepts
• Mechanical protection for demanding applications

Yes.

Every KREISEL battery system is monitored by an intelligent Battery Management System. KREISEL Dynamic Performance Management combines in-house software expertise with proven KREISEL immersion cooling to support safe, reliable, and efficient battery operation.

The BMS monitors and controls:

• Voltage
• Current
• Temperature
• State of charge
• Cell balancing
• Fault conditions and diagnostic events

Yes.

The systems are engineered for demanding duty cycles and, depending on the application, can be used under challenging environmental conditions in off-highway, marine, industrial, and commercial vehicle environments.

These conditions may include:

• Heat
• Cold
• Dust
• Vibration
• Shock loads
• Heavy-duty operating profiles

KREISEL Electric uses a preventive, comprehensive battery safety concept focused on early detection, active thermal management, and intelligent system control.

• Early detection of critical conditions
• Active cell-level temperature monitoring
• Intelligent control through the Battery Management System
• Mechanical protection measures
• Thermal propagation mitigation for high-voltage battery safety

The goal is to minimize the risk of thermal runaway and support safe battery operation in demanding mobile and stationary applications.

Battery lifetime depends on several factors:

The systems are engineered for long-term, reliable operation in demanding duty cycles, helping OEMs reduce downtime and support predictable battery performance over the full lifecycle.

Charging power depends on the specific battery configuration, system voltage, thermal design, charging strategy, and the charging infrastructure used in the application.

KREISEL Electric develops high-voltage battery systems for efficient charging processes, high-power charging capability, short downtimes, and reliable operation in commercial vehicles, off-highway machinery, municipal vehicles, marine applications, and battery-buffered fast charging solutions.

KREISEL Electric relies on an advanced battery thermal management solution. The patented KREISEL immersion cooling system permanently surrounds the individual battery cells with dielectric cooling fluid. This helps maintain an optimal operating temperature for the cells with very low temperature spread, supports consistent high performance, improves battery safety, and contributes to long battery lifetime in demanding high-voltage applications.

KREISEL Electric aims to advance the electrification of industrial applications and help reduce emissions across multiple sectors. By supporting electric drivetrains, battery-powered machinery, commercial vehicle electrification, marine electrification, and battery-buffered charging infrastructure, KREISEL battery systems contribute to cleaner, more efficient, and more sustainable mobility and energy solutions.

Yes.

Lithium-ion batteries can be recycled at the end of their lifecycle. KREISEL Electric considers the requirements of a sustainable circular economy and works with BASF as a sustainability and battery recycling partner. This supports responsible resource management, battery material recovery, and long-term sustainability in industrial electrification projects.

Electric drivetrains reduce local emissions and enable the use of renewable energy in transportation, industrial machinery, marine applications, and stationary energy systems. As a result, high-performance battery systems play an important role in the decarbonization of many industries, especially where diesel-powered machines, commercial vehicles, and marine vessels are being replaced by electric solutions.

In construction equipment, agricultural vehicles, and municipal vehicles, strong vibration and mechanical loads can affect the battery system. KREISEL develops vibration-resistant battery systems specifically for these demanding operating conditions.

Key features:

• Vibration-resistant battery construction
• Mechanically robust cell integration
• Designed for off-highway battery applications
• High reliability in continuous operation
• Proven performance under real-world operating conditions

Thermal management is one of the most important factors for high-voltage battery lifetime. KREISEL uses an active liquid cooling system and patented immersion cooling technology to keep battery cells within an optimal temperature range, reduce cell stress, and support consistent performance in demanding applications.

Benefits of active battery thermal management:

• Reduced cell aging
• Higher charging performance
• Consistently high power output
• Improved battery safety
• Longer battery lifetime and lower total cost of ownership

This helps reduce total operating costs, increase machine availability, and improve the economics of electrified commercial vehicles, off-highway machines, and marine applications.

Yes. Through a network of professional system integrators and long-standing technology partners, KREISEL can provide access to experienced specialists who support existing and new customers with component selection, system design, battery integration, high-voltage architecture, cooling concept development, and electrification projects in off-highway and marine applications.

DNV certification confirms that a battery system has been tested according to demanding requirements for marine applications. For KREISEL batteries, the certification covers aspects such as safety, performance, and environmental suitability. This is especially relevant for marine OEMs because certified battery systems support technical review, risk reduction, project approval, vessel electrification, and shipbuilding integration.

KREISEL offers a DNV-certified high-voltage battery system for marine applications. The system is designed for demanding marine, transport, and off-highway applications and combines robust construction, high safety, compact integration, scalable energy capacity, and reliable thermal management.

When integrating KREISEL battery systems, electrical, mechanical, thermal, and communication interfaces are typically relevant. These include the high-voltage connection, low-voltage power supply, cooling circuit, Battery Management System, communication interfaces, safety logic, charging connection, and vehicle or vessel control system.

Yes. KREISEL describes its marine battery systems as modular and scalable.
