Nivalis’ Modular e-Reefer solution:
Battery System extendable by Photovoltaic & e-Axle.
All use profiles can be covered by the variety of configurations and multiple sources of energy.
Powered Trailer
The Nivalis Powered Trailer represents a new way of thinking about transport electrification. It brings together advanced energy generation, a robust mechanical platform and an intelligent software ecosystem to offer operators a cleaner, more efficient and future‑ready solution.
Its core strength lies in its ability to generate and store clean energy autonomously. Photovoltaic modules and an energy recovering e-Axle feed modular battery packs with a clean and free energy, managed by a smart Energy Management Unit.
There are different options to use this energy:
- power Trailer Refrigeration Unit, making it fully electric, clean and silent (e-Reefer)
- provide Traction Assistance, reducing the load on the towing vehicle and cutting fuel consumption (e-Trailer)
This modular e-System leads to the fast return on investment (ROI) by cutting Operating Expenses, without changing customer’s Business Processes.

Applications
E-Reefer
Battery System stores energy and powers the Refrigeration Unit, enabling fully electric operation. We offer configurations with multiple sources of energy, such as Photovoltaic, e-Axle or charging from the grid.
We consult customers in selection of the battery capacity and right configuration for the desired use profile and operating mode. Right-sized and correctly configured e-System ensures best operation and fast ROI.
E-Trailer
The system maximizes the use of clean Solar and Recuperation energy, store in the Battery System and channel it to the e-Propulsion to assist towing tractor. Thereby we reduce tractor’s diesel consumption or extend its range, if the tractor is electric.
Nevertheless, our e-System can be connected to different auxiliaries of the trailer, such as refrigeration unit or sliding floor to reduce additional generators. Our Software manage the priorities for the energy flow (e.g. refrigeration vs. propulsion).
E-Reefer with E-Truck
Pairing an e‑Reefer with an e‑Truck delivers a fully sustainable solution without affecting truck’s range. Trailer generates its own clean energy, powering Refrigeration Unit independently from the e-Truck without compromising the range and making expensive e‑PTO obsolete.
There are multiple truck-trailer combinations which are best fit for our electrification system. Besides of e-Truck with semi-trailer, drawbar trailer (second trailer behind rigid truck-trailer) is such a case.
Telematics
The telematics system boosts fleet efficiency and reliability by combining predictive maintenance with continuous diagnostics, while tracking energy generation and savings to provide full visibility to fleet owner, operator and driver.
With real‑time and historical data, over‑the‑air updates and seamless integration with fleet management platforms, it creates a smarter, more connected and highly reliable operational ecosystem. Mobile connection and cloud-based data storage, as well as well-organized app dashboard, allow access from everywhere and on any devise.

Platform
The Nivalis electrification kit is a fully modular platform designed to adapt to any trailer configuration, refrigeration unit and most operational profiles. Its architecture is built around scalable battery packs, with optional supplemental energy sources – such as roof‑mounted photovoltaic modules and an e‑Axle – to increase trailer autonomy and enhance overall financial performance.
Every component of the Nivalis Powered Trailer e‑Kit has been engineered and tested to automotive standards, meeting the strictest safety, durability and efficiency requirements. Developed for diverse markets and climatic conditions, these components ensure reliability of the product under demanding temperatures, vibration profiles and harsh environment. In combination, and with smart software solution, the components form a cohesive, seamlessly integrated electrification platform.
Energy Management Unit
Energy Management Unit hosts battery packs – scalable in capacity to match any operational need – and power electronics to manage energy flow within the trailer. It coordinates generation, storage and distribution of energy with precision, directing power to refrigeration, propulsion or other auxiliary loads, while ensuring maximum efficiency and safety. Every electronic and mechanical element of the EMU has been designed from the ground up to meet the specific needs of fleet operators.
As the core intelligence of the Nivalis e‑Kit, the EMU unifies all components into a single, optimised architecture, transforming the trailer into a smart, self‑sufficient and fully electrified system.
PV System
PV system on the trailer’s roof includes solar modules, as well as PV Optimizers for each module. It is significant contribution to the Payback of the system and its autonomy. Thanks to PV and e-Axle, the energy balance – load consumption vs. free power generation – is often positive and makes grid charging a rare activity.
Our flexible solar panels deliver durability, light weight and high efficiency in a fully adaptable format, while Optimizers ensure maximal power generation of each single solar panel.
Our smart installation design and methodology isolate trailer’s roof from heat transfer and simplify cost efficient maintenance of the solar panels.
e-Axle
The primary function of the e‑Axle in the e‑Reefer configuration is to ensure trailer autonomy. The e‑Axle recovers a significant amount of energy through regenerative braking whenever the driver applies the brake pedal or activates the retarder.
Only if there is a risk of insufficient battery charge, e-axle will generate energy without braking activities and secure the cold chain. This functionality provides high level of autonomy and makes it suitable even for long-haul transportation.
Our e‑Motor and gearbox are designed for integration on axle body with motor interface available on the market. With recuperation‑only or recuperation plus propulsion, our e-Motor is an automotive grade product adopted to the harsh trailer environment. The result is the combination of high efficiency (up to 98%) and reliability pared with long product lifecycle.
Charging
The system is designed for CCS1 AC and DC charging. The Battery charging capability is up to 22 kW. If required, DC fast charging can be offered. The battery pack can be charged in parallel with the TRU cool‑down phase.

Charging Connection
The system is designed for AC three‑phase charging via a certified CEE industrial plug (5‑pins). The socket is positioned at the front of the trailer, beneath the TRU. The Battery charging capability is up to 22 kW through the CEE industrial plug. If required, different types of connectors can be assessed, CCS1 for US and CCS2 for EU.
The battery pack can be charged in parallel with the TRU cool‑down phase (powered by the grid).

Value
The Nivalis Powered Trailer delivers a unique value proposition by eliminating diesel consumption and reduction of operating expenses. The fleets become cleaner, smarter and its expenses plannable due to independency from diesel prices. Its modular, right‑sized architecture ensures the best ROI, combining high efficiency with the lowest total cost of ownership. As one of the most sustainable solutions on the market, the system maximises the use of clean, free‑of‑charge energy while guaranteeing non‑stop availability across distribution, long‑haul and hub‑to‑hub operations. With full system control enabled through over‑the‑air telematics, fleets benefit from high availability and measurable financial and environmental impact.
Financial Impact
Depending on customer’s use profile, we achieve industry-leading payback. Additionally, we reduce, or even eliminate, Operating Expenses of the e-Reefer. We make fleet expenses predictable by eliminating dependency from fossil fuel.
The result is: Improved KPI, achieved Gross Profit targets and leveraged Enterprise Value.
We analyse customer’s use profile, calculate savings and configure the right e-System.
Sustainability (ESG)
Immediate and measurable impact on carbon footprint. Our e-kit converts e-Reefer fleets in a silent and environmental-friendly operations from the first mile. Unlike other technologies in transportation industry, introduction of Powered Trailers doesn’t need upgrade of infrastructure or change in operating mode.
Not only will the next generation appreciate the move towards sustainable transportation but also drivers, communities and customers.
Autonomy
Customers who select the optional solar and e-Axle sources of energy, have the liberty to reduce or skip grid charging. PV and recuperation generate often more energy than Reefer can consume. Our system performed well even under extreme climate conditions and long-haul transportation.
