Immersion Cooled Battery Module
Immersion Cooled Battery Module
Ricardo has developed an immersion cooled battery module for high-performance and safety applications across motorsport, performance automotive, defence, and aerospace sectors. The module is suitable for high charge and discharge rates while meeting the requirements to contain thermal runaway failure events.
Battery modules can be connected in parallel and series in the platform to meet capacity, power, and voltage requirements. The modules are fitted with BMS electronics for cell voltage measurement, temperature measurement, and cell balancing, with isoSPI communication to the Battery Control Unit.
Ricardo’s immersion cooled battery modules are ready to manufacture in low volumes. Modules can be integrated into packs by customers or by Ricardo subject to additional engineering development.
The choice of 21700 cell can be customised. High level specification for baseline module: capacity 724Wh, 42V nominal, 180A peak discharge, 50A peak charge.
Why choose Ricardo's Immersion Cooled Battery
- Ricardo has invested >15,000 engineering hours to design this product for high
performance and safety applications - Baseline product available in short lead times in low volumes
- Customisable for closer match to customer platforms
- Designed for light weight with carbon fibre and glass fibre covers and carrier
- Made in the UK
Our experience
How we supply
The baseline immersion cooled battery module is ready to manufacture to order.
Discharge rates up to 1,000A are possible with different 21700 cells. Ricardo will need to undertake minor engineering modifications to verify performance, manufacturing process, and ensure supply.
Our expert teams can also offer battery pack integration services and manufacture.
Frequently Asked Questions
The immersion cooled battery modules are intended for high-performance applications where weight and high power, in addition to safety, is required. Typical markets are motorsports, hybrid supercars, aerospace, and defence.
We supply to direct to OEMs, tiered suppliers, race teams, prime contractors, and vehicle design authorities. Modules are not available for aftermarket supply.
We can supply in low volumes for platform prototyping or series supply.

Thermal management
Ricardo’s latest innovations in battery cooling and how these advanced battery modules can boost performance for both road and race vehicles.
"Immersion cooling is effective because the dielectric fluid is in direct contact with the individual cells and so dissipates heat from the entire surface area of the cells".
