Battery Cold Plates for EV and Energy Storage Systems | ToneCooling

Custom battery cold plates and liquid cooling plates for EV packs and energy storage systems. ToneCooling designs aluminum and copper cold plates for prismatic, pouch and cylindrical cells, including high-temperature desert applications.

Battery Cold Plates for EV and Energy Storage Systems

Electric vehicles (EVs), commercial vehicles and energy storage systems (ESS) require stable and reliable battery temperatures to achieve long cycle life, safety and performance. As power and energy density increase, liquid-cooled battery cold plates have become a key technology in modern battery thermal management.

ToneCooling designs and manufactures custom battery cold plates for EV battery packs, commercial vehicles, stationary storage and backup power systems. We support prismatic, pouch and cylindrical cell formats and can adapt to different pack architectures.

Why Battery Packs Need Liquid Cooling

Battery cells are sensitive to temperature and temperature imbalance. Poor thermal management can cause:

• Reduced capacity and shorter cycle life

• Increased internal resistance and power limitation

• Higher risk of thermal runaway in extreme conditions

Key challenges include:

• High ambient temperatures

  • In some regions, ambient can reach 45–55°C in summer

  • Packs installed in enclosures, vehicles or roadside cabinets

• Uneven heat generation

  • Different cells and modules in a pack may dissipate different amounts of heat

  • Cells in the center may run hotter than cells near the edges

• Long-term reliability targets

  • 8–10+ years of operation for ESS and backup systems

  • Warranty conditions requiring tight temperature control

Liquid-cooled battery cold plates help keep cell temperatures within a narrow and safe band, improving both performance and lifetime.

ToneCooling Battery Cold Plate Solutions

We offer custom cold plate solutions for different battery formats and pack designs:

Prismatic cell cold plates

• Flat or contoured cold plates mounted under or between prismatic cells

• Channels arranged to provide uniform cooling across the entire cell surface

• Suitable for EV packs and stationary battery modules

Pouch cell cold plates

• Plate designs adapted to pouch cell stack arrangements

• Cooling surfaces contacting both sides of the cell stack (if required)

• Options for integrated manifolds to minimize external piping

Cylindrical cell cold plates and baseplates

• Cold plates integrated into modular trays for cylindrical cell assemblies

• Can be combined with aluminum extrusions or cast structures

• Suitable for high-capacity packs and commercial vehicles

We can also discuss hybrid solutions combining cold plates + PCM (phase change materials) for specific applications that require both passive and active thermal control.

Liquid Cooling for ESS and Backup Power Systems

In energy storage and backup power systems, battery packs often operate in harsh or confined environments:

• Roadside cabinets for telecom and smart-city equipment

• Desert or coastal regions with high ambient temperatures

• Indoor or containerized ESS with limited natural airflow

ToneCooling designs battery cold plates that:

• Work with water-glycol loops or dedicated chillers

• Handle elevated ambient conditions and temperature cycling

• Allow easy integration into modular ESS racks or cabinets

We can help you balance thermal performance, cost, and complexity for ESS applications, whether you are working on small backup systems or utility-scale storage.

Design Options and Material Choices

Our battery cold plates are typically built with:

• Aluminum alloys (e.g. 6061-T6)

  • Lightweight and cost-effective

  • Good thermal conductivity and corrosion resistance with proper coolant treatment

• Copper (for special high-performance sections)

  • Used when higher local thermal performance is required

  • Often combined with aluminum structures where appropriate

Internal flow paths can be:

• Serpentine channels

  • Simple, robust and effective for many battery modules

• Multi-channel or microchannel layouts

  • Used when more uniform temperature or higher heat transfer is needed

We design the cold plate according to your requirements on:

• Coolant type (water-glycol ratio, deionized water, etc.)

• Inlet temperature and expected flow rate

• Allowable pressure drop

• Target cell surface temperature and maximum temperature difference

Manufacturing and Quality Control

As a dedicated thermal management manufacturer, we use mature processes to produce reliable battery cold plates:

• CNC machining of channels and interfaces

• Vacuum brazing of complex channel structures and covers

• Friction Stir Welding (FSW) for aluminum plate assemblies

• Surface finishing and corrosion protection where required

Quality and testing options include:

• 100% pressure and leak tests at agreed conditions

• Dimensional checks and flatness control

• Cleanliness measures appropriate for closed coolant loops

For projects with stricter requirements, we can define customized test plans and documentation in the early stage.

How to Start a Battery Cold Plate Project with ToneCooling

To evaluate a battery cold plate solution, you can begin by sharing:

• Battery type and format (prismatic, pouch, cylindrical)

• Module and pack voltage/capacity (e.g. 48V / 400Ah)

• Maximum charge/discharge power and duty cycle

• Ambient conditions (e.g. up to 55°C in desert climates)

• Coolant type, inlet temperature and available flow rate

• Mechanical layout (module arrangement, available space and interfaces)

• Target lifetime and temperature limits (e.g. ≤30°C average cell surface)

Based on this information, we can:

• Propose a suitable cold plate concept and layout

• Provide an initial estimation of thermal performance feasibility

• Issue a quotation for prototypes and mass production

FAQ – Battery Cold Plates for EV and ESS

Q1: Which battery chemistries can your cold plates support?
Our cold plates are chemistry-agnostic. They can be used with various lithium-ion chemistries (LFP, NMC, etc.) and other cell types, as long as the mechanical and thermal requirements are defined.

Q2: Do you only support prismatic cells?
No. We support prismatic, pouch and cylindrical cells. The cold plate design will differ depending on how the cells are arranged in your module or pack.

Q3: What coolant do you recommend for battery cold plates?
Water-glycol mixtures are commonly used due to good thermal performance and freeze protection. The exact ratio and coolant specification should be defined according to your system design.

Q4: Can your cold plates operate in high ambient temperatures, such as 50–55°C?
Yes, we can design cold plates for high ambient conditions, provided that the coolant inlet temperature and flow rate are sufficient. We recommend discussing your exact boundary conditions so we can check feasibility.

Q5: Do you provide thermal simulations?
We can support basic thermal evaluation and cooperate with your in-house or third-party simulation teams. The typical process is to use combined engineering judgment, testing and simulations to refine the design.

Q6: What is the typical lead time for prototypes?
Prototype lead time depends on design complexity and process selection, but we generally aim for a reasonable turnaround after the design is frozen and commercial terms are agreed.
