EV Battery Cold Plates for Australia
ToneCooling Australia supplies aluminium liquid cold plates for EV battery packs, inverters and on-board chargers, joined by controlled-atmosphere brazing (CAB) and friction stir welding (FSW) — the same processes used in Tier-1 automotive supply. Prismatic, pouch and cylindrical formats; 50/50 EGW; PPAP 1–5 on request. Manufacturing at our IATF 16949-aligned facility in Huizhou, Guangdong, China; engineering support from Carlton, Victoria.

ToneCooling Australia manufactures EV battery liquid cold plates — aluminium, CAB and FSW joining, for prismatic/pouch/cylindrical packs, inverters and OBCs, with PPAP 1–5 qualification. Manufacturing is in Huizhou, Guangdong, China; support from Carlton, Victoria.

EV vs grid energy storage cooling
For grid-scale battery energy storage (BESS) cold plates and AS/NZS 5139 design, see our BESS cold plate and BESS solution pages. EV (vehicle) battery cold plates share the aluminium CAB/FSW platform but add automotive weight, vibration and qualification requirements.
Frequently asked questions
Do you make EV battery cold plates for Australian programmes?
Yes. ToneCooling supplies aluminium liquid cold plates for EV battery packs, inverters and on-board chargers, joined by controlled-atmosphere brazing (CAB) and friction stir welding (FSW) — the same Tier-1 automotive processes. Manufacturing in Huizhou, China; PPAP and engineering support coordinated from Carlton, Victoria.
What cell formats and coolant are supported?
Prismatic, pouch and cylindrical formats with custom plate dimensions and flow-channel layouts; tested with 50/50 ethylene-glycol water (EGW).
What joining and qualification do you provide?
Controlled-atmosphere brazing (CAB) and friction stir welding (FSW); PPAP Level 1–5 documentation for automotive OEM qualification on request; 100 % leak testing.
How does EV battery cooling differ from grid BESS?
EV (vehicle) battery cold plates prioritise weight, vibration and automotive qualification; grid BESS plates (see our BESS pages) prioritise large-format module cooling and AS/NZS 5139. Both use aluminium CAB/FSW construction.
