−22% temperature rise vs a standard pack.
No pump, no coolant, no moving parts.
Resistance climbs. Heat compounds.
The cell ages fast, and it can run away.
Four concave faces, one for each neighbouring cell.
Hot cells shed their heat straight into the aluminium.
One core per four cells, tiling to any pack size.
The plates drain the heat, and the centre cell touches all four cores.
Your format sets the cut.
Two cells long or ten: the core grows piece by piece.
Four cells bond to each core, along its full length.
Metal plates hold the BATOS® system in place and carry its heat away.
Two identical packs under the same load. The only difference is the BATOS® core.
Internal bench test · two 6S3P packs · 18650 V3 · 25 A discharge · 550 W · 148 Wh · 7.4 Ah · 22 % = lower temperature rise over ~22 °C ambient (peak 51.9 vs 60.1 °C).
Method · thermocouple in the gap between two cells (outer wall) · DC current clamp with dual-temperature logging (PEAKTECH 1670) · standardized CSV protocol · two identical builds, only the core differs.
Backed by published cell data · internal resistance and capacity are temperature-dependent (Panasonic NCR18650B datasheet); cooler operation slows anode-side degradation and extends cycle life (peer-reviewed thermal-management literature).
Cooler cells mean more power, more cycles, and a safer pack.
Power, lifetime, safety: the three curves every pack is judged on all bend the right way.
Pure aluminium: no fluid loop, no moving parts, nothing to maintain. It cools the moment current flows.
Cooler cells keep internal resistance low. That means more usable capacity under load and far slower ageing in every cycle.
Replaces the plastic cell holder, stiffens the pack, and walls cells off to slow thermal runaway.
How BATOS® stacks up against the other ways battery packs are cooled.
Liquid systems remove marginally more heat, but they need pumps, coolant, mass and cost. BATOS® gives you that thermal win passively, plus structure and a thermal-runaway barrier neither alternative offers.
Wherever cells are packed tight and pushed hard, BATOS® drops into the products you already build.
High-current two-wheel packs: the market BATOS® is proven on.
Peak currents from tiny packs, without the heat that ages them.
All the cooling with no pump to carry, where every gram counts.
Large packs that fast-charge without thermal throttling.
Licensing BATOS® secures a real competitive advantage: a measurably better pack that runs cooler, lasts longer and stays repairable.
The measured, repeatable claim your spec sheet gains, and one your engineers can re-run.
A commodity extrusion in place of the plastic cell holder. The BOM barely notices.
Patent protection international (PCT) and national in Germany.
Fully passive: no pumps, no fluids, no operating energy. And the cooling itself makes every cell last longer:
Even heat distribution keeps all cells at a comparable temperature. They age at the same rate instead of drifting apart.
Cooler cells degrade more slowly, so the whole pack stays in service significantly longer.
Individual cells can be replaced instead of scrapping the whole pack. Repair instead of waste.
Cooler, longer-living, repairable: an advantage your customers notice and your competitors would first have to license.
For battery manufacturers. Let's talk integration, volumes and terms.
The license covers the internationally patented, passive BATOS® cooling system. It adapts flexibly to different battery and pack configurations.
BATOS® can be used wherever multiple battery cells are combined into a pack.
Two identical 6S3P packs built from new SONY 18650 V3 cells (2150 mAh), one with BATOS® and one without, discharged at 25 A (≈550 W) over ~16 minutes at ~22 °C ambient, temperature probes logged in the gap between cells. Peaks: 51.9 °C with BATOS® against 60.1 °C without, a 22 % lower temperature rise over ambient. The protocol, instrumentation and raw curves are in the data room, and the test is deliberately simple to reproduce. Step 02 of the licensing path is exactly that: the same measurement with your cells, on your bench, against your own pack.
Almost nothing. That is the design brief: the core takes the slot the plastic cell holder had in your sequence; spot-welding, nickel-strip layout, BMS and housing stay exactly as they are.
The added cost essentially comes down to the difference between aluminium and conventional plastic components.
Yes. Because every cell is held at a comparable temperature, the cells age more evenly.
Each cell sits in its own aluminium cradle, so a failing cell faces a metal wall: a firebreak between neighbours that neither a plastic holder nor glycol tubing provides. Day to day, the same metal breaks the failure spiral before it starts: cooler cells keep internal resistance low, which keeps heat generation low. And mechanically, the core stiffens the whole pack against vibration and impact.
