Battery & power Cells store energy while management chips monitor temperature, balance charge, and protect the pack. Weight and runtime are closely connected.
Published by Fynca · Research checked September 17, 2026 How we research
How this system works Individual cells connect through busbars, with a management board monitoring the pack.
Connected cells form the pack. Battery-management electronics monitor their voltage, current, and temperature.
Illustrative battery pack & management. Designs differ by manufacturer; the model is not an OEM bill of materials. What to look for: Copper interconnects across cell terminals and thin voltage-sense connections.

Compare the right roles Cells or power electronics? Cells store energy. Battery-management electronics monitor and protect a pack; other power chips convert and regulate voltage. These are complementary businesses with different product economics.
Does a robot battery announcement prove scale? Development, sampling, an individual deployment, and mass production are different stages. The evidence label does not establish significant humanoid revenue or broad battery market share.
LG Energy Solution explicitly markets humanoid batteries. Samsung SDI has a disclosed robot-battery development partnership; TI provides the management electronics.
Open each company below for its source and limitations. Sector membership does not establish a confirmed supply contract.
Inside the assembly Protective pack enclosure The enclosure locates the cells and provides mechanical protection. Pack-level capabilities vary by supplier.
Stock-link scope: LG Energy Solution documents complete robot pack integration. The source does not establish a separate enclosure-manufacturing business.
Lithium-ion cells Cells store energy chemically. Energy density, discharge capability, cycle life, and safety trade against one another.
Stock-link scope: Cell manufacturers with disclosed robot products, applications, development, or deployments. Commercial scale varies substantially.
Cell interconnects Conductive tabs connect cells into a pack. Cell and pack suppliers work with the mechanical and electrical integration.
Stock-link scope: Battery power interconnects are Amphenol’s related role; supply of the illustrated welded cell tabs is not established.
Battery management board Monitoring and protection chips measure cell voltage, temperature, and current, and help balance the cells.
Stock-link scope: Battery-monitoring, protection, balancing, and management electronics. Cell makers and generic motor drivers are listed separately.
Robot power, data & sensor connectors
Humanoid evidence Amphenol explicitly maps humanoid interconnects. It supplies electrical connections, not complete sensors, camera processors, or battery cells.
Am
Amprius Technologies AMPX · NYSE High-energy-density battery technology
Humanoid evidence Amprius markets high-energy cells for humanoid applications. The page does not establish commercial humanoid order volumes.
CAT
CATL 300750.SZ · Shenzhen Robot batteries & pack services
Humanoid evidence CATL identifies its batteries in the Galbot S1 at a CATL factory. A named deployment does not establish broad humanoid battery market share.
EVE
EVE Energy 300014.SZ · Shenzhen High-energy batteries for embodied robotics
Humanoid evidence EVE explicitly discusses battery development for humanoids. Development claims do not demonstrate large-scale shipments.
If
Infineon Technologies IFX.DE · Xetra Motor drivers, power stages & XENSIV sensors
Humanoid evidence The humanoid application portfolio covers power, motor control, and sensing. Hand relevance is control electronics rather than mechanical finger manufacture.
LG
LG Energy Solution 373220.KS · Korea High-density robot battery cells & packs
Humanoid evidence The robot-battery portfolio explicitly includes humanoids and cell/module/pack options. Humanoid revenue is not separately quantified.
MPS
Monolithic Power Systems MPWR · NASDAQ Humanoid power stages & motor electronics
Humanoid evidence MPS documents humanoid SoC power stages and catalogs BMS/motor-control ICs. Supporting power circuitry is not memory manufacturing.
RE
Renesas Electronics 6723.T · Tokyo Humanoid processing, motor control & power
Humanoid evidence Renesas humanoid reference designs cover system compute, servo control, BMS, and dexterous-hand electronics.
ti
Texas Instruments TXN · NASDAQ Battery management & motor-control chips
Humanoid evidence Humanoid reference designs cover motor drives, BMS, sensing, controllers, and multi-axis hand control. TI supplies chips, not complete mechanical hands.
P
Panasonic Holdings 6752.T · Tokyo Lithium-ion cell manufacturing
Robotics products The cell catalogue explicitly lists robotics applications. Cell production does not establish standalone enclosure or busbar manufacture.
SDI
Samsung SDI 006400.KS · Korea High-performance robot batteries
Robotics products The Hyundai/Kia agreement is for service-robot battery development. The release does not specifically establish supply to Atlas or another humanoid.
Industrial motor & power electronics
Adjacent technology ROHM documents industrial motor and power-conversion electronics. The link is component capability, without an identified humanoid customer.
Evidence groupings are not investment ratings. Companies may appear in multiple sectors.
