Batteripak

Batteripak is a modular rechargeable energy storage unit comprising multiple cells grouped into modules and housed in a protective enclosure. Each module contains several cells wired in series and/or parallel to achieve the desired pack voltage and capacity. The pack is typically paired with a battery management system (BMS) that monitors individual cell voltages, temperatures, and state of charge, and that orchestrates charging, discharging, and cell balancing. Thermal management, via air or liquid cooling, helps maintain safe operating temperatures and extend cycle life.

Chemistries commonly used include lithium-ion variants such as lithium nickel manganese cobalt oxide (NMC), lithium iron phosphate (LFP), or nickel manganese cobalt oxide (NCA), as well as emerging solid-state formulations. Battery packs may include protective features such as fuses, circuit breakers, and robust enclosures with ingress protection.

Batteripaks are designed for modularity and scalability, allowing manufacturers to tailor capacity by adding or removing modules. They are deployed in consumer electronics, power tools, e-bikes and electric vehicles, as well as stationary storage for grid-tied or off-grid systems.

Safety standards and testing regimes—such as UL 1642 and IEC 62133 for cells, and UN 38.3 for transport—govern their design and qualification, alongside device-specific requirements.

The term "batteripak" is used in some languages as a direct translation of "battery pack" but in English-language industry the term is often generic rather than brand-specific.
