Pick by function
Each device does one job. Take the ones the system needs, and add another when it needs more.

Battery pack
Edge device — measures & reports
Central controller — decides
Battery connection
Shared network
We at Lithostack™ build off-the-shelf edge devices for battery and high-voltage monitoring.
Each one is plug-and-play:
it joins the same network, measures at the source, and reports to the central controller.
Advantages
Modular by design. Built to scale.
Each device is a server on the shared network: the central controller takes the safety decisions with the whole system in view, and the devices carry them out. They are Safety Elements out of Context, designed to the safety integrity level each function needs under ISO 26262 or IEC 61508, up to ASIL D. Each states the assumptions of use you confirm on integration.
Plug in
Hardware keying gives every device its address on the shared network.
Stack packs
More packs means only more edge devices, all reporting to one controller.
Products
The devices.
A device for each part of the system, all on one shared network.
HV junction box
Pack and link voltage, pack current through an on-board shunt, isolation resistance, and control of four contactors.
In development ↗Cell monitoring
Cell voltages and module temperatures, daisy-chained along the pack.
Concept ↗Current sensing
Pack current across the full operating range, from standby leakage to peak discharge.
Concept ↗Thermal monitoring
Early detection of a thermal event inside the pack, reported to the central controller.
Concept ↗Where it fits
The same part, in any system.
Because a device assumes nothing about what it is fitted to, the same part goes into a vehicle, a grid installation or a data centre unchanged. Put several devices by Lithostack™ on one network and they cover the whole battery system.
- Automotive
- Hybrid and full-electric drivetrains, and the wider transport platforms built on them.
- Grid storage
- Grid-scale and industrial battery energy storage installations.
- Data centres
- Backup and peak-shaving storage in data centre power systems.
