XyloZero Battery Safety
AGV Battery Fire Early Detection
Detects precursor signals before thermal runaway where AGV and AMR batteries charge and wait.
A localization microphone and XyloZero sensor nodes collect sound and condition signals around the batteries. A main control box identifies abnormal events and where they occurred, then alerts the control room and the floor.

Field challenges
Before thermal runaway, a lithium-ion battery can change subtly in sound and ultrasound, not only in temperature. Smoke and flame detectors respond after ignition, so charging areas where many AGVs charge together need a separate check for precursor signals.
How it works
A localization microphone above the charging area listens to the whole zone, and XyloZero nodes mounted near charging stations and battery racks collect condition signals around the batteries. Every device is wired to the main control box for power and data. The control box selects abnormal events at the edge, estimates their location from the sound direction, and sends the result to the control system and on-site alarms.

From detection to response
Sense battery signals
The localization microphone and XyloZero nodes continuously collect sound and condition signals in the charging area.
Select abnormal events
The main control box separates precursor events from normal work sounds at the edge and estimates where they occurred.
Alert the control room
Event type, location and the raw signal go to the control screen and notifications.
Respond on site
On-site alarms and event records help the team check the station and follow up.

Frequently asked questions
- Does it replace existing fire detection?
- No. It complements it, checking signals before smoke or flame appear so the control room and floor teams can respond sooner.
- Where do you start?
- We start with areas where batteries gather, such as AGV and AMR charging areas and battery swap or storage racks. ESS and battery pack storage areas are reviewed with the same configuration.
- How do I get a quote?
- Tell us the size of the area, the number of charging stations, and how far the system should connect to existing control and alarms. We will propose a configuration and quote.
