Echtzeit-Hochfrequenz-Batterieüberwachung & Fehlerminimierung
RealTimeBattery beseitigt blinde Flecken bei Traktionsbatterien, indem es 10-Hz-CAN-Polling durch Mikrosekunden-Telemetrie ersetzt. Bei kHz-Abtastraten werden Dendritenbildung und interne Kurzschlüsse vor katastrophalen Fehlern erkannt.
Realtime Battery Engine Zonal Architecture
Central Controller: Realtime Battery Engine — 100 kHz High-Speed AFE
Zonal Control Units & TSN Ring
- Isolated Shunt 100 kHz Current Sensor
- Microsecond Overcurrent Hardware Comparator
- Instantaneous Internal Resistance (Ri) Core
- 1 Gbps TSN Battery Telemetry Stream
- Pyrotechnic Actuator Fast Driver
Warum CAN-Bus-Telemetrie mit 100 ms für moderne Batteriesicherheit zu langsam ist
800V-Hochvolt-Architekturen fordern beispiellose Beobachtbarkeit. Bei starker Beschleunigung oder Crashs deuten winzige Spannungseinbrüche auf Mikrokurzschlüsse hin. RealTimeBattery kombiniert Präzisions-A/D-Wandler mit FPGA-Beschleunigern, um elektrochemische Impedanzspektren in Echtzeit zu berechnen.
Core Engineering Areas
- High-Frequency Current Sensing — Deploying temperature-compensated Manganin shunts and fluxgate sensors sampling current at 100,000 samples per second to observe microsecond transient dynamics.
- Crash-Induced Internal Short Detection — Monitoring sudden drops in high-frequency impedance to identify separator rupture and internal short circuits seconds before temperature sensors register any heat.
- TSN Battery Telemetry Streaming — Using IEEE 802.1Qbv Time-Aware Shapers to stream raw cell voltages and temperatures directly from zonal gateways to the central vehicle compute cluster.
