FAQs: eCall & T-Box Battery Pack
Can CM Batteries provide both LiFePO4 and Li-ion options for the same application?
Yes. OEMs can select LiFePO4 for thermal stability and safety, or Li-ion for higher energy density and compact design.
Are your battery packs compatible with different telematics and IoT platforms?
Absolutely. Our modular interfaces and IoT-ready design allow easy integration with eCall, T-Box, and connected vehicle systems.
What’s the difference between eCall and T-Box batteries?
eCall: low-power, multi-year standby, focusing on long life, wide temperature range, and safety.T-Box: handles frequent, high-power communication bursts, needing quick pulse response and reliable data transfer.
Why is LiFePO4 battery a preferred choice for eCall systems?
LiFePO4 provides higher safety, better low-temperature performance, and a longer cycle life compared to NiMH or standard Li-ion.
How can long-term maintenance risks be reduced?
Use automotive-grade batteries with long lifespans and low self-discharge. Validate with full cycle and temperature-humidity testing.
