NiMH Backup Batteries for Automotive T-Box & Telematics
A vehicle T-Box (telematics control unit) manages GPS tracking, remote diagnostics, emergency eCall and connected-car communication, and it needs a reliable backup power source to finish an emergency call or data transmission if the main vehicle battery is cut. Weijiang Power supplies custom nickel-metal hydride (NiMH) cells and compact packs engineered for T-Box backup power across wide automotive temperature ranges.
Why NiMH for T-Box backup: NiMH offers dependable high-rate pulse output, strong wide-temperature performance and long calendar life in a small, intrinsically safer package than lithium — matching the long service life and reliability expectations of automotive electronics.
- Wide temperature tolerance: cells formulated for cold-crank and hot-cabin conditions, supporting reliable operation across broad temperature swings.
- Compact custom packs: 1.2 V cells assembled into the exact voltage and footprint your T-Box module needs, with tabs, leads, connectors and protection configured to the PCB.
- Stable long-term readiness: low self-discharge options and roughly 500–1000 cycles keep the backup available over years of standby.
- Automotive documentation: CE, RoHS, REACH, MSDS/SDS, UN38.3 and IEC 62133 support, with cells to IEC 61951-2.
Provide your T-Box module's standby duration, pulse current, voltage and space envelope and we will design the matching NiMH backup pack. See our industrial custom NiMH capabilities or request a quote and sample.
Frequently Asked Questions
Q1: What does a T-Box backup battery do?The telematics control unit (T-Box) manages GPS tracking, remote diagnostics, emergency eCall and connected-car communication; the backup battery finishes the emergency call or data transmission if the main vehicle battery is cut.
Q2: Why use NiMH rather than lithium for automotive backup?NiMH provides dependable high-rate pulse output, strong wide-temperature performance and long calendar life in a compact, intrinsically safer package that matches automotive reliability expectations.
Q3: What temperature range can the cells withstand?Cells are formulated for cold-crank and hot-cabin conditions, with wide-temperature and low-temperature lines for demanding automotive environments.
Q4: Can the cells or packs be customized to the T-Box housing?Yes. We engineer compact cells and packs to the available space, with specified tabs, leads, connectors and mounting to fit the telematics unit.
Q5: What qualifications and order terms apply?Custom automotive projects are supported with manufacturing consistency and relevant documentation (CE, RoHS, REACH, IEC 62133 and shipping documents). Requirements are reviewed and quoted within 24 hours.
