Intelligent Transportation Batteries: TPMS & ETC Solutions

SUNJ batteries are widely used in the transport and logistics industry. The wide operating temperature range and high pulse performance of SUNJ batteries, excellent low temperature performance and long working life provide effective power support for logistics related applications such as cold chain transportation. In addition, there are ETC, tire pressure monitoring system, geomagnetic induction equipment.

ETC& TPMS battery features

◆ High and Stable Operating Voltage: This ETC battery maintains a stable voltage output, ensuring consistent performance across various applications.

◆ Long Shelf Life: With an annual self-discharge rate of less than 1% at 25°C, these batteries retain their charge for extended periods.

◆ Long Operating Life: Designed for longevity, these TPMS batteries can last through more than 25,000 charge and discharge cycles.

◆ Wide Operating Temperature Range: Capable of functioning across a broad temperature spectrum, making them suitable for diverse environmental conditions.

◆ Stainless Steel Container and End Caps: Adds durability and protection against physical damage.

◆ Non-Flammable Electrolyte: Increases safety by reducing the risk of combustion.

◆ Non-Restricted for Transport: Easy to ship and transport without special restrictions.

◆ High Pulse Discharge Capability: SUNJ's Combined Power Solutions offer high pulse discharge capabilities, ideal for devices requiring sudden power surges.

◆ Large Capacity Retention: These solutions maintain the large capacity characteristic of batteries, providing extended use between charges.

Typical Applications

• ·  Tire Pressure Monitoring Systems (TPMS)

• ·  Electronic Toll Collection (ETC) modules and roadside units

• ·  Cold-chain temperature telemetry & logistics sensors

• ·  Geomagnetic and roadside detection devices

• ·  Asset tracking and remote telemetry for transportation fleets

For devices requiring both instantaneous burst power and long operational life (for example, ETC transmitters or short-range radar triggers), SUNJ offers integrated solutions that pair Li-SOCl₂ cells with high-pulse supporting components (supercapacitors or pulse-rated modules). This hybrid approach preserves cell capacity while delivering the surge currents necessary for reliable transmission.
