Smart battery tool: SMBus reader for power management

For designers of devices with Li-Ion batteries from Tefoo, there is now an efficient and compact tool available to read out the SMBus data of batteries. This tool provides detailed insights into the status, configuration and measured values of Tefoo hardcase batteries, displayed on a bright two-color display. The displayed information includes:

• Brand, model, serial number, production date
• Battery voltage
• State of Charge (SOC)
• Temperature
• Remaining capacity
• Full Charge Capacity
• State of Health (SOH)
• Number of charge cycles (Cycle Count)

The tool uses a 5-pin blade connector that can be easily plugged into any Tefoo pack. For long-term storage or during sea freight transport, the battery can be put into a deep sleep mode, which reduces its own energy consumption to only 10 μA. The integrated USB-C interface acts as a power supply to wake up the battery after it has entered deep sleep or protection mode.

Tefoo offers a wide range of hardcase Li-Ion batteries, built with Panasonic 18650 cells, which meet the IEC62133-2:2017 and UN38.3 certifications. These certifications enable the fast and safe integration of replaceable Li-Ion batteries into portable and medical devices. Tefoo's battery versions range from 3.6V, 7.2V, 10.8V to 14.4V, with capacities from 3400 mAh to 13,200 mAh.

This tool gives designers instant access to critical battery information and the ability to efficiently optimize power management, contributing to improved performance and safety of devices with Li-Ion batteries.
