AI Technical Summary
Existing battery-powered systems consume battery power too quickly in environments without mains power, failing to meet the needs of long-term use. Frequent battery replacements lead to high maintenance costs and data loss.
The device employs a dual-battery hybrid power supply system, comprising a first battery compartment and a second battery housing, which respectively accommodate non-rechargeable and rechargeable batteries. The power management module controls the battery switching to achieve complementary and uninterrupted power supply.
Extend device battery life, reduce battery replacement frequency, reduce maintenance costs, prevent data loss, and extend the lifespan of the power management motherboard.
