AI Technical Summary

Technical Problem

Existing handheld electric packing machines are prone to damage to the circuit, rechargeable battery, and equipment when the positive and negative terminals of the charging port are short-circuited, which may even cause safety accidents. There is a lack of effective short-circuit protection devices.

Method used

The short-circuit resistant rechargeable battery design includes a casing, battery pack, protection circuit board, and interface. It utilizes a protection IC, charging MOS, discharging MOS, and short-circuit protection diodes (such as Schottky diodes) to enable circuit conduction or disconnection, preventing damage to the battery and equipment in the event of a short circuit.

Benefits of technology

It effectively prevents damage to rechargeable batteries and devices during short circuits. The protection circuit has a simple and low-cost structure, ensures normal battery charging and discharging functions, and improves safety and reliability.
