The three fatal risks of unprotected boards
1. Overcharging explosion crisis: Continuous charging after a fully charged battery can cause the electrolyte to decompose and produce gas. In extreme cases, it may lead to an explosion and fire. Quote the warning of "fire or explosion" from the source.
2. Over-discharge damage is irreversible: Low voltage can damage the electrode structure. The source clearly mentions that "the battery cells will be scrapped rapidly", especially in winter when low temperatures accelerate capacity attenuation.
3. High-load short-circuit risk: In scenarios of sudden acceleration or large current, batteries without protection boards are prone to loss of control due to sudden temperature rise. This can be illustrated by referring to the case of "Short circuit in Electric Vehicles during sudden acceleration" in the reference draft.
Why do manufacturers never omit the protective board?
Analysis of the current industry situation: Even lithium iron phosphate battery manufacturers are 100% equipped with protection boards. The reasons include:
Legal risk: In case of any accident involving unprotected board products, full responsibility shall be borne.
User experience: The source points out that the protection board can extend the lifespan by more than three times, preventing customers from leaving due to premature battery aging.
Technical redundancy: Real-time monitoring by intelligent chips (mentioned in the reference draft) can prevent 99% of abnormal states.
Four iron rules for the scientific use of lithium batteries
1. Refuse to "run naked" : When purchasing, check the label on the protection board and stay away from products without a production date, manufacturer or manufacturer.
2. Regular "check-ups" : Use a multimeter to check the balance of the battery pack to prevent the voltage difference between individual cells from exceeding 0.1V.
3. Environmental control: Avoid use at temperatures below 20℃ or above 50℃ (the source emphasizes the risk of high temperatures).
4. Charging Rules: Use the original charger. Unplug it once fully charged. Do not charge overnight.
Safety is no small matter; protection is the key
Summary of the point: Theoretical feasibility does not equal practical safety. The protection board is the minimum configuration for lithium battery applications. We call on users to abandon the mentality of taking chances, exchange scientific protection for long-term safety, and promote the standardized development of the industry.
