  "textContent": "This invention extends battery lifetime by reducing ambient temperature through these steps: adjusting ambient temperature, conducting degradation tests to obtain SOH degradation curves under various temperatures; analyzing the real-time and long-term effects of temperature drops on SOH loss and lifetime gain; balancing negative SOH impacts and positive lifetime gains to calculate the optimal ambient temperature; dynamically regulating ambient temperature to keep battery temperature within ±2° C. of optimal. Selecting this optimal temperature doubles the battery's total cumulative lifetime without seriously affecting single-charge performance, significantly reducing replacement and maintenance costs.",
