電池標稱電壓 定義如下圖, 以25度為例,20度再往上點, 4V 放一下電就往下掉, 3V 放一下電就往下掉, 假設 3.8V 是擁有最多 capacity 可以 discharge 的電壓,放電放了很久仍維持 3.8V, 因此我們定義 3.8V 為這顆電池的標稱電壓,(不同型號的電池也許不一樣) 通常在電池的外觀可以看到此參數, power consumption 量測 使用假電池測量 power consumption 時, 應該將 電壓 設為 電池的標稱電壓, 因為標稱電壓佔了從滿電到裝置…

Precondition : 配有 power path 功能的 BQ2589 手機. 接上 pc usb port. Origin : 今天有同事問我, 手機是否可以在接上 pc usb port 時,讓手機停充, 有以下幾種停充, 停充_1 : BQ25896 有 power path 的功能, 可以單獨停充電池, 只要 disable CHG_CONFIG bit 即可, 充電器仍可以供給 system. 如圖 停充_2 : 將 charger ic 的 input current 設為…

[Codeforces 1246B] Power Products (STL+分解质因数) 题面 给出一个长度为\(n\)的序列\(a_i\)和常数k,求有多少个数对\((i,j)\)满足\(a_i \times a_j = x^k (x \in \mathbb{N}^+)\).即这两个数乘起来恰好为一个正整数的\(k\)次方 \(a_i,n \leq 10^5\) 分析 考虑\(x^k\)的质因数分解式 , 那么每一项的指数一定是k的倍数,即 \(k|x_i\). 因此对于每个 \(a_i\)…
