??一電蓄電池充電方法? ?

? 恒流充電法，恒壓充電法，階段充電法。
1，恒流充電法
它是用調整充電裝置輸出電壓或改變與蓄電池串聯(lián)電阻的方法，保持充電電流強度不變的充電方法�？刂品椒ê唵巍�
2，恒壓充電法
充電電源的電壓在全部充電時間里保持恒定的數(shù)值，隨著蓄電池端電壓的逐漸升高，電流逐漸減少。與恒流充電法相比，其充電過程更接近于佳充電曲線。但在充電初期電流過大，對蓄電池壽命造成很大影響，且容易使蓄電池極板彎曲，造成電池報廢。

Charging method of primary battery

Constant current charging method, constant voltage charging method, stage charging method.

1. Constant current charging method

It is a charging method that maintains a constant charging current intensity by adjusting the output voltage of the charging device or changing the series resistance with the battery. The control method is simple.

2. Constant voltage charging method

The voltage of the charging power supply remains constant throughout the entire charging time, and as the battery terminal voltage gradually increases, the current gradually decreases. Compared to the constant current charging method, its charging process is closer to the optimal charging curve. However, excessive current at the initial stage of charging can have a significant impact on the battery life, and can easily bend the battery plate, causing the battery to be scrapped.

3. Stage charging method

This method includes two stage charging method and three stage charging method

① The two-stage method uses a fast charging method that combines constant current and constant voltage. First, charge the battery with constant current to a predetermined voltage value, and then change to constant voltage to complete the remaining charging.

② The three-phase charging method uses constant current charging at the beginning and end of charging, and constant voltage charging in the middle. When the current decays to a predetermined value, it transitions from the second stage to the third stage.

3，階段充電法
此方法包括二階段充電法和三階段充電法
①二階段法采用恒電流和恒電壓相結合的快速充電方法，首先，以恒電流充電至預定的電壓值，然后，改為恒電壓完成剩余的充電。
②三階段充電法在充電開始和結束時采用恒電流充電，中間用恒電壓充電。當電流衰減到預定值時，由 階段轉換到第三階段。
