电池的放电状态过程

电池放电是将电池内储存的化学能以电能方式释放出来的过程，即电池向外电路输送电流。蓄电池的放电参数主要有放电深度、放电率和连续放电时间。

放电深度是指电池当前的放电状态，用实际放电容量与额定容量的百分比来表示。放电率是指放电时的速率，常用时率或倍率表示。时率是指一定的放电电流放完额定容量所需的小时数，倍率是指规定时间内放出其额定容量时所输出电流的数值与额定值的倍数。

连续放电时间是指蓄电池开始不间断地放电至终止电压时所能进行的时间。放电的方式又分为工况放电、倍率放电、深度放电、恒流放电、恒功率放电。

The discharge state process of the battery

Battery discharge is the process of releasing the chemical energystored in the battery in the form of electrical energy, that is,the battery delivers current to the external circuit. The dischargeparameters of a battery mainly include discharge depth, dischargerate, and continuous discharge time.

Discharge depth refers to the current discharge state of a battery,expressed as a percentage of actual discharge capacity to ratedcapacity. Discharge rate refers to the rate at which dischargeoccurs, commonly expressed as a rate or multiple. Hour rate refersto the number of hours required for a certain discharge current todischarge its rated capacity, and multiplier refers to the multipleof the output current value and rated value when discharging itsrated capacity within a specified time.

Continuous discharge time refers to the time that a battery cancontinue to discharge continuously until the termination voltage.The discharge methods are divided into working condition discharge,rate discharge, deep discharge, constant current discharge, andconstant power discharge.
