技术参数

  电动势

  3HAC031977.2017外电路断开，即没有电流通过电池时在正负极间量得的电位差，叫做电池的电动势。

  端电压

  电路闭合后电池正负极间的电位差叫做电池的电压或端电压。

  电池容量

  3HAC031977.2017通常电源设备的容量用kV·A或kW来表示。然而，作为电源的VRLA电池，选用安时（A·h）表示其容量则更为准确，蓄电池容量定义为∫t0tdt，理论上t可以趋于无穷，但实际上当电池放电低于终止电压后仍继续放电，这可能损坏电池，故t值有限制，电池行业中，以小时（h）表示电池的可持续放电时间，觉的有C24、C20、C10、C8、C3、C1等标称容量值。

  小电池的标称容量以毫安时（mA·h）计，大电池的标称容量则以安时（A·h）、千安时（kA·h）计，电信工业常取C10、C8等标称容量值。例如，常见的Deka电池12AVR100SH为12V单体，100 A·h容量，即可持续放电10h，电流为10A,共放出安时数为10*10=100 A·h（实际测试中，为使电流值保持恒稳，当电压变化时，应调整外电路负载，以便计量）。

  电动车用蓄电池的容量以下列条件表示之：

  电解液比值1．280/20℃

  放电电流5小时的电流

  放电终止电压1．70V/Cell

  放电中的电解液温度30±2℃

  1．放电中电压下降放电中端子电压比放电前之无负载电压（开路电压）低，理由如下：

  1．V=E-I.R

  V：端子电压（V）I：放电电流（A）

  E：开路电压（V）R：内部阻抗（Ω）

  2．放电时，电解液比重下降，电压也降低。

  3．放电时，电池内部阻抗即随之增强，完全充电时若为1倍，则当完全放电时，即会增强2～3倍。

Technical parameter

Electromotive force

3HAC031977.2017 The external circuit is disconnected, that is, the potential difference measured between the positive and negative electrodes when no current passes through the battery, which is called the electromotive force of the battery.

Terminal voltage

The potential difference between the positive and negative electrodes of the battery after the circuit is closed is called the battery voltage or terminal voltage.

Battery capacity

3HAC031977.2017 Usually the capacity of the power supply equipment is expressed in kV·A or kW. However, as A power supply VRLA battery, the choice of ampere-hour (A·h) to indicate its capacity is more accurate, the battery capacity is defined as ∫t0tdt, in theory t can tend to infinity, but in practice when the battery discharge is lower than the termination voltage continues to discharge, which may damage the battery, so the t value is limited, the battery industry, The sustainable discharge time of the battery is expressed in hours (h), with nominal capacity values such as C24, C20, C10, C8, C3, C1, etc.

The nominal capacity of small batteries is measured in milliampere-hours (mA·h), and the nominal capacity of large batteries is measured in ampere-hours (A·h) and kilo-ampere-hours (kA·h), and the telecom industry often takes nominal capacity values such as C10 and C8. For example, the common Deka battery 12AVR100SH is 12V single, 100 A·h capacity, it can be continuously discharged for 10h, the current is 10A, and the total discharge ampere hours is 10*10=100 A·h (In the actual test, in order to keep the current value stable, when the voltage changes, the external circuit load should be adjusted for measurement).

The capacity of the battery for electric vehicles is expressed in the following conditions:

Electrolyte ratio 1.280/20 ℃

Discharge current Current for 5 hours

Discharge termination voltage 1.70 V/Cell

The electrolyte temperature in discharge is 30±2℃

1. The terminal voltage in discharge is lower than the non-load voltage (open circuit voltage) before discharge for the following reasons:

1. V=E-I.R

V: Terminal voltage (V) I: discharge current (A)

E: open circuit voltage (V) R: internal impedance (Ω)

2. When discharging, the specific gravity of the electrolyte decreases and the voltage also decreases.

3. When discharging, the internal impedance of the battery is enhanced, if it is 1 times when fully charged, it will be enhanced by 2 to 3 times when fully discharged.
