| *对接设备的技术参数确认 | * Parameter of electrical equipment related to battery |
| 1.用电设备的技术参数 | 1. Electrical equipment data |
| (1)额定输出功率 W(KW) | (1) Nominal output power W(KW) |
| (2)额定输出电压（V） | (2）Nominal output voltage (V) |
| (3)工作时间 t(h) | (3)Working time t(h) |
| 2.为蓄电池浮充电设备的输出技术参数；最高浮充输出电压U(V) | 2.Output data of floating charge equipment of battery maximum output voltage U(V) |
| 3.使用蓄电池的环境温度：T(℃） | 3.Operating ambient temperature: T(℃） |
| 4.其他需要考虑的保险因素：系数K | 4.Other correction factor:K |
| *蓄电池只数的选定 | *Number of cell calculation |
| 1.无浮充电设备维护条件下，以额定电压初选取 : | 1.Non-floating charge condition : |
| 单体电池只数=额定输出电压U(V) / 蓄电池额定电压U（V） | Number of cell required=Floating charge output system voltage / Single cell nominal output voltage |
| 2.有浮充电设备维护条件下，以浮充电压精配选 | 2.Floating charge condition : |
| 单位电池只数=浮充输出电压U(V) / 蓄电池允许浮充电压中间值U（V） | Number of cell required=Floating charge output voltage / Median value of Single cell floating voltage |
| *蓄电池容量选定 | * Battery capacity calculation |
| 蓄电池最低容量计算： | Battery Minimun capacity calculation : |
|
蓄电池最低容量C（Ah） =蓄电池放电电流 I （A）*工作时间 t (h) |
Min Capacity C1(Ah) =Battery discharge current I (A）*Working time (h) |
| =额定输出功率W（KW）/ 1000 / 额定输出电压 U（V）*工作时间 t(h) | =Nominal output power W/ Nominal output voltage U(V)*Working time t(h) |
| 注：如用电设备为分段不同功率工作时，按各分段进行分别计算并累加即可 | Note:If output power falls into different group,total capacity is equal to the sum of each group capacity. |
| *保险系数选定 | *Safety factor |
| 1.放电倍率系数： K1=1/蓄电池特定倍率下放出容量的百分率% | 1.Discharge rate factor :K1=1/DOD% ar specific discharge rate |
| 蓄电池高倍率（大电流）放电时，实际输出容量会低于额定容量，应该考虑放电倍率系数K，修正； | High discharge rate battery,actual output power is less than nominal output power,please reder to discharge rate factor; |
| 2.温度系数修正：K2=1/蓄电池特定温度下放出容量的百分率（%） | 2.Temperature factor :K2=1/DOD% ar specific temperature |
| 蓄电池使用环境温度超过常规要求环境时，应该考虑增加温度系数K修正； | When operation temperature excesses routime temperature required,please refer to temperature factor. |
| 3.老化因素修正：一般在1.20~1.30之间进行选择，常规使用条件下选取1.25为宜。 | 3.Aging factor : K3=(1.2~1.3).under usual condition,please choose 1.25 |
| 蓄电池随着使用次数和时间的增多，均会有一定的老化现象。因此需考虑老化因子系数K修正。 | There is aging occurrence duo to frequent use,please refer to aging factor |
| 4.设计裕度修正：（推荐：常规使用条件下，一般选取1.1为宜） | 4.Design factor:(Recommended: under normal conditions of use, generally select 1.1 is appropriate) |
| 蓄电池制造商考虑到常规使用条件下的各项影响因素，产品也具有一定容量富裕度。但为了确保长期可靠性，选取蓄电池单位也要再自选一定设计裕度保险系数K修正。用户根据实际情况自行选定. | Battery manufacturers take into account the various factors under normal use conditions, the product also has a certain capacity richness. However, in order to ensure long-term reliability, the battery unit must be selected to have a certain design margin insurance factor K correction. Users choose their own according to the actual situation. |
| 注：修正系数的选取，查蓄电池特定条件下的放电曲线进行估算或制造商帮提供。 | Note: The selection of the correction factor, check the discharge curve under the specific conditions of the battery for estimation or manufacturer to provide. |
|
*蓄电池额定容量确定: C=C*倍率系数K*温度系数K*老化因子K*设计裕度K |
*BatteryNominalCapacity: C=C1*K1*K2*K3 |
(备注：本规程供设计部门初选型时参考使用，根据所选蓄电池系列和实际应用状况，与生产商的技术部门进行协商，共同制定适宜的可行方案）
