摘要
针对区域气象观测站的电源系统电池使用寿命较短,更换电池组成本较高的问题,文中设计了基于新型电池的区域自动气象站电源系统。该系统具有模块化的特点,采用基于磷酸铁锂电池与铅酸蓄电池并联的混合动力电池模块,并对电源充放电方式进行了重新设计。在电源系统中针对系统外围设备增加充放电控制模块,包括电池的智能检测电路与充放电的控制电路。该电源系统理论上能够优化电池组放电性能,增加电池组使用寿命。实验结果表明,基于新型电池的电源系统放电性能提高了45%,DOD深度充放电循环寿命增加为原来3.25～7.5倍。该系统具有放电性能好,循环寿命长,成本低廉的特点。
In view of the short service life of the power system battery of the regional meteorological observatory network in Fujian Province,the replacement of the battery has a higher composition. This paper designs a regional automatic weather station power system based on the new battery. The system has modular characteristics,adopts a hybrid power supply module based on lithium iron phosphate battery and lead-acid battery in parallel,and redesigns the power supply and discharge mode,and adds a charge and discharge control module to the system peripheral equipment in the power system. Including the intelligent detection circuit of the battery and the charging and discharging control circuit,the power system can theoretically optimize the discharge performance of the battery pack and increase the service life of the battery pack. The experimental results show that the discharge performance of the power system based on the new battery is improved by 45%,and the deep charge and discharge cycle life of DOD is increased by 3.25-7.5 times. The system has the characteristics of good discharge performance,long cycle life and low cost.
