Description
技术领域technical field
本实用新型涉及蓄电池监测技术领域，特别是一种蓄电池充放电在线监测系统。The utility model relates to the technical field of storage battery monitoring, in particular to an online monitoring system for charging and discharging of storage batteries.
背景技术Background technique
环境污染和能源危机成为当下发展的两大问题，因此汽车电动化技术以其绿色环保、节能减排等独特优势，得到了广泛的研究。电池作为汽车电动化技术的关键所在，其性能对电动汽车的使用安全以及发展前景具有重大影响。随着电动汽车的种类不同而略有差异。在仅装备蓄电池的纯电动汽车中，蓄电池的作用是汽车驱动系统的唯一动力源。而在装备传统发动机(或燃料电池)与蓄电池的混合动力汽车中，蓄电池既可扮演汽车驱动系统主要动力源的角色，也可充当辅助动力源的角色。可见在低速和启动时，蓄电池扮演的是汽车驱动系统主要动力源的角色;在全负荷加速时，充当的是辅助动力源的角色;在正常行驶或减速、制动时充当的是储存能量的角色。Environmental pollution and energy crisis have become two major problems in current development. Therefore, vehicle electrification technology has been extensively studied due to its unique advantages such as green environmental protection, energy saving and emission reduction. As the key to vehicle electrification technology, battery performance has a major impact on the safety and development prospects of electric vehicles. There are slight differences depending on the type of electric vehicle. In a pure electric vehicle equipped only with a battery, the role of the battery is the only source of power for the vehicle's drive system. In a hybrid vehicle equipped with a traditional engine (or fuel cell) and battery, the battery can not only play the role of the main power source of the vehicle drive system, but also act as an auxiliary power source. It can be seen that at low speed and starting, the battery plays the role of the main power source of the car drive system; when accelerating at full load, it plays the role of an auxiliary power source; Role.
电动汽车的电池以其能量密度高、使用寿命长、绿色环保等优点，在交通运输和工业生产等领域都有广泛应用。然而，电池在充放电循环使用过程中，受温度、自放电率、放电深度、放电倍率等因素的影响，其容量和寿命不断衰减。当电池容量下降为初始容量的70%时，电池的性能将无法满足供电技术要求，必须进行维护或更换，否则会给工业生产带来严重的危害。因此，有必要对电动车电池的剩余寿命进行分析研究，以便最大限度地利用电池的剩余容量，保障企业安全生产。电池具有绿色环保，循环利用年限长、存储产量高、体积重量小等优点，其作为重要的新兴能源之一，已经在工业生产中得到广泛的应用。电池组在循环工作过程中会出现如单体温度过高，电流过大、过放电和过充电等情况，进而导致电池的寿命缩短，甚至引发电池爆炸等安全事故。因此有必要对电动车电池的运行状态进行实时监测和管理，以提高供电系统的可靠性和自动化程度，保障安全生产。Electric vehicle batteries are widely used in transportation and industrial production due to their high energy density, long service life, and environmental protection. However, during the cycle of charge and discharge, the battery is affected by factors such as temperature, self-discharge rate, discharge depth, and discharge rate, and its capacity and life continue to decay. When the battery capacity drops to 70% of the initial capacity, the performance of the battery will not meet the technical requirements of power supply and must be maintained or replaced, otherwise it will bring serious harm to industrial production. Therefore, it is necessary to analyze and study the remaining life of electric vehicle batteries in order to maximize the use of the remaining capacity of the battery and ensure the safe production of enterprises. Batteries have the advantages of environmental protection, long cycle life, high storage output, and small volume and weight. As one of the important emerging energy sources, batteries have been widely used in industrial production. During the cyclic operation of the battery pack, conditions such as high cell temperature, excessive current, over-discharge and over-charge will occur, which will shorten the life of the battery and even cause safety accidents such as battery explosion. Therefore, it is necessary to monitor and manage the operating status of electric vehicle batteries in real time to improve the reliability and automation of the power supply system and ensure safe production.
目前没有专门的蓄电池用于光伏系统中，因此铅酸蓄电池自身的一些缺陷，如耐过充和耐过放能力差，在光伏发电系统中越加明显。由于光伏发电系统随机性强，稳定性差，因此很难保证蓄电池进行规律地充放电。At present, there is no special battery used in photovoltaic systems, so some defects of lead-acid batteries, such as poor resistance to overcharge and overdischarge, are more obvious in photovoltaic power generation systems. Due to the strong randomness and poor stability of the photovoltaic power generation system, it is difficult to ensure that the battery is charged and discharged regularly.
