本发明涉及一种镍氢动力蓄电池组智能充电控制方法，是动力蓄电池充电控制方法，属于动力蓄电池技术领域The invention relates to an intelligent charging control method for a nickel-metal hydride power storage battery pack, which is a charging control method for a power storage battery and belongs to the technical field of power storage batteries
背景技术 Background technique
镍氢动力蓄电池具有无污染、高比能、大功率、快速充放电、耐用性等许多优异特性，与铅酸电池相比，具有比能量高、重量轻、体积小、循环寿命长、绿色环保的特点，具有十分广阔的市场需求。Ni-MH power battery has many excellent characteristics such as no pollution, high specific energy, high power, fast charging and discharging, and durability. Compared with lead-acid batteries, it has high specific energy, light weight, small size, long cycle life, and environmental protection. Features, has a very broad market demand.
在影响镍氢动力电池的诸多因素中，充电控制方法是对其寿命和使用性能影响最大的因素，其中对充电过程中的充放电电流、内压和温度的控制尤其重要。目前对镍氢动力电池的基本充电方法主要有恒流充电方法和恒压限流充电方法，以及在此基础上的分级恒流充电方法、脉冲充电方法。其不足之处是：(1)恒流充电方法在充电期间电流保持不变，而电池在其电量较低时充电效率较高、允许高倍率充电，在电池电量较高时充电效率较低、要求小倍率补电，因此恒流充电方法不能适应电池对充电电流的动态要求，容易造成充电时间长，充电效率低，过充发热、内压升高而损坏电池，而且由于充电后期电压升高需要按高功率设计，造成制造成本高；(2)恒压限流充电方法在充电期间电压保持不变，在电池电量低时限制充电电流，在电池电量高时限制充电电压，因此造成电池在其使用前期充电不足、后期容量明显下降。(3)分级恒流充电方法，随着充电进程电流分多级恒流控制，但也仅部分克服了恒流充电方法的不足。(4)脉冲充电方法，首先是用脉冲电流对电池充电，然后让电池停充一段时间，如此循环，该方法利用充电脉冲间的间隙消除或减轻了电池内部的极化与内压，该方法一般用于快充，易导致电池发热，对电池寿命有影响。另外，目前镍氢动力电池充电控制方法都存在以下普遍的不足：缺乏对待充电电池电量的自适应高精度在线估计，尤其是初始电量的估计，而实际上充电过程的起始充电电流及其控制历程都与此紧密相关；充电过程控制参数缺乏与被充电电池状态的实时最优配合，因而不能真正实现最优的充电过程控制。Among the many factors affecting nickel-metal hydride power batteries, the charging control method is the factor that has the greatest impact on its life and performance, among which the control of charging and discharging current, internal pressure and temperature during charging is particularly important. At present, the basic charging methods for nickel-metal hydride power batteries mainly include constant current charging method and constant voltage and current limiting charging method, as well as hierarchical constant current charging method and pulse charging method based on this. Its disadvantages are: (1) The constant current charging method keeps the current constant during the charging period, and the charging efficiency of the battery is high when the battery power is low, allowing high-rate charging, and the charging efficiency is low when the battery power is high. Small rate charging is required, so the constant current charging method cannot adapt to the dynamic requirements of the battery for charging current, which is likely to cause long charging time, low charging efficiency, overcharging heat, internal pressure rise and damage the battery, and because the voltage rises in the later stage of charging It needs to be designed according to high power, resulting in high manufacturing cost; (2) The constant voltage and current limiting charging method keeps the voltage constant during charging, limits the charging current when the battery power is low, and limits the charging voltage when the battery power is high, thus causing the battery to be charged during charging. It is insufficiently charged in the early stage of use, and the capacity drops significantly in the later stage. (3) The graded constant current charging method, along with the charging process, the current is divided into multi-level constant current control, but it only partially overcomes the shortcomings of the constant current charging method. (4) The pulse charging method is first to charge the battery with a pulse current, and then let the battery stop charging for a period of time, so that the cycle is repeated. This method uses the gap between the charging pulses to eliminate or reduce the polarization and internal pressure inside the battery. This method Generally used for fast charging, it is easy to cause the battery to heat up and affect the battery life. In addition, the current Ni-MH power battery charging control methods have the following general deficiencies: the lack of adaptive high-precision online estimation of the battery power to be recharged, especially the estimation of the initial power, and the actual initial charging current and its control during the charging process The process is closely related to this; the control parameters of the charging process lack the real-time optimal coordination with the state of the battery being charged, so the optimal charging process control cannot be truly realized.

The performance degradation of the single battery also means the performance degradation of the battery pack, monitor the battery module voltage, multi-point temperature, etc., perform self-diagnosis on the state of the battery module and calculate the SOC of the battery module online; during the charging process, through the voltage , online measurement of temperature and current and online diagnosis of the battery pack, using the adaptive method of current integration, open circuit voltage calculation, and kalman filter iteration to dynamically calculate the SOC of the battery pack, and monitor the safety status of the battery pack; The rate of rise, temperature, temperature rise rate, SOC of the battery pack, and the online diagnosis result of the battery pack are the inputs of the fuzzy controller. Combined with the online calculated SOC of the battery module charge and the self-diagnosis result of the battery module, fuzzy logic is used. The control method realizes the rapid charging, supplementary charging, and trickle charging current of the battery pack, judges the charging end condition and automatically stops charging, so that the charging efficiency is the highest and the charging time is the shortest. The battery will be damaged due to overheating and high internal pressure, realizing unattended automatic, intelligent, optimal and safe charging control.
本发明与现有镍氢动力蓄电池组充电控制方法相比，具有以下显著效果：采用电池内阻、电压、电流、温度的在线测量，进行电池组在线诊断、荷电量SOC在线计算、电池安全状态监测，并在此基础上采用智能控制方法进行镍氢动力蓄电池充电过程控制，充电过程按预充电、加入负脉冲的脉冲快速充电、补足充电、涓流充电等4个进程依次进行，各进程的充电控制参数、进入使能条件、退出条件等，主要基于高精度的自适应SOC算法、电压及其上升率、温度及其上升率，采用模糊智能方法实时确定，使充电过程实时地与电池状态达到了最佳的配合。因此，本发明提供的方法相对于目前现有方法，大幅度提高了充电效率，缩短了充电时间，同时避免了在充电过程中过热过压而影响电池性能和寿命，实现了无人看守的自动智能化安全充电控制，从而降低了电池使用成本、降低了电池充电的人工成本。Compared with the charging control method of the existing Ni-MH battery pack, the present invention has the following remarkable effects: online measurement of battery internal resistance, voltage, current and temperature is used to perform online diagnosis of the battery pack, online calculation of the SOC of the charging capacity, and battery safety status On this basis, the intelligent control method is used to control the charging process of the Ni-MH power battery.
