Изобретение относитс к области электротехники , в частности к способам определени остаточной емкости свинцовых аккумул торов.The invention relates to the field of electrical engineering, in particular, to methods for determining the residual capacity of lead-acid batteries.
Известен способ определени остаточной емкости аккумул тора, например свинцового, путем зар да его измен ющимс по величине посто нным током фиксировани величины этого тока при заранее установленных услови х и определени искомой величины по экспериментальной кривой.A known method for determining the residual capacity of a battery, for example, a lead one, by charging it with varying direct current, fixes the magnitude of this current under predetermined conditions and determines the desired value from an experimental curve.
По предлагаемому способу с целью повышени точности измерени зар д осуществл ют увеличивающимс током до момента начала газовыделени , определ ют величину тока в этот момент и по кривой зависимости остаточной емкости от плотности зар дного тока определ ют искомую величину.In the proposed method, in order to increase the accuracy of the measurement, the charge is made by increasing current until the start of gas release, the current value is determined at this moment, and the desired value is determined from the dependence of the residual capacity on the charge current density.
Дл осуществлени предложенного способа аккумул тор подключают к устройству, позвол ющему плавно увеличивать величину зар дного тока. Зар дный ток плавно увеличивают до величины, при которой начинают выдел тьс пузырьки газа, и фиксируют ее. Полученное значение тока дел т на площадь поверхности положительных пластин, т. е. вычисл ют плотность тока.In order to implement the proposed method, the battery is connected to the device, which allows to smoothly increase the magnitude of the charging current. The charging current is gradually increased to the value at which gas bubbles begin to emit, and it is fixed. The resulting current value is divided by the surface area of the positive plates, i.e., the current density is calculated.
По графику зависимости величины остаточной емкости от плотности зар дного тока, при которой начинаетс газовыделение, полученному экспериментально или по аналитической зависимости, описывающей этот график, определ ют остаточную емкость аккумул тора.The residual capacity of the battery is determined from the graph of the residual capacitance versus the charge current density at which gas evolution begins, obtained experimentally or from an analytical relationship describing this graph.
