Изобретение относитс к химическим источникам тока и может быть применено при определении параметров аккумул торов и батарей.The invention relates to chemical current sources and can be applied in determining the parameters of batteries and batteries.
Известны способы измерени внутреннего сопротивлени химического источника тока путем пропускани через испытуемый источник посто нного или переменного тока l.Methods are known for measuring the internal resistance of a chemical current source by passing a constant or alternating current l through the test source.
Недостатком их вл етс низка точность и значительные потери емкости во врем измерени .Their disadvantage is low accuracy and significant loss of capacitance during the measurement.
Известен также способ измерени внутренего сопротивлени химического источника тока путем измерени напр жени на источнике , разр да его на конденсаторную нагрузку , определени напр жени на этой нагрузке и вычислени измер емого параметра 2.There is also known a method for measuring the internal resistance of a chemical current source by measuring the voltage at the source, discharging it to a capacitor load, determining the voltage at that load, and calculating the measured parameter 2.
Однако указанный способ непригоден дл измерени внутренних сопротивлений мощных аккумул торов с низкоомной нагрузкой, так как в цепи разр да аккумул тора присутствует регулировочный реостат, шунт и переход эмиттер - коллектор коммутируютег о триода, не вл ющиес низкоомной нагрузкой .However, this method is unsuitable for measuring the internal resistances of high-capacity batteries with low-impedance load, since an adjusting resistor, shunt and emitter-collector switch commute to the triode, which are not low-impedance, in the battery discharge circuit.
Целью изобретени вл етс повышение точности и улучшение потерь химического источника тэка во врем измерени .The aim of the invention is to improve the accuracy and improve the loss of the chemical source of the TEC during the measurement.
Это достигаетс тем, что в процессе разр да испытуекгого источника на конденсаторн ю нагрузку фиксируют изь енение напр жоки на ней и стро т кривую зависимости того напр жени от времени, выбирают любую точку на участке этой кривой от начала координат до значени напр жени , равного 0, (где ЕХИТ - ЭДС химического источника тока), определ ют координаты этой точки, после чего вычисл ют сопротивлние короткого замыкани химического источника тока на основании уравнени HanpiSжени зар да конденсатора.This is achieved by the fact that in the process of discharging a test source to a capacitor load, they fix the change in voltage on it and build a curve of dependence of that voltage on time, choose any point on the section of this curve from the origin to the voltage value 0 , (where EHIT is the EMF of the chemical current source), the coordinates of this point are determined, and then the short-circuit resistance of the chemical current source is calculated on the basis of the HanpiS equation for the capacitor charge.
На фиг. 1 изображена электрическа схг ма дл измерени сопротивлени короткого замыкани химического источника тока; ка фиг. 2 - крива зависимости напр жени U зар да конденсатора от времени tFIG. 1 shows an electrical circuit for measuring the short-circuit resistance of a chemical current source; ka fig. 2 - curve of voltage dependence of the capacitor charge U on time t
