Abstract
1. Способ заряда литий-ионной аккумуляторной батареи из n последовательно соединенных аккумуляторов с подключенными к ним через коммутаторы балансировочными резисторами, заключающийся в контроле напряжения аккумуляторов и отключении заряда по достижению напряжения любого из аккумуляторов заданного максимального значения, отличающийся тем, что при включении заряда выбирают аккумулятор с наименьшим текущим напряжением, а к остальным аккумуляторам подключают балансировочные резисторы на время, индивидуальное для каждого аккумулятора и пропорциональное величине его разбаланса по напряжению относительно выбранного аккумулятора с наименьшим текущим напряжением.2. Способ заряда литий-ионной аккумуляторной батареи по п.1, отличающийся тем, что время подключения балансировочного резистора к каждому аккумулятору ограничивают моментом уравнивания текущей величины его напряжения текущей величине напряжения предварительно выбранного аккумулятора, с наименьшим текущим напряжением, но не более времени включения заряда.3. Способ заряда литий-ионной аккумуляторной батареи по п.1, отличающийся тем, что время Tподключения резистора к каждому аккумулятору рассчитывают исходя из соотношения:Т=(1-U/U)·k·R, гдеU- наименьшее текущее напряжение аккумулятора в аккумуляторной батарее, В;U- напряжение i-того аккумулятора из числа оставшихся, В;k - коэффициент пересчета разницы напряжений аккумуляторов в емкость разбаланса, А·ч/В;R - сопротивление балансировочных резисторов, Ом.1. A method of charging a lithium-ion storage battery from n series-connected batteries with balancing resistors connected to them through switches, which consists in controlling the voltage of the batteries and disconnecting the charge when the voltage of any of the batteries reaches a given maximum value, characterized in that when the charge is turned on, the battery is selected with the lowest current voltage, and balancing resistors are connected to the rest of the batteries for a time that is individual for each battery and proportional to the amount of its voltage imbalance relative to the selected battery with the lowest current voltage. 2. The method of charging a lithium-ion storage battery according to claim 1, characterized in that the time of connecting the balancing resistor to each battery is limited by the moment of equalizing the current value of its voltage to the current voltage value of the preselected battery, with the lowest current voltage, but not more than the charging activation time. ... The method of charging a lithium-ion battery according to claim 1, characterized in that the time T of connecting the resistor to each battery is calculated based on the ratio: T = (1-U / U) k R, where U is the lowest current voltage of the battery in the battery , V; U is the voltage of the i-th battery from the remaining ones, V; k is the conversion factor of the difference in battery voltages into the unbalance capacity, Ah / V; R is the resistance of the balancing resistors, Ohm.
