Circuit diagram of charger with diminishing pulse charging current exponentially
Circuit diagram of charger with diminishing pulse charging current in accordance with index is shown in the above picture. A1 and A2 constitute controlled multi-vibrator. Set the threshold value at around 1.45V. Back electromotive force generated by the polarized electric fields of the battery during charging would directly influence the output state of A2. During the test, when conducting pulse charging to the current, the increasing and decreasing speed of the polarized electric field strength and the depth of electrochemical reaction inside the battery present exponentially changing. The circuit utilizes this discipline to regulate the frequency and pulse brand of the pulse charging current and to realize the goal of controlling.
