[0025] Example one
[0026] There are three groups of battery packs that are connected in series within the group and parallel between the groups. We don't need to consider the internal voltage and power of the battery pack, but only pay attention to the overall voltage of each battery pack. If the voltages of the three battery packs are 2V, 3V and 5V respectively. When in the charging state, due to the parallel mode, the charging pile will charge the 2V battery pack first. When the 2V battery pack is charged to 3V, the two 3V battery packs start to charge together. When they are all charged to 5V, the three sets of 5V battery packs start to charge together until the charge is full. The discharge state is opposite. The same 2V, 3V and 5V battery packs enter the discharge mode. Due to the characteristics of the parallel circuit, the circuit will first discharge the battery pack up to 5V. When the 5V battery pack is placed at 3V, two The 3V battery pack begins to discharge togeth...
