Working Modes Transition
This design has 3 working modes: normal mode, standby mode, and ship mode. When the pack is charging or
discharging, it is in normal mode. Sleep mode is when no charging nor discharging, the pack is waiting for
charger or load attachment. Shutdown mode is a very low current consumption mode which saves energy and
helps to avoid battery over discharge when the pack or cell voltage is low. Different working mode transition are
shown in Figure 3-11 to Figure 3-14.
