As shown in Figure 8, in conjunction with reference to figure 1-7, adopt this without dead band induction power taking power-supply system, to carry out power management, comprise the following steps:
POWERUP powers on;
System initialization;
The timer of single-chip microcomputer U produces the time mark of fixed cycle, and mark comes interim, single-chip microcomputer U sampling induction power taking voltage CT_Volt, lithium battery voltage BATT_Volt and load voltage LTC_Volt;
Judge load capacity and the electric quantity of lithium battery of current induction power taking: if load voltage LTC_Volt is higher than lithium battery voltage BATT_Volt and diode current flow pressure drop sum, think that current induction power taking is being load supplying, otherwise think that lithium battery is being load supplying; According to power taking voltage CT_Volt and band thereof, carry situation, judge the load capacity of current induction power taking, set two voltage thresholds, its carrying load ability is divided into A, B, C Three Estate from low to high, and corresponding induction power taking is not enough to drive nominal load, can drives nominal load but deficiency is thought lithium cell charging, can be driven load and can be three kinds of situations of lithium cell charging respectively; According to the current electric quantity of lithium battery of the approximate judgement of lithium battery voltage BATT_Volt, set two voltage thresholds, the over-discharge state that electric quantity of lithium battery is divided into X, Y, the corresponding battery of Z Three Estate: X from low to high, after overdischarge, the lithium battery life-span declines, and should not charge; The corresponding battery nominal situation of Y, chargeable; The situation that the corresponding battery of Z is full of;
The state machine state of single-chip microcomputer U is judged and is shifted: the relation between induction power taking, rechargeable battery and load is combined as to 1,2,3 three states of state by charge switch Charge_switch, induction power taking power switch CT_switch, rechargeable battery powered switch BATT_switch and load switch Load_switch, this state is controlled by state machine output logic, as shown in table 1 below:
