The self-locking function of the battery B1 is realized by the resistor R2, the resistor R3 and the MOS tube Q1. Resistor R12, resistor R13, MOS pipe Q11 realize battery B2 auto-lock function. The battery power supply channel is closed by combining a corresponding battery power supply switch, oBON/OFF is an OC/OD signal, and the battery self-locking function can be started and closed through D1 and D11, so that the on-OFF under the condition of battery power supply is realized; oACON/OFF turns OFF the battery power supply switch through the MOS tube Q2 and the MOS tube Q12 when the capacitor CON signal is provided; both B1seleCt and B2seleCt are OC/OD signals, active low, only pulse is needed, and the battery pack is selected through the basic trigger latch circuit.
In the case of mains power (AC), AC ON/OFF is high, turning OFF the battery power path through Q2 and Q12;
In the case of grid power (AC), B ON/OFF, the ON state, i.e., the low state, may be output at all times; it may also be set to an OFF state, i.e. a high resistance state. However, if the AC power supply is in a high-resistance state, once the AC power supply is powered down, B ON/OFF must be immediately turned to a low level, so that a battery channel is opened;
When the power grid (AC) is powered down or removed, the AC ON/OFF state is changed from high to low or high resistance, and the battery power supply path is released through Q2 and Q12;
under the condition of not starting up, the passage filled with the battery is in a self-turn-off state through Q1 and Q11;
If the time problem of long-term storage is considered, the load access pin of the battery pack can be used for complete shutdown, and the battery pack is not in the management system.
The device is started without mains power (AC) and the control signal B ON/OFF of the battery switch is grounded (e.g. a long push button to ground, not shown in the schematic diagram) until the MCU is initialized and the MCU B ON/OFF output is maintained at a low level. B ON/OFF is OC/OD output, and the battery self-locking switches Q1 and Q11 are opened at low level; meanwhile, AC ON/OFF is low level or high resistance, and Q2 and Q12 are both in an open state;
When the battery is started through B ON/OFF, under the condition that two battery packs are in a bin, which battery pack is powered by the battery pack can be selected by combining the default setting of B select, but if only one battery pack is in the bin, the circuit automatically gates the battery pack in the bin, so that the battery pack is flexible and reliable;
In case both battery packs are in the bin, the selection between the two battery packs can be manually achieved by the B1 select and B2 select output by the MCU, and the automatic switching is managed according to the programmed power. B1 Both select and B2 select are active low pulses of OC/OD output, normally high;
Under the condition that only one battery pack exists, the MCU knows the state of the battery pack according to the IN-B identification signal, even if the MCU sends out a B1 select or B2 select switching signal by mistake, if the corresponding battery pack is not IN a bin, the control signal is automatically shielded by the circuit, so that the error conversion is avoided;
When the MCU detects that the electricity of one battery pack is about to run out under the condition that both battery packs are in the bin, the MCU timely switches to the other battery pack through a B1 select signal or a B2 select signal besides giving an alarm; when the electric quantity monitoring is problematic, even if the electric quantity management is not performed, the circuit can automatically cut in another group (R4, R7, R9, R14, R17, R19, Q3 and Q13) when one group of batteries is powered down; in other cases, the MCU monitors the battery voltage besides the electric quantity monitoring (bus) and performs final guarantee. The power supply is ensured not to be interrupted by the control of a hardware and software dual mechanism;
similarly, when two battery packs are in the bin, any battery pack can be plugged and unplugged at will through double control of hardware and software. Even if the battery is unplugged, the other battery can be directly and automatically switched through the circuit.
In example 2, based on example 1, the battery of the present design can be a lithium battery, which has small volume, high stored electricity, long service life and high safety.
