Connect：
Alternatively, when parallel control loop is connected on positive pole connecting path of first battery core with the second battery core, terminal
Whether in an ON state equipment first determine whether the first battery core with the positive pole connecting path of the second battery core (such as detection paralleling switch electricity
Whether in an ON state road)；When positive pole connecting path in an ON state when, cut off positive pole connecting path；When positive pole connection
When path is off, then any action is not performed, remain off.
Alternatively, when parallel control loop is connected on negative pole connecting path of first battery core with the second battery core, terminal
Whether in an ON state equipment first determine whether the first battery core with the negative pole connecting path of the second battery core (such as detection paralleling switch electricity
Whether in an ON state road)；When negative pole connecting path in an ON state when, cut off negative pole connecting path；When negative pole connection
When path is off, then any action is not performed, remain off.
Further, when the first connectivity port stops discharging, i.e., when no longer being powered to electricity system, terminal device is then connected
First battery core and the second battery core, to be charged to the first battery core and the second battery core simultaneously.
First battery core and second battery core of S13, connection battery, and the second connectivity port by battery charges to battery.
In this step S13, when the first connectivity port of battery is not discharged, terminal device connects the first of battery first
Battery core and the second battery core, are then charged to the first battery core of battery and the second battery core simultaneously by the second connectivity port of battery.
During specific implementation, terminal device can in the following manner connect first battery core and the second battery core of battery：
Alternatively, when parallel control loop is connected on positive pole connecting path of first battery core with the second battery core, terminal
Equipment first determines whether whether the first battery core is off (such as detection paralleling switch electricity with the positive pole connecting path of the second battery core
Whether road is off)；When positive pole connecting path is off, positive pole connecting path is connected；When positive pole connection
Path in an ON state when, then do not perform any action, remain turned on.
Alternatively, when parallel control loop is connected on negative pole connecting path of first battery core with the second battery core, terminal
Equipment first determines whether whether the first battery core is off (such as detection paralleling switch electricity with the negative pole connecting path of the second battery core
Whether road is off)；When negative pole connecting path is off, negative pole connecting path is connected；When negative pole connection
Path in an ON state when, then do not perform any action, remain turned on.
In the embodiment of the present invention, when the electricity G of whole system is calculated, first end can be measured by voltameter 1 first
The discharge electricity amount g1 of mouth (P1+P1-), the charge capacity g2 of second port (P2+P2-) is measured by voltameter 2, then by public affairs
Formula G=g2-g1 calculates the electricity of whole system.
Further, when the power request of electricity system is received, terminal device can in the following ways start confession
Electric current journey is powered to electricity system：
