a fifth charging execution module, configured to determine whether the charging voltage of the unit with the lowest percentage of electric power is greater than a preset voltage threshold if the voltage determination is negative, the current determination is positive, and if the electric power determination is positive, determine whether the charging voltage of the unit with the lowest percentage of electric power is greater than a preset voltage threshold, if yes, increase the charging current by the unit with the lowest percentage of electric power, and if not, no longer increase the charging current by each unit;
a sixth charging execution module, configured to, if the voltage is determined as negative, the current is determined as positive, and the electric quantity is determined as negative, each unit does not increase the charging current any more;
a seventh charging execution module, configured to determine whether the charging voltage of the unit with the lowest percentage of electric quantity is greater than a preset voltage threshold if the voltage determination is negative and the current determination is negative, and determine whether the charging voltage of the unit with the lowest percentage of electric quantity is greater than a preset voltage threshold if the electric quantity determination is positive, increase the charging current by the unit with the lowest percentage of electric quantity if the charging voltage of the unit with the lowest percentage of electric quantity is greater than the preset voltage threshold, and not increase the charging current by each unit;
and the eighth charging execution module is used for judging whether the voltage is negative, judging whether the current is negative, judging whether the electric quantity is negative, and preventing the charging current from being increased by each unit.
9. The charging coordination system for a plurality of wireless connection units of claim 7, further comprising: and the canceling module is used for canceling the wireless broadcasting module after all the units enter the constant-voltage charging state.
10. The charging coordination system for multiple wireless connection units of claim 7, wherein said wireless broadcast module is a Bluetooth broadcast module or a WIFI broadcast module.
