K32=0, K42=0, K52=0, and it is 0 to have the level signal in each 3rd controlling switch, i.e. K23=0, K23=0, K23=0,
K23=0.
At the same time, always according to fast charge instruction adjustment, (1a supplies Denso to the switch controller 20 with the first power supply unit
Put) corresponding switch module 201, that is, it is 1 to have the level signal in the first controlling switch corresponding with the 1a power supply units, i.e. K11
=1, and the level signal in the second controlling switch is 1, i.e. K12=1, and the level signal K in the 3rd controlling switch13=0.Cause
This, 4 power supply units (2a power supply units, 3a power supply units, the 4a which would sit idle for according to the switch order
Power supply unit, 5a power supply units) and power supply unit (1a) synchronized links corresponding with 1b charging guns to 1b charging guns, with to mesh

As it can be seen that when being powered using Na power supply unit to each charging guns of Nb, if the charging gun in idle state
Quantity and the ratio of quantity of charging gun in seizure condition be not zero, such as, when the ratio is integral multiple D, then believe
Number processor can generate fast charge instruction corresponding with target charging gun, and fast charge instruction is sent to switch controller 20, into
And the switch controller 20 can adjust the closure of corresponding switch module 201 and disconnect attribute, and then can be in occupancy
Each charging gun of state carries out the quick charge of (D+1) again respectively, and at this time, each power supply unit is low power charger, and
Each low power charger can carry out fast charge operation by the way that the DC charging busbar 202 is synchronous to target charging gun, specifically,
Switch controller 20 that above-mentioned table 1 provides is referred to the control situation of internal multiple switch component 201, will not continued to here

Power supply unit, 2a power supply units, 3a power supply units, 4a power supply units, 5a power supply units) pass through corresponding switch module respectively
201 5 charging guns of connection, and the ratio between the quantity of charging gun in idle state and the charging gun in seizure condition
Still it is not zero, i.e., still meets fast charge condition, but the ratio is not integral multiple (for example, when there are 2 idle charging guns and 3 account for
Charging gun) when, at this time, which can receive target charging gun (1b charging guns, 3b charging guns, 5b chargings
Rifle) charging instruction that sends, and can be instructed according to fast charge and control the switch controller 20 (for example 1b fills to part charging gun
Electric rifle and 3b charging gun) 2 speed chargings of progress (speed charging is carried out to 1b charging guns with 1a power supply units and 2a power supply units,
And speed charging is carried out to 3b charging guns with 3a power supply units and 4a power supply units), and in the electric automobile being connected with 1b and 3b
Electricity when being full of, the switch controller 20 can further by 1a power supply units corresponding with 1b charging guns and 3b charging guns and
