Description

A kind of charging device based on matrix form power division

[technical field]

The utility model belongs to charging electric vehicle field, relates to a kind of charging device based on matrix form power division.

[background technology]

Along with the progress of society and the enhancing of environmental consciousness, electric automobile, owing to taking vehicle power as power, can solve fuel-engined vehicle pollution emission environment, problems such as high energy consumption and progressively being favored.And how to charge efficiently to electric automobile be the problem that people pay special attention to, it is related to the universal of electric automobile and promotes.

And along with the continuous increase of electric automobile quantity, demand equal number module being exported to the charge power that varies in size also gets more and more, there is higher requirement to multichannel charging simultaneously.The charging station of prior art adopts man-to-man charging modes usually, an i.e. corresponding parking stall of charging pile, between DC Module and charging parking stall, the method for salary distribution is too single, cause charge power size to be restricted, the vehicle that cannot meet different capacity demand charges at same charging station.

[utility model content]

The purpose of this utility model is to provide a kind of charging device based on matrix form power division, solves existing charging station charge power and distributes single problem.

For achieving the above object, the utility model adopts following technical scheme:

A kind of charging device based on matrix form power division, comprise at least two DC Modules and several power distributing unit, the switching device identical with DC Module quantity is provided with in each power distributing unit, all DC Modules access same power distributing unit respectively by a switching device, the corresponding parking stall of each power distributing unit, power distributing unit exports as charge power supply.

Further, described switching device adopts switch relay, and power distributing unit comprises microcontroller, controls each switch relay open and closure state by microcontroller.

Further, the negative pole of each DC Module accesses each power distributing unit respectively by a switch relay, and the positive pole of each DC Module accesses each power distributing unit respectively by a switch relay.

Further, each DC Module power output is different.

The beneficial effects of the utility model are:

By obtaining actual parking stall required power size, open or close the quantity realizing access DC Module by power distributing unit internal switch, thus control the input size of DC Module power, according to demand power output, the multiple power method of salary distribution can be provided, extending charge power to a great extent distributes interval, the i.e. DC Module of equal number, there is provided more power selection can to charging parking stall, charging modes is flexible, improve charging device utilance, same charge position can give multiple different charge power automobile simultaneously or timesharing charge.

[accompanying drawing explanation]

Fig. 1 is structural representation of the present utility model.

Fig. 2 is theory diagram of the present utility model.

Fig. 3 is PDU control system theory diagram of the present utility model.

[embodiment]

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

As depicted in figs. 1 and 2, from power supply grid input three-phase alternating voltage, enter charging case and be converted into direct voltage, access DC Module group, in DC Module group, multiple DC Module is set, from DC Module group output multi-channel direct current power branch road, accesses multiple PDU control system, namely in power distributing unit, a corresponding parking stall of PDU control system.Wherein, direct-flow positive pole and negative pole separate multichannel respectively, access multiple PDU control system, carry out control open and close state by multiple branch switch device.In this device, DC Module group is minimum is 2 DC Modules, and each DC Module power output is different, and can be the combination of more DC Module, PDU control system PDU is minimum be 2, can be more combination, but consistent with DC Module group quantity.

As shown in Figure 3, described switching device adopts switch relay, and power distributing unit comprises microcontroller, controls each switch relay open and closure state by microcontroller.DC Module group exports direct-flow positive pole and negative pole, is connected in parallel respectively with PDU control system group, has corresponding switch relay to carry out control open and close state respectively.

Below with 3 DC Modules, each DC Module exports as 15kW, and 3 PDU control system are example, are described the implementation of this programme:

As shown in Figure 2, the direct current output negative pole of 3 DC Modules is respectively by switch relay L-1, and L-2, L-3 and PDU-1, PDU-2, PDU-3 connect, and then arrives corresponding parking stall 1, parking stall 2, parking stall 3.

The direct current output cathode of 3 DC Modules is respectively by switch relay S-1, and S-2, S-3 and PDU-1, PDU-2, PDU-3 connect, and then arrives corresponding parking stall 1, parking stall 2, parking stall 3.

The switch relay on off state of direct-flow positive pole must be consistent all the time with the switch relay state of direct current negative pole, citing, requires that L-1 closes simultaneously when S-1 closes, and requires that L-1 disconnects simultaneously when S-1 disconnects.In the following describes, the switch relay S of state all the time with direct-flow positive pole of the switch relay L of all direct current negative poles is consistent, no longer illustrates in description, but in the protection range of this device.

As the switch relay S-1 of PDU-1, with switch relay S-2, close with switch relay S-3, all 6 switch relays of PDU-2 and PDU-3 all disconnect simultaneously, the gross power then outputting to parking stall 1 is 45kW, is namely 45kW to the Vehicular charging power division being parked in parking stall 1.Meanwhile, parking stall 2 and parking stall 3 do not have power stage, and namely charge power is 0.Obviously, the method is applicable to PDU-2 equally separately, PDU-3, and same PDU, and switch relay place-exchange, does not illustrate herein, but in the protection range of this device.

As the switch relay S-1 of PDU-1, switch relay S-2 closes, and 3 switch relays of PDU-2 all disconnect, and the switch relay S-3 of PDU-3 closes.The gross power then outputting to parking stall 1 is 30kW, is namely 30kW to the Vehicular charging power division being parked in parking stall 1.Meanwhile, parking stall 2 does not have power stage, and the while that namely charge power being 0., the charge power on parking stall 3 is 15kW.In obvious the method, can PDU-1 be exchanged, the position of PDU-2, PDU-3, and the position of different switch relay under exchanging same PDU, principle is identical, does not illustrate herein, but in the protection range of this device.

When the switch relay S-1 of PDU-1 closes, S-2, S-3 disconnect, the switch relay S-2 of PDU-2 closes simultaneously, and S-1, S-3 disconnect, the S-3 of PDU-3 closes simultaneously, and S-1, S-2 disconnect, then output to parking stall 1, parking stall 2, the power on parking stall 3 is respectively 15kW, 15kW, 15kW, namely these 3 parking stall charging modes are for all to fill.In obvious the method, corresponding switch can be carried out in the switch relay position of each PDU, and principle is identical, does not illustrate herein, but in the protection range of this device.
