Description
Technical field
The utility model relates to a kind of charging device, has particularly related to a kind of charging equipment of electric automobile.
Background technology
Along with the propelling of China's energy-saving and emission-reduction policy, the quantity of electric automobile will get more and more.Current electric automobile adopts car load to charge usually and automobile batteries changes the method that electricity fills.Automobile batteries changes electricity and fills, and needs to be equipped with battery and to change the outfit robot, therefore there is the drawbacks such as equipment is many, management difficulty is large, floor space is large.Adopt car load charging to be the many charging modes of current industry, but still there are some problems, because the charging interval is long, a chassis must join a charging device and a charging station, therefore also there is the drawback that charging device quantity is many, floor space is large.The charging device of many charging inlets DC charging device is adopted can greatly to reduce charging device and floor space, but mostly many charging inlets car load charging pile that industry adopts at present is that group technology as shown in Figure 2, just truly now the energy dynamics of charging device is not distributed, just lacked a charging pile, the capacity of rectifying installation is inreal to be reduced.
Summary of the invention
The utility model, for the defect of grouping fixing in prior art, provides a kind of many charging inlets direct-current charging post with energy dynamics regulatory function.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
MOSFET manages, i.e. Metal-Oxide Semiconductor field-effect transistor, comprises G pole (grid), S pole (source electrode) and D pole (drain electrode).Between G pole and S pole, add positive voltage VGS and add positive voltage VDS between D pole and S pole, then produce forward operating current I in D pole and S interpolar.Change voltage VGS and can control operating current I.
Many charging inlets direct-current charging post, comprise monitoring unit, multiple charging module and multiple charging inlet, the output of each charging module is parallel with multiple MOSFET and manages, the MOSFET pipe quantity of the output parallel connection of each charging module is identical with the quantity of charging inlet, each MOSFET manages equal forward and is connected with a diode, the negative pole of diode connects different charging inlets respectively, the G pole connection control plate respectively of all MOSFET pipes, control board plays control action to MOSFET pipe, control board, charging inlet is connected with monitoring unit respectively with charging module, all MOSFET pipes, diode and control board composition energy distributor.Charging module is connected with the D pole of MOSFET pipe in energy distributor, and the S pole of MOSFET pipe connects diode cathode.According to electric current, the voltage parameter of each charging output interface of acquisition of monitoring unit reality, monitoring unit communicates with energy distributor, control board controls corresponding MOSFET pipe and completes switching between the output port of charging module and charging inlet, makes output interface can dynamic assignment power.MOSFET manages latter linked diode and can prevent when cell voltage is higher than charging module, via the backflow of MOSFET pipe generation energy, uncontrollable, damages charging pile.
As preferably, be connected with RS485 communication network between monitoring unit and charging inlet, between monitoring unit and energy distributor, connect by CAN between charging module and monitoring unit.CAN and RS485 communication network highly versatile, and comparatively ripe and reliable.
The utility model is owing to have employed above technical scheme, there is significant technique effect: this charging device is by arranging energy distributor, dynamic multichannel interface energy adjustment can be carried out according to actual conditions, make the high efficiency work of the charging module in device, greatly reduce volume and the cost of equipment, according to the actual conditions dynamic assignment energy of each charging inlet, realize the object of quick charge.
