It is (Liquid Cooling Plate, abbreviation LCP), electrical arrangement unit (Power distribute Unit, abbreviation PDU), straight
Flow converter unit (abbreviation DC/DC), Vehicular charger (On-Board Charger, abbreviation OBC), drive motor controller
(Motor Control Unit, abbreviation MCU), steering motor controller (Steering Motor Control Unit, referred to as
SMCU), braking motor controller (Braking Motor Control Unit, abbreviation BMCU), battery management system
(Battery Control Unit, abbreviation BCU).
The PCU shell is made of top cover, bottom cover, Gaizhonggai, cabinet, and the hole of the fixed connector of cabinet can be split into single electricity
Machine controller can also be split into Double Motor Control device, and PCU may be implemented and be extended to integrated double drive electric machine controller.Its indsole
Lid is welded with bracket and L shape reinforcing rib.
The liquid cooling plate is the material with high thermal conductivity such as aluminum alloy materials or light alloy, by upper cavity under
Cavity is constituted, and upper cavity and lower chamber are machined with radiating ribs and the heat-sinking capability of liquid cooling plate can be improved.
The electrical arrangement unit is made of high voltage connector, preliminary filling resistance, low-voltage relay, high-voltage insurance.It can be with
It is integrated in the top cover for being also desirably integrated into PCU in the bottom cover of PCU.
Its principle is that DC converting unit, Vehicular charger, drive motor controller, attachment electric machine controller is (possible
Including steering motor controller, braking motor controller), IGBT, the components such as stack bus bar it is integrated.It is divided into two by boundary of liquid cooling plate
Layer.There are drive motor controller, Vehicular charger in upper layer；Lower layer is integrated with DC converting unit, attachment electric machine controller, battery
Control unit, electrical arrangement unit, fuse and low-voltage relay circuit board.
The invention has the advantages that
Electrical arrangement unit is integrated into the dimensional space that PCU is greatly reduced in case lid by the present invention, and is more easily safeguarded.
The upper and lower cavities of liquid cooling plate are machined with radiating ribs, keep the heat dissipation performance of PCU stronger, can satisfy double drive motor
The radiating requirements of controller.
The present invention can be arranged to single drive motor controller, can also be arranged to double drive electric machine controller.It is applicable in model
It encloses extensively, cost is easily controllable.
The present invention is relative to other integrated form power control units, and structure size is small, integrated level is higher, assembly is more square
Just, it is easier to mass production.

Specific embodiment.
Referring to attached drawing.
Fig. 1 is Power entry module multiple field power control unit PCU overall diagram built in case lid.PCU is by seal trim strip (1), top
It covers (2), gasket (3), cabinet (4), lower cover (5), liquid cooling plate (13-14) etc. and forms its mechanical structure.By OBC(6), MCU
(7), BMCU(8a), SMCU(8b), DC/DC(9), BCU(10), PDU(11), fuse and low-voltage relay circuit board (12) structure
At its control system.
Case one: referring specifically to Fig. 2, Fig. 3, Fig. 4, Fig. 5.
Fig. 2 is PCU superstructure figure.It can be seen that upper layer is integrated with OBC(6), MCU(7), due to MCU(7) work when
The three-phase current that alternation can be generated can generate interference and OBC(6 to other component) work when MCU(7) it will not work, it in this way can be with
Interference is preferably minimized.It is larger in the electricity of the electric vehicle using dual motors system simultaneously, will not generally integrate OBC(6), at this time
PCU can be extended to collection MCU(7 in pairs).This arrangement degree of flexibility is high.
Fig. 3 is PCU understructure figure.It can be seen that lower layer is integrated with BMCU(8a), SMCU(8b), DC/DC(9), BCU
(10).The BCU(10 used due to different battery producers) it is all different, this arrangement can be compatible with various types of BCU
(10), DCDC(9) Multiple Type can also be compatible with.It can satisfy the different demands of each vehicle factor.
Fig. 4 is PCU bottom cover layout drawing.It can be seen that being integrated with PDU(11 on bottom cover), fuse and low-voltage relay it is integrated
Plate (12).PDU(11) is put on bottom cover can be to greatest extent using the space inside PCU, by the way of interlaced arrangement
Guarantee that the structure size of PCU minimizes.
Fig. 5 is PCU liquid cooling plate.It can be seen that the upper and lower cavities of liquid cooling plate there are radiating ribs, dissipating for liquid cooling plate can be improved
Thermal effect meets the Integrated Solution of double drive motor.
