Description:An Electronic Control System for Electric Vehicle
Field of the Invention
The present invention relates to an electronic control system for electric vehicles. More particularly, this invention relates to an electronic control unit system integrated with battery mounting assembly of the vehicle.
Background of the Invention
In electric vehicles (EVs), the wire harnessing between the Electronic Control Unit (ECU) and the battery plays a critical role in ensuring the seamless operation of the vehicle's electrical systems. One primary issue that engineers and manufacturers face is the complexity of these harnesses due to the high voltage and power demands associated with electric propulsion.
The intricate network of wires must efficiently transmit signals between the ECU and the battery as well as battery to other peripheral components while maintaining safety and reliability. Moreover, factors such as thermal management, electromagnetic interference, and vibration resistance pose significant challenges.
As the EV industry continues to evolve, addressing these wire harnessing issues becomes pivotal in enhancing the overall performance, longevity, and safety of electric vehicles. Robust design, quality materials, and advanced technologies are essential for overcoming these challenges and ensuring the optimal functioning of the electrical systems in electric vehicles.
Typically, in a three-wheeler or any higher version, one would have to make alteration in the existing design of the vehicle so as to ideally place the ECU in the vehicle, which is actually a drawback. In general, separate additional mountings are provided for maintaining a good wire harness and connection with the battery outputs which is another drawback. Further, long length of wires is consumed when ECU and battery power output are situated away from each other, hence loss in power supply to the vehicle.
The arrangements of the ECU relative to other electrical equipment of the vehicle, especially the batteries, create complexity in maintenance or repair of the ECU and because of which it becomes essential to disturb other structure of the vehicle for repairing, removal and maintenance.
It is, therefore, desirable to provide an improved Electronic Control System which overcomes the challenges and drawbacks and obviates complexity associated with the prior arts.

Referring to Figure 2, there is provided a power control system (1) having a cradle type structure (7) within which battery casings (3) are accommodated for allowing battery swapping as and when required. The cradle type structure surrounds the battery casings (3) and mounts electronic control unit (ECU) (2) in its top surface (4) at one of the ends of the cradle type structure along its width. A wire (5) extends from the ECU (2) to a junction box (10) mounted on the back portion of the cradle type structure (7) as well as other peripheral parts for supplying and distributing electrical power and coordinating with various components of the vehicle. The power control system (1) is mounted on the rear portion (6) of the three-wheeler vehicle. The cradle type structure (7) is also referred to as “battery mounting assembly”. The cradle type structure is supported by vibration isolating dampers (12).
Referring to Figure 3, there is shown top view of a side of the power control system (1) wherein the ECU (2) is mounted on the upper portion of the cradle type structure employing plurality of nuts and bolts (8 and 9).
Also, to prove ease of serviceability in terms of accessing ECU connections from rear side of the vehicle, the arrangement of ECU on to the battery mounting assembly also helps to protect ECU from direct exposure to dust and water as it is being placed at higher position and covered and packaged under vehicle body. Further, as the cradle structure is supported on vibration isolation dampers, it protects ECU and attached power supply system from unwanted high vibrations and extends its life.
