Motor Controller for Electric Vehicles – E-Autos, 2 Wheelers and 3 Wheelers

Ans. Our platform for motor controller for electric vehicle is completely customizable, configurable and ready-to-deploy solution for your Electric Vehicle Applications.

We have designed aQA suite of Base Software, that consist of the Hardware Abstraction Layer (HAL) and Low-Level drivers (LLD). This Base Software can be customized for integration with your Application layer, helping you save substantial development time and cost (approximately 6-8 months).

As an additional value-add, a critical software module of the Application layer, which is Field Oriented Control (FOC) algorithm, has also been implemented and can be readily integrated with your system.

Depending on the project’s requirements, we can also partner for the development of other modules like regenerative braking, speed and torque limiting and so on, for the application layer.

For an organization, that plans to develop a prototype of motor control ECU for electric vehicles, this configurable platform is an ideal solution.

Ans. The design and development of this motor controller for electric vehicle, adheres to the guidelines of the ISO 26262 Standard for Functional Safety in Automotive.

We have a dedicated team of Functional Safety Consultants and Engineers. This team has in-depth knowledge of the ISO 26262 standard and has also delivered successful Consulting and Implementation projects for our Global Automotive Customers.

We will also extend all the necessary support; in order to help you achieved the compliance for the required ASIL value, for your EV project.

Ans. In order to minimize the bench testing and tuning efforts in the FOC algorithm, we tune it using Plant Model simulation.

Here, we simulate the actual operating environment of the Electric Motor and the Motor Controller Solution for FOC algorithm optimization.

Our Model Based Development team has expertise of more than 13 years in the Automotive Domain. They partner with our EV Team to help our customers save time & cost during Bench Testing.

Ans. Our Motor controller solution for Electric Vehicles is built on TI C2000 Delfino family of microcontroller, which is an automotive grade MCU.

In order to help you develop the system on a different microcontroller, we will provide support for the necessary customization of the low-level drivers, of our base software module. The existing Hardware Abstraction Layer designed by our team can be reused completely.

Ans. Our motor controller for electric vehicle is designed to drive different types of motors including BLDC, PMSM, and AC Induction motors.

For all the applications in which these motors are integrated in an Electric Vehicle, our motor control system can be leveraged to demonstrate your PoC.

(Specifications – Our motor controller ECU can drive 2 PMSM motors of 170 Watt and 5kW each, and 1 BLDC motor of 1 kW)

One of the most widely implemented use-case is the Drivetrain of Electric Vehicles (both two-wheelers and cars).

Other auxiliary motor applications can also be built using this platform.

Electronic Power Steering is another use case of our motor controller driven BLDC motor. It may not be specific to Electric Two-Wheelers, but every electric car/truck (four-wheeler or higher) will need power-steering.
