    FAQs Regarding Motor Controller for Electric Vehicles

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

      We have designed a 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 Control Solution for Electric Vehicles, 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. 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 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.

      Ans. We have implemented certain diagnostics and fault-handling capabilities in the motor control system ECU.
      Following algorithms for diagnostics are implemented in the application layer:

      • Overload Protection
      • Over-voltage, Over-current protection
      • Fault detection and logging
      • Temperature Monitoring
      Ans. Yes, we do provide support for integration in the production environment for the motor controller ECU.

      We have a team of hardware engineers who can take care of the implementation of the application, HAL and LLD in the vehicle phase.

      We can carry out this activity on-site or support from our premise.

      Ans. The skill set of Engineers who have developed the motor control system is as follows:

      • LLD and HAL implementation skills,
      • ISO 26262 Functional Safety expertise
      • Model Based Development and AUTOSAR expertise
      • FOC algorithm development
      • Bootloader development (Re-usable stack)
      • Hardware development skills w.r.t motor control system
