In an electric vehicle, the ECU receives input from multiple sensors, including temperature sensors, speed sensors, and current sensors. These sensors provide critical data about the vehicle's state, such as the temperature of the battery pack, the rotational speed of the motor, and the current flowing through the electrical system. The ECU then analyzes this data to make informed decisions about how to adjust the motor output and battery charging. For instance, if the battery temperature rises above a certain threshold, the ECU might reduce the charging rate to prevent overheating and potential damage.

One of the key functionalities of the ECU is to optimize motor output. It does this by adjusting the voltage and current supplied to the electric motor. By fine-tuning these parameters, the ECU can control the motor's speed and torque, ensuring that the vehicle accelerates smoothly and efficiently. During acceleration, the ECU might increase the motor output to provide a powerful response, while during cruising, it may reduce the output to conserve energy. This dynamic adjustment of motor output is crucial for maintaining the vehicle's performance and range.

Battery charging is another critical aspect managed by the ECU. It monitors the battery's state of charge and adjusts the charging rate accordingly. The ECU ensures that the battery is charged optimally, balancing the need for a full charge with the risk of overcharging, which can lead to reduced battery life. Additionally, the ECU might use techniques like pulse charging or trickle charging to maintain the battery at an optimal voltage level, further extending its lifespan.

The ECU's ability to process sensor data and make real-time adjustments is what sets electric vehicles apart from traditional internal combustion engine (ICE) vehicles. This technology enables electric vehicles to offer improved performance, efficiency, and safety. With the ECU constantly monitoring and optimizing the motor output and battery charging, electric vehicles can provide a smooth and responsive driving experience while maximizing the efficiency of their power systems.

Communication: ECU communicates with other ECUs and the central computer

The Engine Control Unit (ECU) in an electric vehicle plays a crucial role in managing and controlling various aspects of the vehicle's performance. One of its primary functions is communication, which is essential for the proper functioning and coordination of different components.

Communication between ECUs is a complex network of data exchange. Each ECU is responsible for monitoring and controlling specific subsystems, such as the motor, battery, transmission, and sensors.
