The analysis of electrical car motors is predicated on many elements. Primarily, it’s primarily based on three factors- sturdiness, efficiency, and reliability of an electrical car motor.
The analysis system for the evaluation of an electrical car’s motor simulates the real-world driving situations. It measures and information very important parameters similar to velocity, torque, energy, and temperature.
Thereafter, the information collected by the analysis system is used to establish key areas of enchancment within the efficiency of an electrical car’s motor.
The important thing parameters on which an electrical car’s motor is evaluated are as follows:
First, fixed load testing. On this testing methodology, a set load is utilized to an electrical car’s motor for a continuing time interval. This load may be set to a predetermined worth. After which, it information the motor’s efficiency when it comes to its temperature, torque, velocity, and energy consumption.
Second, real-time DC- An actual-time DC is constructed to evaluate the effectiveness of various vitality administration controllers in a wide range of street situations.
Third, EVREVO. This testing methodology evaluates any analysis software program with out ready for the opposite car components to be put in on it.
Fourth, EV motor check techniques. This check system simulates the driving situations prevailing on roads. This assist the motive force to hone his/ her driving expertise pertaining to completely different parameters. As an illustration, acceleration, deceleration, and different street and cargo situations.
Thereafter, the information collected from these sources is used to establish areas of enchancment within the efficiency and design of an electrical car.
Fifth, enter voltage management. The allowed voltage vary ought to be chosen earlier than the check, and every check level ought to work as shortly as doable.
Sixth, effectivity maps. They’re put in in an electrical car’s simulation mannequin. It offers very important inputs concerning the efficiency of an electrical car’s motor, battery, and different parts.
Seventh, simulation calculation. It may be used to derive the distribution of working factors beneath completely different situations. This may also help to match the motor system to the entire car and get a extra correct effectivity efficiency.
Eight, analytical hierarchy course of (AHP). It’s used to quantitatively measure the relative efficiency of various kinds of batteries. For instance, lithium-ion batteries, gasoline cells, and hybrid batteries.
Ninth, airgap eccentricity. It detects any main defect that will happen in any variable velocity induction motor.
Tenth, enter voltage management. It maintains a particular voltage vary at every level of an electrical car’s motor.
Eleventh, step load testing. On this methodology, a particular load is utilized in incremental steps to an electrical car’s motor. Thereafter, the response of that motor is monitored at every load stage. This permits to evaluate the flexibility of that motor to deal with growing masses with none lower in efficiency or overheating. This helps to find out that motor’s load capability and efficiency beneath completely different situations.
Twelfth, peak load testing. It’s undertaken to judge an electrical car’s motor’s means to face up to any sudden excessive masses or quick bursts of energy demand. On this methodology, that motor is subjected to its most rated load or barely larger than that restrict for a short time period. This helps to evaluate that motor’s means to face up to any such spurt in peak load with out overheating or failing.
Thirteenth, endurance testing. On this methodology, a load is repeatedly utilized to an electrical car’s motor for a chronic interval. One of these testing helps to judge that motor’s reliability, sturdiness, and thermal efficiency beneath extended working situations.
Fourteenth, regenerative load testing. On this methodology, an electrical car’s motor is subjected to variable masses in regenerative mode. This helps to judge its effectivity in each recovering and changing kinetic vitality into electrical vitality in the course of the technique of deceleration.
Fifteenth, thermal load testing. It’s geared toward assessing an electrical car’s motor’s thermal administration system. On this methodology, a motor is operated beneath heavy masses or at most energy for an prolonged interval. Throughout this course of, its change in temperature is monitored. Therefore, this testing helps in figuring out the effectiveness of that motor’s cooling system in order that it may well keep an optimum working vary of temperature.
