A new energy vehicle motor operation detection system and detection method

Abstract

The invention, which belongs to the technical field of motor detection, discloses a motor running detection system and detecting method for a new energy automobile. The detecting system comprises a solar power supply module, a power detecting module, a motor parameter detecting module, a main control module, a fault detection module, an energy compensation module, a warning module, a data storagemodule, and a display module. When the fault detection module detects a locked-rotor fault of a motor, a torque output of a motor controller is stopped timely, so that an IGBT driving module and a motor of the motor controller are protected safely and reliably; and the energy compensation module establish connection between user ravel information and a power supply requirement of a vehicle-mountedpower source and thus power supply is carried out timely by a reserve power supply under the condition of insufficient solar battery power during the full process of working of the vehicle, so that aproblem of sudden insufficient power supply of the vehicle under the condition of not carrying out determination by the user in advance is solved.

Description

technical field [0001] The invention belongs to the technical field of motor detection, and in particular relates to a new energy vehicle motor operation detection system and detection method. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. Solar power generation is a device that uses battery components to directly convert solar energy into electrical energy. New energy vehicles mainly use non-fuel power devices, which do not need to burn gasoline, diesel, etc., but use clean energy, such as electricity, solar energy, hydrogen, etc. In this way, the emission of gases such as carbon dioxide is reduced, thereby achieving the purpose of protecting the environ...

Problems solved by technology

[0004] Existing automotive motors will be blocked due to mechanical jamming or too much external resistance. If the driver continues to step on the accelerator deeply under this working condition, the motor will output high torque at a stalled or extremely low speed, resulting in motor control. If the temperature of the IGBT drive module and motor of the device rises too fast, it will eventually cause damage or burn it out; at the same time, relying on the user's experience to estimate the duration of the vehicle, there may be no fuel or power failure on the way out. Refueling or recharging is required during the period, which will have an adverse effect on time-critical work

[0005] In the existing technology, the detection of the speed, power and other data of the automobile motor cannot be well combined with the actual perception environment
