Abstract

The embodiment of the invention discloses a motor drive control device, which comprises a battery, a motor control module and a motor. The battery comprises a battery management module, wherein the battery management module is used for calculating the dischargeable power of the battery. The battery management module is electrically connected with the motor control module, and is used for transmitting the dischargeable power of the battery to the motor control module. The motor control module is electrically connected with the motor, and is used for adjusting the motor setting input power to beless than or equal to the dischargeable power of the battery when the motor setting input power is greater than the dischargeable power of the battery, so that the battery outputs the adjusted motorsetting input power to the motor. The technical solution provided by the embodiment of the present invention can solve the problem that the motor control module of the existing marine electric propeller cannot obtain the dischargeable capability of the battery, so that the input power of the motor cannot be adjusted according to the change of the dischargeable capability of the battery.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electric energy storage and power supply, and in particular to a motor drive control device and control method. Background technique [0002] Marine electric propulsion refers to the electric motor equipment that is powered by a secondary battery and the extended end of the motor shaft directly drives the propeller. It is often used in leisure fishing, tourism and water sports and other occasions. And compared with gasoline outboard motors or diesel outboard motors, marine electric propellers are less noisy and more environmentally friendly, making users use marine electric propellers more and more frequently. [0003] As the battery is used, the power of the battery gradually decreases, and its discharge capacity also decreases. In the prior art, the battery management module (Battery Management System, BMS) inside the battery generally only sends battery status parameters such as ...
