Environment art mower battery pack management system and control method

Abstract

The invention discloses an environment art mower battery pack management system and a control method. The environment art mower battery pack management system comprises a detection module, a system controller, a motor driving module, a fault switch group, a system power supply, and a human-computer interface. According to the system controller, through the battery monomer voltage, the battery pack voltage and current obtained by the detection module, by combining with fault information fed back by the fault controller, the fault information is judged and generated according to battery state information, battery monomer voltage and the like, so that corresponding switches in the fault switch group are switched on, two motor drivers in the motor driving module are controlled, and the fault information is fed back to a battery state predictor. Meanwhile, the invention further provides a control method of the environment art mower battery pack management system. Fault judgment can be carried out on one or more battery monomers at the same time, the corresponding fault battery monomers are actively cut off, continuous power supply of the battery pack is guaranteed, and frequent replacement of the fault battery monomers is not needed.

Description

technical field [0001] The invention relates to the technical field of battery pack management, in particular to a battery pack management system and control method for a Huanyi mower. Background technique [0002] With the rapid improvement of people's economic level and requirements for the ecological environment, urban environmental art greening has received more and more attention in urban construction. Green grass can be seen everywhere in the city, and environmental lawn mowers are also widely used for lawn cleaning. At present, environmental lawn mowers are mainly divided into electric lawn mowers and oil-powered lawn mowers. However, oil-powered lawn mowers are fuel-intensive and pollute the environment on the one hand; , so it is becoming more and more difficult to be suitable for use in cities, especially public green spaces and family green spaces. Electric lawn mowers are increasingly becoming the main force in the development of Huanyi lawn mowers because of th...
