Description

technical field [0001] The invention belongs to the technical field of electric bicycles, and in particular relates to an electric bicycle battery parameter detection device and detection method. Background technique [0002] As the battery of an electric bicycle will age during use, the internal resistance will increase, the capacity will decrease, and the charging tail current will increase. When charging with a charger, it will not be able to change from the equal charge state to the float charge state in time. , severely shorten battery life, and even cause a fire. [0003] If the current state of the battery is detected during the charging process to formulate a corresponding charging method, the service life can be effectively improved and the possibility of fire can be reduced. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an electric bicycle battery parameter detection device and detection method, whic...
