The invention discloses a lithium ion battery residual life prediction system and a control method thereof. A lithium ion battery to be detected is conveyed into the constant-temperature detection chamber through the magnetic limiting device on a conveying belt, an electromagnetic adsorption device connects the battery to be detected to the battery circulation testing device for charging and discharging testing, and a lithium ion battery capacity prediction software automatically collects and processes test data and outputs a capacity attenuation curve of the lithium ion battery. Therefore, the purpose of predicting the residual life of the lithium ion battery is achieved. Under the same test condition, the prediction accuracy of the lithium ion battery residual life prediction system and the control method thereof is higher than 90%. Therefore, the lithium ion battery residual life prediction system and the control method thereof have a certain application prospect in the field of health management of lithiu
