Abstract

The invention provides a user maintenance system of a networked electric vehicle. The user maintenance system is used for protecting a battery of the networked electric vehicle, and the networked electric vehicle comprises a battery management system, and the user maintenance system comprises an information acquisition module configured to acquire calculation information of the state of charge ofthe battery in the battery management system and information about the balance state of the battery; a calculation module configured to judge whether maintenance is needed or not according to the calculation information of the state of charge of the battery and the information about the balance state of the battery to obtain a judgment result; and a control module configured to receive the judgment result and send control information about battery maintenance to the battery management system. According to the user maintenance system, the battery equalization state can be timely acquired and the control information about battery maintenance can be timely sent so that vehicle maintenance can be timely started, and the service life of the battery can be prolonged and the endurance mileage ofthe vehicle can be increased and the influence of the endurance mileage of the existing pure electric vehicle on the user experience can be reduced.

Description

technical field [0001] The invention relates to the field of vehicle technology and the field of new energy technology, in particular to a user maintenance system and a control method for networked electric vehicles. Background technique [0002] In recent years, my country's automobiles have begun to enter a period of rapid growth, and will maintain a high-speed growth trend in the next few years. Under the influence of the current energy shortage and serious environmental pollution, countries around the world have issued a series of policies to encourage the development of new energy vehicles. Pure electric vehicle (EV) is one of the most promising directions. [0003] After the existing pure electric vehicle battery pack is used for a period of time, the SOC (State of Charge, battery state of charge, also called remaining power) of the battery pack will often appear different, which will affect the charging time and life of the battery pack. , which in turn affects the ...
