Abstract

The invention discloses an embedded intelligent multi-sensing system oriented to a power lithium battery. The system comprises a temperature sensor, a pressure sensor, a gas sensor and a read-out circuit chip packaged into a tube shell by adopting a system-level package technology; the temperature sensor, the pressure sensor, the gas sensor and the read-out circuit chip in the tube shell accomplish the wire bonding by using gold wires so as to realize electric signal transmission; the temperature sensor, the pressure sensor and the gas sensor are connected with the read-out circuit chip through a switch module; the switch module inputs the input signal into the read-out circuit chip according to the predetermined selectivity. By designing the embedded micro intelligent multi-sensing system is designed in the original power lithium battery, multiple-state information in the power battery can be timely acquired, thereby accomplishing the index prediction by starting the information processing based on the state information.

Description

technical field [0001] The invention relates to the technical field of lithium battery detection, in particular to an embedded miniaturized intelligent multi-sensing system for power lithium batteries. Background technique [0002] At present, while using lithium batteries, they will be equipped with battery management systems to monitor and manage lithium battery packs. The battery management system takes the power lithium battery pack as the core. By detecting the external temperature, current and voltage of the power battery pack, and then using the lithium battery model and algorithm, the power lithium battery's state of charge, health status, remaining service life, etc. are obtained. Indicators form the basis for security assessment and manage and balance based on this. However, the existing battery management system does not respond in time when a danger occurs, and cannot realize early warning and take effective measures. The main reason is that the data used by the...
