Abstract

The development of society is restricted by the problem of energy and environment, so battery has been attaching highly importance, lithium battery is widely praised for its high energy density, long cycle life, high open circuit voltage and so on. But the state of the charge of the lithium battery is not yet mature, and it cause a lot of waste of resources. In this paper, a double weighted state estimation system is established based on the characteristics of the lithium battery, the first layer weighted is by using weak signal detection technology, battery resistance measurement is implemented based on AC impedance method, the second layer weighted is by using neural networks, the resistance is the main parameter to achieve the estimation of battery's SOC. A double weighted system consisting of two weighted systems, it can easily achieve the estimation of the internal resistance and state of lithium battery.
