The new developed strategies include back propagation (BP) neural network, radial foundation operate (RBF) neural network, fuzzy logic strategies, help vector machine, fuzzy neural community, and Kalman filter. The adaptive methods are self-designing ones that may be automatically adjusted in altering systems.

The RBF neural community has been utilized in SOC estimation. The method was examined with information which was from battery experiments. Results present that the operation velocity and estimation accuracy of estimating model can meet the demands in follow, and the mannequin has sure worth of application . Recently, with the event of artificial intelligence, numerous new adaptive methods for SOC estimation have been developed.

As batteries have been affected by many chemical components and have nonlinear SOC, adaptive systems supply good solution for SOC estimation . To improve the Coulomb counting technique, a new approach known as modified Coulomb counting technique is proposed.

The RBF neural network is a useful estimation methodology for techniques with incomplete information. It can be used to investigate the relationships between one major (reference) sequence and the opposite comparative ones in a given set.

Do additional research on the sensible universal software of the strategies. Since the energy storage methods have been highlighted in moveable electronics and hybrid electrical automobile purposes, the estimate accuracy of SOC turns into increasingly necessary. In latest years, many scholars have carried out a lot of analysis on SOC estimation.

The modified Coulomb counting technique uses the corrected current to improve the accuracy of estimation. Among the methods which have been employed, impedance measurements present information of several parameters, the magnitudes of which can rely upon the SOC of the battery. Table 1 presents the particular SOC estimation methods in view of the methodology. The purposes of particular SOC estimation methods in battery management system (BMS) are consequentially completely different.

The estimate accuracy has improved continually, and it can be anticipated that intense research and growth efforts are already on observe. In order to additional improve SOC estimates, combined with some literatures, anticipated enhancements for the additional research embrace the next areas. Using actual-time measurement road knowledge to estimate the SOC of battery would usually be troublesome or costly to measure. In , software of the Kalman filter methodology is shown to offer verifiable estimations of SOC for the battery through the actual-time state estimation.
