Sliding average algorithm for hybrid energy storage system

Is a sliding mode control-based current sharing algorithm suitable for hybrid energy storage system?

Conclusions In this paper, a sliding mode control-based current sharing algorithm for Hybrid Energy Storage System is proposed that also features uninterruptible supercapacitor cyclic charging, while having HESS on the discharge mode.

What is a hybrid energy storage system?

While a proper DoD can be met with smart integration of State of Charge (SOC) control into the power management schemes, the discharge rate control demands storage units with higher transient response capabilities and tolerance levels to be integrated with batteries and form a Hybrid Energy Storage System.

How to optimize hybrid energy storage system?

Dynamic programing approach is used to optimize the hybrid energy storage system. Components sizes and the system control strategy are optimized simultaneously. The life cycle cost of the system is rapidly reduced initially with SC increases. Four control rules are extracted from the DP results to obtain an on-line strategy.

What is a hybrid energy storage system (Hess)?

1. Introduction Hybrid energy storage systems (HESSs) have become more and more important in hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and all-electric vehicles (EVs) due to the high cost of replacing the battery during the life of the vehicle .

Is a sliding-mode controller effective compared to a fully-active Hess?

Compared to the result of fully-active HESS, the bus voltage of semi-active HESS has slight ripple due to the battery voltage dynamic. The SC current is robustly tracked with smooth transition when the load power switches. Hence, the effectiveness of the proposed sliding-mode controller is verified.
