A new hybrid system of a tracked bulldozer is designed, which primarily consists of an engine-generator set, a battery pack, and a supercapacitor. According to the power requirements of typical working conditions and the output feature of three power sources, a fuzzy control and wavelet transform-based energy management strategy is proposed. Models of the hybrid system are built in Matlab/Simul...

The availability of new high density FPGA technologies enables innovative approaches to the architecture of onboard computer systems (OBCS) for demanding small satellite applications. In the paper, we present the architecture of a highly integrated satellite computer exploiting the powerful features of Xilinx’s Virtex-II Pro FPGA technology. The computing resources of the “Flying Laptop” satell...

ABSTRACT In this paper, a configuration of electric energy storage system for Hybrid Electric Vehicles has been proposed that consists of a small battery and ultracapacitor pack coupled to the vehicle bus through dc-dc converters. The entire system, together with necessary power electronics pack, has been modeled and a Model Predictive Controller (MP...

Thermal management is an important part during the development of a hybrid or electrical vehicle. This concerns several components in the electrical network of a car, the most important being power electronics and a battery pack. Electrothermal simulation is required at the system level in order to choose the best regime that complies with all thermal requirements and an important problem is ho...

Thermal management of Lithium-ion batteries is a key element to the widespread electric vehicles.

First, an experiment using set up immersion cooling battery pack, where temperatures, voltage and electrical current evolution Li-ion are monitored. The impact diff...

We present a new approach to fabricate an integrated power pack by hybridizing energy harvest and storage processes. This power pack incorporates a series-wound dyesensitized solar cell (DSSC) and a lithium ion battery (LIB) on the same Ti foil that has double-sided TiO2 nanotube (NTs) arrays. The solar cell part is made of two different cosensitized tandem solar cells based on TiO2 nanorod arr...

In the application of a long series battery group, an inter-pack imbalance is inevitable. No intra-pack cell equalizer can prevent pack-level over-discharge. A bimodal, multichannel pack based on quasi-resonant, two-transistor forward converter proposed to solve this problem and achieve tradeoff between balancing efficiency speed. This has two modes: pack-to-pack-group pack-to-any-pack (P2PG&am...

A reduced-order model ROM is developed using proper orthogonal decomposition POD for a physics-based lithium-ion battery model. The methodology to obtain the proper orthogonal modes and to analyze their optimality is included. The POD-based ROM for a lithium-ion battery is used to simulate a charge/discharge process and the behavior of a battery pack. Compared to the physics-based model, the co...
