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. In this study, we illustrate validation data-driven numerical method permitting evaluate fast behavior Immersion Cooling Battery Pack. 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...

If battery packs for electric vehicles (EVs) and hybrid electric vehicles (HEVs) are to operate effectively in all climates, thermal management of the packs is essential. In this paper, we will review a systematic approach for designing and evaluating battery pack thermal management systems. A thermal management system using air as the heat transfer medium is less complicated than a system usin...

The lithium ion batteries, thanks to their high densities and high power, became promotes element for hybrid-electric and plug-in electric vehicles. Thermal management of lithium ion battery is important for many reasons, including thermal runaway, performance and maintains a constant temperature during the operating, security, lifecycle. However, in a battery pack, the batteries are stacked ag...

A laboratory-scale passive hybrid power system for transportation applications is constructed and tested in this study. The hybrid power system consists of a fuel cell stack connected with a diode, a lithium-ion battery pack connected with a DC/DC power converter and another diode. The power converter is employed to regulate the output voltage of the battery pack. The dynamic responses of curre...
