Abstract

Abstract:

This paper quantitatively evaluated the energy saving effect and investment cost of the plug-in hybrid electric vehicles (PHEVs) with Low Temperature Radiator (LTR) for batteries. Designed the two kinds of battery cooling architectures equipped with and without LTR and its control logic, and propose three user actual driving conditions as commuter, trip and travel. After analyzed the benefits of the two kinds of battery cooling architectures in single drive cycle and the average annual energy saving of some typical cities in China, the cost performance of the two architectures were compared. The results show that under single low load cycle, the working interval of LTR with profit is 24~27 ℃. At the user actual driving frequencies discussed, the benefit of battery cooling system with LTR is less than 3.14 CNY per year, which does not match Its cost input. It is recommend to cancel the LTR in the battery cooling system of PHEVs.

Key words: plug-in hybrid electric vehicle (PHEV), battery thermal management systems, low temperature radiators (LTR), energy saving
