Abstract
This paper introduces improvement efficiency of battery for air-conditioning (A/C) system. Super-capacitor (SCs) is mounted with Lithium-ion battery called hybrid energy storage system (HESS). The system modeling of heat system in passenger room and battery pack are derived to represent system in mathematic model. The characteristic of power loss relative to discharge rate are examined using several models of Li-Ion battery. The relationship between discharge rate and power loss in battery is tested by experiment kits. A/C system of passenger car is simplified to demonstration kit. Single energy storage system (SESS) and HESS batteries are used as energy storage. The both typed of energy storage are tested with on-off control. HESS outperforms rather than SESS. The efficiency of HESS battery is greater than SESS about 57.57% at peak load and 14.34% at rated load.
Highlights
Nowadays, the pollution problem is increasing which causes global warming, so the amount of electric vehicle (EV) are increasing to reduces the pollution problem [1]
The peak load of battery pack is main cause which reduce the efficiency of energy consumption in air-conditioning system (A/C) system
This research will introduce heat balanced of automotive A/C system, characteristic of battery pack and improvement of efficiency and power loss of battery at peak. on-off control system is used to demonstrate energy consumption of storage system (SESS) and hybrid energy storage system (HESS)
Summary
The pollution problem is increasing which causes global warming, so the amount of electric vehicle (EV) are increasing to reduces the pollution problem [1]. The single type of battery cell is wellknown as single energy storage system (SESS). The peak load of battery pack is main cause which reduce the efficiency of energy consumption in A/C system. Li-Ion. Supercapacitor obtains discharge rat greater than others battery types so that it can reduce the peak current of battery pack. Supercapacitor obtains discharge rat greater than others battery types so that it can reduce the peak current of battery pack They have many advantages such as large discharge current in short time, low internal resistance, wide range operation temperature, and longlife cycle time. This research will introduce heat balanced of automotive A/C system, characteristic of battery pack and improvement of efficiency and power loss of battery at peak. On-off control system is used to demonstrate energy consumption of SESS and HESS This research will introduce heat balanced of automotive A/C system, characteristic of battery pack and improvement of efficiency and power loss of battery at peak. on-off control system is used to demonstrate energy consumption of SESS and HESS
