“…In some studies, [27][28][29] the increase (or decrease) in the battery power amplitude and variance can lead to an increase (or decrease) in the battery life attenuation. For the optimal power distribution at 25°C, according to the method of evaluation of the energy management strategy in Choi et al, 30 combined with equation (36), the mean square error s of the battery power is calculated as…”

This article presents an energy management approach for the hybrid energy storage system in an electric bus at different temperatures. An electric bus equipped with a semi-active hybrid energy storage system is considered as the research object. According to the urban climatic characteristics of the vehicle running, the convex optimization approach considering temperature factors is proposed. The purpose of this study is to minimize the energy loss and maximize the discharge and charge depth of the super capacitor. Simulation results show that the comprehensive energy efficiency of the proposed method is 83.31% and the comprehensive energy efficiency is improved by 2.42% at 25°C, which is compared with the rule-based power allocation method based on urban driving cycle in Harbin, China. When the ambient temperature is 25°C, the comprehensive energy efficiency of the proposed method is 81.03%. This result is improved by 1.45% and the battery power variance at 25°C is reduced by 20.11% compared with the rule-based power allocation method. Therefore, the proposed power distribution method can effectively improve the functioning of an electric bus at different temperatures.

“…If the capacitors and inductors of the impudence network are appropriately determined, the proposed converter can function effectively in a wide range of voltages and loads despite discontinuous input voltage [28]. Compared to conventional Z-source DC-DC converters, the proposed converter elevates output DC voltage as the number of active elements are reduced.…”

“…In Ref. [19], the I-V characteristics of a battery were obtained by establishing an RC equivalent circuit model, after which the operating characteristics of the battery were emulated using a DC-DC converter. No specific model parameter identification method was given, and its applicability was limited.…”

Real batteries used for the performance testing and evaluation of the drive systems of electric vehicles (EVs) are being replaced by battery emulators (BEs) because of the high test costs, long test cycles, and difficulty in adapting to extreme operating conditions associated with the use of real batteries. A parametric BE for a lithium‐ion battery based on a voltage source converter is presented. First, a Thevenin model of the battery is established, and a parameter identification method is proposed to obtain the relationship between the parameters of the battery model and the characteristics of the external electrical port (i.e. I–V characteristics) of the battery. Subsequently, based on the I–V characteristics, the topological structure of the power electronic device of the BE is designed, and the working modes under charging and discharging conditions are presented. Finally, an experimental prototype of the BE is designed and tested. The experimental results show that the proposed BE power converter can successfully simulate the external port voltage and current characteristics of the battery, which can replace the real battery to provide an effective test environment for the test and evaluation of the electric drive system of EVs.
