“…Random-variable current affects battery degradation rate, which results in the fact that lithium battery degradation function is a nonlinear time-varying function influenced by random effects. Therefore, random-variable current RUL prediction is an enormous challenge [59]. Searching for current rules and the RUL influence becomes the key to this problem.…”

Lithium-ion batteries are the primary power source in electric vehicles, and the prognosis of their remaining useful life is vital for ensuring the safety, stability, and long lifetime of electric vehicles. Accurately establishing a mechanism model of a vehicle lithium-ion battery involves a complex electrochemical process. Remaining useful life (RUL) prognostics based on data-driven methods has become a focus of research. Current research on data-driven methodologies is summarized in this paper. By analyzing the problems of vehicle lithium-ion batteries in practical applications, the problems that need to be solved in the future are identified.

“…The lithium battery degradation rate is greatly influenced by the ambient environmental temperature [56][57][58][59]. The lithium battery may burn as the car starts in a below-freezing environment and as battery capacity rapidly fades under high-temperature conditions [60].…”

“…Systems consisting of multiple packs are either controlled by a joint master or operated completely independently to expand the redundancy. The master, as the main intelligence of a battery, has various responsibilities [45]: These functions on the software side of the BMS can be structured according to Figure 10. Battery states such as state of charge (SoC), state of health (SoH) and state of function (SoF) are calculated by the measured current, voltage and temperature of the single cells.…”

Battery Design for Successful Electrification in Public Transport

et al. 2015

Abstract:Public transport is an especially promising sector for full electric vehicles due to the high amount of cycles and predictable workload. This leads to a high amount of different vehicle concepts ranging from large batteries, designed for a full day of operation without charging, to fast-charging systems with charging power up to a few hundred kilowatts. Hence, many different issues have to be addressed in the whole design and production process regarding high-voltage (HV) batteries for buses. In this work, the design process for electric public buses is analyzed in detail, based on two systems developed by the research projects Smart Wheels/econnect and SEB eÖPNV. The complete development process starting, with the demand analysis and the operating scenario, including the charging routine, is discussed. This paper also features details on cell selection and cost estimations as well as technical details on the system layout, such as the management system and passive components as well as thermal management.

“…Because of chemical reason, battery needs to be protected from overcharged, thus prevents it from irreversible chemical reaction which damaging cells inside battery and led to a decreased performance and decreased capacity of battery energy storage [3]. Battery Management System (BMS) has many functions to help the user to manage battery and prevent it from charging failure [4]. Battery protection, battery monitoring, and optimization are some among the functions that a BMS has to be provided by.…”
