Liquid fuel has been the main source of energy in internal combustion engines (ICE) for decades. However, lithium-ion batteries (LIB) have replaced ICE environmentally friendly vehicles and reducing fossil dependence. This paper focuses on comparative analysis battery thermal management system (BTMS) to maintain a working temperature range 15–35 °C prevent runaway high gradient, consequently in...

Balancing the lithium-ion battery pack is essential to enhance energy usage and life cycle of battery. This paper analyses passive cell balancing method Li-ion for e-mobility application based on loss cost estimation through simulation hardware implementation. As a part simulation, an electrical equivalent circuit model developed parameters are obtained using electrochemical impedance spectrosc...

Electric vehicles (EVs) are now an important part of the automotive industry for two main reasons: decreased reliance on oil and reduced air pollution, which helps us contribute to development environmentally friendly environment. EV buyers examine overall vehicle mileage, recharge time, mileage after every charge, batteries charging/discharging security, lifespan, charged rate, capability, tem...

The battery management system (BMS) of a hybrid-electric-vehicle (HEV) battery pack comprises hardware and software to monitor pack status and optimize performance. One of its important functions is to execute algorithms that continuously estimate battery state-of-charge (SOC), state-of-health (SOH), and available power. The accuracy of these algorithms is critical for the proper sizing of the ...

In the electricity market, customers have many choices to reduce electricity cost if they can economically schedule their power consumption. Renewable hybrid system, which can explore solar or wind sources at low cost, is a popular choice for this purpose nowadays. In this paper optimal energy management for a grid-connected photovoltaic-battery hybrid system is proposed to sufficiently explore...

This paper describes the development of a Battery Management System (BMS) State of Charge/Health (SOC/SOH) algorithm that was developed and proven for three different lithium ion based cell chemistries (nanophosphate, lithium manganese oxide, lithium iron phosphate). In addition, a universal BMS architecture based on this algorithm was developed that can support other chemistries, capacities, a...

The advantages of lithium-based batteries over lead acid batteries have created great interest in developing safe and cost effective drop-in replacements. To achieve the required cost effectiveness and safety of the battery, Battery Management Systems (BMS) are critical to avoid over-charging, over-discharging, and continuously and accurately determining the State of Charge (SOC), State of Heal...
