“…Testing the characteristics of the battery voltage against the time was carried out during constant loading to determine what the maximum current was and what the maximum load limit that might be used when discharging was, and what the maximum charge limit on the battery when it started to stop discharging so that there was no over-discharge [26] [27]. The battery capacity is in excess condition or vice versa, and the minimum battery charge when it should not be used when discharging.…”

The battery is the main component both as an energy provider and as an interface for several systems in an electric vehicle. It has three important parameters: current, voltage, and temperature that must be maintained as the battery can have a harmful reaction that can lead to overcurrent. The battery must also not overcharging or discharging for too long because it can cause damage and affect its lifetime. Another error that can arise is sensor failure due to the interference or noise that can cause an error in data reading. To prevent this problem, it needs protection by means of isolation in operating the battery. In this research, planning in optimizing battery work was conducted by designing the process of detection and isolation of faults that occurred in batteries, particularly lithium polymer battery to reach their more optimal and good performance. Battery modeling was needed as the parameter identification, and the Kalman Filter algorithm was applied to help to reduce the detection rate and fault isolation. The results of detection and isolation of overcurrent and sensor failure using Kalman Filter were found quite accurate. In overcurrent isolation, a discharge current of 6A was obtained from the maximum current limit of 10 A, and for sensor failure isolation, the Kalman Filter algorithm succeeded in improving the results of the previous reading.

The increasing environmental pollution caused by fossil fuel emissions from vehicles using internal combustion engines has spurred the development of electric vehicles. The power sources for the electric vehicles to operate are often stored in different types of batteries with different charging requirements. Most batteries are charged from the grid sources through AC/DC converters for charging battery packs. An effective charging system usually consists of a rectifier and a dual-active bridge (DAB). A typical controller consists of the control of DC bus, PFC (power factor correction), constant voltage (CV), and constant current (CC) for the battery. However, most conventional chargers only regulate the voltage or current of the battery when charging. These types are mainly suitable for lead acid types and the power factor correction has not been considered. Meanwhile, new generation battery packs as lithium-ion batteries require charge of CC at first. When the battery charging voltage reaches a certain voltage threshold, then switch to the mode of CV charge. Basing on the analysis of the battery charging requirements of electric vehicles, this paper presents a battery charger control solution with capability of CC and CV control as well as high power factor. The simulation results on MATLAB/Simulink have validated the effectiveness of the presented method.

“…ISC is widely cited as the most common cause for thermal runaway [4], [5]. Electrical abuse can be separated into the mismanagement of the battery's health and external short-circuiting [6]. Thermal abuse is a local overheating that isn't caused by a previous mechanical or electrical abuse scenario that is almost exclusively caused by a loose contact on the cell connector.…”

“…If a thermal runaway event is caught in its early stages, prevention mechanisms can be triggered, and the damage caused minimised. Utilising the battery management system's (BMS) ability to monitor the voltage, current, and temperature is vital in the early detection of an ISC-induced thermal runaway event [6]. Detection of battery ISC is not an industry standard and many different approaches are currently being evaluated in research.…”

The production of electric vehicle battery packs with ever-increasing energy densities has accelerated the electrification of the world's automotive industry. With increased attention on the electric vehicle markets, it is vital to increase the safety of these vehicles which now hold higher hazardous potential. This paper aims to explore the field of pack-level thermal runaway mechanisms and evaluate potential mitigation strategies. Most available literature concentrates on the micromanagement of thermal runaway whereas this paper takes a more holistic approach. Thermal simulations for analysing thermal runaway of modules in differing locations are run to characterise the behaviour of a thermal runaway event at pack-level. Results suggest that the propagation of thermal runaway is consistently severe in a cooling plate cooled battery pack as the cooling plate acts as a channel for high temperatures. Additionally, thermal insulation added to contain the rapid increase in temperature unfortunately results in wider spread higher temperatures.
