Increasing the number of EV charging piles has a significant impact on battery electric vehicle sales but not on plug-in hybrid electric vehicle sales. 1. Introduction
As the number of cells increases, the thermal runaway occurred at lower external heating, indicating a higher fire risk. Moreover, a simplified heat transfer model was proposed to demonstrate the effects of pressure and battery pile size on thermal-runaway criteria.
Furthermore, high-power direct-current (DC) charging piles, which are unsuitable for home installation, can provide much faster EV charging, making them ideal for urban areas, such as Madrid and Manhattan, where parking costs are high (Faria et al., 2014).
It is because the exothermic reaction is less intense at a low pressure, which needs more time to provide energy for thermal runaway. For larger battery piles, reaching the battery’s minimum thermal runaway energy is postponed due to the large fuel loads. In the real scenario, such a time delay can be regarded as the effective fire prevention time.
Increases in commercial land prices, which reflect the prosperity of local businesses, have a positive impact on the diffusion of AC charging piles but a negative effect on DC charging piles, which require a higher initial investment and incur higher operating costs.
For instance, at −40 ℃, commercial 18,650 LiBs can only provide 5% energy and 1.25% power when compared with values obtained at 20 ℃, significantly reducing the range of the EVs. Furthermore, when forcibly charging LiBs at low temperatures, the lithium deposition on the negative electrode surface can dramatically reduce the life cycle of LiBs .
