Optimization of the output voltage of the power battery can improve the overall power and economy of the vehicle to ensure its safe operation.
The power requirement usually depends on vehicle type. For instance, performance-oriented cars and heavy-duty vehicles have different power needs. In some cases, improving power capability has to compromise energy density and increase the cost of thermal/electrical systems, so EV batteries need to balance different aspects of performance.
The low battery capacity and output voltage of the battery cannot enable the vehicle to cope with more complex working conditions. Low voltage affected the power output of the vehicle. The frequent charge and discharge of the battery caused by low battery capacity will have an impact on the battery life.
In addition to battery materials, to minimize safety risk, batteries in EVs are equipped with one or more safety features including fuse, vent, current interrupt device, and battery management system that monitors cell voltage and temperature. Moreover, batteries are protected by a structural frame that prevents battery deformation.
As space and weight in EVs are limited, the batteries with higher energy densities can drive vehicles a longer distance. LIBs have one of the highest energy densities (250–693 Wh/L and 100–265 Wh/kg) of current battery technology, but it is still significantly less that of gasoline.
While low critical mineral prices help bring battery costs down, they also imply lower cash flows and narrower margins for mining companies. Compared to just a few years earlier, overcapacity means that many companies are now struggling to stay afloat (see later section on trends in the EV industry).
