High voltage batteries are not only the largest and most expensive module of any battery electric vehicle, but they also hold a key function for almost any expected feature in a BEV, from performance to security.
The thermal security of high voltage batteries will always be an important issue – especially for the general acceptance of battery electric vehicles. Therefore, preventing incidents relevant to the battery pack’s security by implementing suitable measures is a central aspect of battery development.
Nonetheless, the numbers clearly show that the security of battery electric vehicles is on par with combustion engine vehicles when it comes to both ignition risk and fire load, i.e. the mass of combustible material. However, how a fire progresses is utterly different in these vehicle types.
The final battery is much more than just a case into which the cells are stacked to save as much space as possible, but an integral element of the vehicle’s architecture. Integrating the high voltage battery development into the complete vehicle system of a BEV is one of the most important tasks of any vehicle project.
Higher battery voltage means more energy and higher charging power, plus increased efficiency, better performance and weight savings for EV components such as motors and inverters. But high voltages come with new challenges as well. Here’s a look at why the EV industry is so keen to move to higher voltages—and how engineers are making it happen.
Hitachi Automotive Systems is starting mass production of its 800-volt battery system. The Porsche Taycan was the first production EV with a system voltage of 800 volts, according to Porsche. (Image: Porsche.) Interestingly, EV pioneer Tesla has not committed to shifting to the 800-volt architecture.
