Volvo files patent for smart battery that can ‘think’
Volvo has patented the first smart battery for electric cars that can “think” and manage its energy more efficiently.
The development of batteries for electric cars continues to progress, and new technologies have appeared over the years. The various players in the market are constantly seeking to improve the performance, safety and autonomy of batteries.
To go even further, several research projects around smart battery cells are currently being carried out: indeed, Volvo has recently filed patent for a smart battery for electric vehicles. This patent was filed by inventor Markus Ekström on behalf of Volvo Cars.
A smart battery for future Volvos
This smart battery for electric vehicles will promote a more efficient use of energy stored, in order to provide a better autonomy to use. In this way, future electric vehicles from Volvo equipped with this technology will be able to be charged faster and travel longer distances.
This new battery technology from Volvo is intelligent, and is able to “think”: in other words, it will be able to “read” and understand its environment. It will thus be able to obtain data from each battery cell, in order to regulate, on the basis of this information, its behavior with the aim of optimizing its performance.
Although few details have yet been revealed, Volvo’s idea is to develop a battery that charges more efficiently and fasterand is able to last longer while providing greater autonomy.

Critical battery status information
Currently, electric vehicle battery packs are made up of several modules, comprising thousands of cells. One of the biggest challenges for the automotive industry is to ensure efficient communication between each of these cells, in order to optimize battery charging and discharging, in addition to electronic battery control systems.
Volvo’s technology seeks to tackle this problem differently, with a smart battery that would be able to control and monitor the status of each cell independently. The various sensors of the battery would make it possible to measure the temperature, the pressure, the expansion and the chemistry of each cell, or even their state in the event of shock.
This information is crucial in deciding the right battery power managementto optimize its performance for automotive use.
