The adoption of electric vehicles (EVs) is faring well, and the outlook is promising for the EV industry. Despite this, significant technical gaps still exist that mainly concern battery capacity, cost and performance.
Battery management systems (BMSs) play a major role in optimising the use of ever-increasing large battery stacks by improving endurance, performance and reliability. They ensure proper charge and discharge of lithium battery packs which controls the temperature of each lithium cell to avoid hazardous breakdowns, and also balances and protects each cell in the system. BMSs are key components of EV batteries, typically representing about 15 % of overall system costs.
