Low voltage battery — Evolving market and technology landscape

Low-voltage batteries are used to power all the accessories in a vehicle including lights; heating, ventilation and air conditioning  (HVAC); infotainment systems and all passive and active safety features.

Be it an ICE vehicle or an electrified vehicle (xEV), the number of features in a car have increased exponentially over the last two decades, which have increased the burden on the electrical system. This requires an efficient low voltage battery system that can enable the electrical architecture to operate without fail. This has led to automakers using multiple batteries rather than just a single 12-V battery, called the starter, lighting, and ignition (SLI) battery. 

Vehicles are now equipped with an auxiliary low voltage battery that supports the increased demand for power. Higher up the segments, some vehicles are equipped with second and even third auxiliary battery to meet the requirement from power hungary applications.

The Low voltage battery — Evolving market and technology landscape report analyzes developments in low battery technology across all propulsion system designs  and also looks at the impact of the key mega-trends in the automotive industry, such as electrification, the advent of 48-V architecture, connected vehicles, autonomous vehicles and software defined vehicles (SDV) on the light vehicle battery capacity.
