LEAD-ACID BATTERY

Electric mobility is a massive trend of the future, in particular when it comes to vehicles used for short, local trips. When we think of electric cars, we often immediately think of lithium-ion traction batteries, which have nominal voltages of several hundred volts; we tend to overlook the fact that every electric car is also equipped with a 12-volt lead-acid on-board electrical system battery. This on-board electrical system battery (also known as an auxiliary, backup, support, additional or second battery) plays an important role in electric mobility and Banner always has the right solution here.

Here are just some of the reasons why the lead-acid battery remains relevant for electric cars:

• 12-volt on-board power supply: Electric cars also use 12-volt electrical consumers (e.g. central locking, interior lighting, infotainment system, etc.). These have been perfected over decades and are used in both combustion engines and electric cars.
• Safety requires redundancy: The 12-volt backup battery also serves as a buffer to ensure functional safety aspects. For example, the power steering must continue to work when the engine is switched off in order to maintain the vehicle's manoeuvrability.
• Part of electric mobility: Renowned vehicle manufacturers also rely on lead-acid batteries to supply the vehicle’s electrical system. The all-electric BMW i3, for example, is stabilised with a Banner lead-acid battery, which supplies the 12-volt electrical consumers in the car.

The lead-acid battery is therefore also an indispensable component of electric mobility and ensures the stability and availability of the on-board electrical system in electric vehicles.
