Now, Let’s Talk About the Heartbeat of Your EV: The 12-Volt Battery

Many new EV owners are surprised to learn that their electric car still uses a 12-Volt battery, just like a regular petrol car.

So, what does this small battery actually do in an EV like the e.MAS 5? Here’s the simple answer: everything that doesn’t involve propulsion.

Your 12V battery powers:

• The car’s lights, infotainment system, door locks, and sensors
• The onboard computers and safety systems
• The “wake-up” process that allows the high-voltage system to start

If this small battery fails, your EV might not even start, even if the main high-voltage battery is full. It’s the most underrated yet essential part of your vehicle’s ecosystem.

That is why it’s important to replace your 12V battery every 18–24 months, depending on your usage and driving conditions.
