Where is the Tesla small battery located?

Tesla's small battery is located on the chassis of the car. The space occupied by the electric vehicle battery pack is relatively large, so it can only be fixed on the car chassis. Tesla's models include Model S, Model X, Model Y, and Model 3. Taking Tesla's flagship product Model S as an example, it has 7,000 battery cells. The Model S is a mid-to-large-sized car under Tesla, with a body structure of a 5-door, 5-seat hatchback. The vehicle dimensions are 4979mm in length, 1964mm in width, and 1445mm in height, with a wheelbase of 2960mm. In terms of suspension, the Tesla Model S adopts a double-wishbone independent suspension and a multi-link independent suspension.
When working on a Tesla, I noticed the auxiliary battery is usually hidden behind the lower panel in the front trunk, especially in Model 3 or Y. You just need to lift that soft cover to see it. The 12V battery mainly powers vehicle startup and low-voltage components like lights, unlike the high-voltage main battery pack, so its location allows for easy maintenance. I suspect Tesla placed it here to isolate high-voltage risks, given the compact engine bay layout—positioning it in the front trunk prevents accidental contact with high-voltage wiring. If you occasionally notice flickering screens or headlight dimming, it might signal an aging auxiliary battery, so replace it promptly to avoid roadside breakdowns. Remember to disconnect power before swapping the battery and keep the key aside to prevent accidental short circuits. Overall, the location is easy to access, but handle with care—lift the cover gently to avoid scratching plastic parts, as repair costs aren’t cheap.
