12V Power in Your BYD Shark 6 Tub – Always On, Always Ready

The BYD Shark 6 doesn’t include factory-fitted 12V outlets in the tub, so we’ve engineered a proven solution: a tested, real-world, 10-month-validated 12V accessory power system that stays on all the time — even when the vehicle is turned off and locked.

This kit works on either side of the tub. On the passenger side you’ll use the full cable, and on the driver side you can trim it to length or simply loop the extra.

How It Works

The Shark runs both a high-voltage (traction) battery and a low-voltage system. A built-in DC-DC converter continually keeps the 12V battery charged, and importantly, this charging continues even when the vehicle is off or locked — as long as the high-voltage battery remains above ~20% state of charge.

This kit supports a total combined load of up to 50A across both outlets. For example, if the cigarette socket is drawing 10A, the Anderson plug can supply up to 40A. The cigarette socket itself is rated for up to 180W (15A), so if you’re using the full 15A on that outlet, the Anderson plug should be limited to 35A to remain within the cable and fuse ratings. Most vehicle 12V cigareete sockets are only rated to 120W / 10A so this will exceed all automotive default rartings for standard 12v accessories.

Realistic Runtime Expectations

For those not familiar with electrical systems, here’s an easy rule of thumb:

With a full high-voltage battery, the Shark can run a medium-sized 12V fridge for up to ~30 days without driving, charging, or running its petrol generator (assuming a normal 30–50% fridge duty cycle).
In more realistic scenarios — for example, parking with 50% traction battery — you can expect around 7 days of fridge runtime before the system reaches the Shark’s 20% limit.
If the battery does drop too low, the Shark will automatically start its onboard petrol generator for about 10 minutes, which typically provides 12–18 hours of additional 12V runtime. This happens automatically and safely.

In short: If you’re camping, touring, or driving every couple of days, your 12V accessories will run continuously without issue. For longer periods with no driving or charging (7+ days), we recommend turning off high-draw 12V loads.

Our Long-Term Test Results

We’ve been testing this setup in our own BYD Shark since January 2025, running a 45L 12V fridge and a Starlink Mini 24/7. After 10+ months of continuous use:

We have never had a flat 12V battery.
The high-voltage system has behaved normally in both EV and hybrid modes.
During overnight camping, the vehicle has occasionally started the petrol generator automatically for 10 minutes to top up — exactly as designed.
When using the Shark’s SAVE mode set to 30–35%, we found the system does not need to auto-start overnight at all, keeping 12V loads running without interruption.

We’ve also installed this setup in several friends’ and family members’ Shark vehicles with identical results. We are fully confident in the long-term reliability of this upgrade.

Installation Options

DIY Kit: Full kit supplied with step-by-step instructions. Installation requires soldering two wires on the connection as the wires must pass through the factory Shark rubber grommets in bare form. For this reason this connection cannot be shipped pre-attached.
Professional Installation: Available at our workshop in Braeside, Victoria.
