Transit mild hybrid

[Swervyn]

Hullo all. New to this but hope to get some help. Just bought a new transit which has a normal 12v starter, but also a 48v lithium battery to enhance mpg etc.
Thinking of adding a b2b charger to charge my lithium leisure battery when the solar isn't working but some folk have warned me that this may affect the onboard computer system. Anyone had experience of this please?

Too new for me to comment.....

Whoops I did

I guess it will depend how the onboard lithium is being charged?

Other more qualified people will answer soon.

I agree with that. But it should be possible.

Unlike conventional vans, a hybrid and mild hybrid don't have an ordinary 12V alternator. Instead there is a 48V alternator/starter motor, which charges the 48V lithium battery. There is a DC-DC converter which charges the separate 12V battery as required.

The 12V battery is used for the usual vehicle functions like lights, radio, fans and air conditioning, but it doesn't run the starter motor.

The 48V battery runs the starter motor, gets charged up during braking and overrun, and can provide an extra boost of power to the engine for a very limited time.

If you install another DC-DC converter (ie a B2B) to charge a lithium leisure battery, it should work on the same basis as any other 12V item. If you can add extra spotlights and other 12V electrical accessories then a B2B should work just the same. I would imagine in a van intended for work it should be possible to install 12V items you want to use, including a 12V socket.

If you have a 12V socket you could for example charge up a power station (combined battery, charger and inverter) like a Jackery or Ecoflow. A B2B and separate lithium leisure battery would not really be any different.
