Prius 2004 with HYMOTION LITHIUM ION TRACTION BATTERY

Hi guys. I was called today to come diagnose a Prius 04 that could not start.
On getting to where the car was parked, discovered the 12V battery was dead.

The battery would be replaced this weak hopefully, before I continue my diagnosis.

But what baffled me when I opened the rear, was something I have never seen on any Prius before.
It was a kind of like the normal NIMH traction pack, in configurations and size. On reading the cover, it was written HYMOTIONG LITHIUM ION INSIDE.

Some questions
1. Has anyone here own a Prius with such a technology side by side with the original NIMH traction battery in the hatch?

2. What does the hymotion lithium ack do? Does it support the main traction battery, or ....?

3. Is the hymotion lithium pack in the rear as a range extender of some sort?


Thanks for your responses.

Pls does anyone have a hymotion manual, showing how to removed the hymotion pack from the car entirely, revert the system to using the stock hybrid battery?

Thanks guys

 

Thanks sir. Would go through all the links

 

I see that the L5 charges requiring 120VAC in North America, etc.
Here's my question:
Can a 220VAC power source, as is obtainable in Nigeria used to charge the hymotion pack? Would there be cable heating problems?

Thanks for your replies.

 

Thanks Eric, would have the 12V battery replaced first and see how things go.
