How To Charge Hybrid (Traction) Battery?

Prolong Charger From Hybrid Automotive.

 

There is a last ditch option. If you disconnect the 12v battery for a minute, the ECUs will reset to default values. This defaults your SOC to about 60%, which will allow the car to try to start the engine again. Unfortunately, if the engine doesn't start, you've depleted the battery even further.

If this has already been done a few times, the actual SOC may be too low for this to work.

What is your actual location? There may be someone nearby with a charger if you're lucky.

 

The HV Battery will not charge while the car is in neutral. Techstream will only show the SOC that the car "thinks" is correct.

I think there's a few guys on the forum who have built their own chargers.

This is a relatively inexpensive slightly adjustable DC HV power supply with a 0.1 amp output that would probably work. It would supply a nice slow charge and return the battery to about 50% SOC in a day.

Maxx Volts is a Cheaper option.Check out their Website.

 

$66 or $415....idk

Isn't that $415 just for a charger?
Prolong is $409 just for the charger...

I would imagine each one has about 50 bucks in parts

maybe you can specify cheaper than what??

 

Sorry I thought Maxx Volts had a Gen3 Prius Charger.They only have the Gen2 Prius Charger,My Mistake.Sorry

 

When you say "No Start" do you mean the car powers on but the ICE doesn't start? OR you mean you get nothing on the display. No power at all?

I think you mean the latter.

Buying a high voltage charger will be expensive no matter what and you will use it once most likely. If it was me, I would remove the Hybrid pack and charge modules individually. Takes more time but costs you nothing (assuming you have a simple power adapter to charge each module).

One other option (if you have a fellow Prius driver that could approve the operation) could be to jump your Hybrid pack (parallel connection to another hybrid pack of same kind). It is a risky operation since very high voltage is involved but if done properly it would work. Professor John Kelly of Weber University did that successfully to bring a dead hybrid battery back to life.

You have several options.

 

No, transmission in neutral means no energy flow.

If you can get to ignition on, you can check the HV battery status using a OBDII plug and an app like hybrid assistant.

For charging, you could open up the HV battery and might be able to charge the individual cells. The voltage on each cell is low enough to do this with a standard DC power supply.

 

Hey Pingd,
I'm having almost exact same issue with my 2013 Prius V as you did with your Prius Two - ICE engine started shuddering then lost power and shut down and stalled on freeway. Able to restart the ICE a minute later and limped home. Replace the spark plugs and coils but didn't help with a engine knocking. Cleaned the fuel injectors, RGR pipe, as a result the ICE wouldn't even start now. Depleted the HV battery in the process due to inexperience and too many failed starts. After reading this thread I feel like what a ring prolong battery charger it's probably the only option I have now other than Towing it to a Toyota dealership in San Jose (NorCAL) and having them fix it. If by chance you live nearby in NorCal and still have the Prolong charger I'll be more than happy to cost-share it with you. Also curious as to good cause for your problem, was it the EGR pipe or the intake manifold cleaning that finally fixed it? Thanks.

The INTERNATIONAL POWER IHB250-0.1 looks interesting and the cheap in me wanted SO BADLY to go with that - just I'm at the point time-wise that I need to go for the sure thing.
Hopefully I can find someone to cost share the Prolong (or the battery reconditioning is actually worth it).
Am I correct in thinking that a tow + HV charge up at the Toyota Stealership would be $300+?

iskoos - HSI functioning normally, just the ICE won't stay running (sometimes starts up for a few secs, sometimes doesn't start at all).
My current guess is because the SOC on the HV is too low (says 10.5%).
If the Prius "judges" that the SOC is too low, is there a trouble code that should be thrown?
Parallel HV Jumping ... interesting ... filing that away... do I need a Flux Capacitor also?

If the ICE won't stay running after the HV charge up, I plan to do the: EGR+MAF+Throttle Body+Intake Manifold cleanings, and, new PCV +spark plugs+air filter.
Maybe clean the fuel injectors also - but I've been pretty good about running fuel cleaners & Top Tier gas, so I might skip it this round - gotta get her up and running before there's a mutiny!

Anything else come to mind?
Thank you all - much appreciated![/QUOTE]
