Featured Hybrid battery capacity of the Saturn Vue Greenline?

I've come into possession of (2) Saturn Vue 36v Hybrid batteries (2007 and 2009) that were included in a pallet of HV batteries I recently purchased.

Been searching online trying to find the capacity of these batteries, with no luck. Anyone have any information?

Each battery has (3) 12 volt cartridges that would be similar to 2 prius modules mounted in a metal case. Except each of these modules are 6 volts, about twice the thickness of a Prius module, and cannot be separated from each other due to the metal cartridge being spot welded. Discharging to 9.4 volts and end of charge (11,000 mah) is around 14.5 volts.

I've been discharging/charging at increasing levels all week. Being conservative since I don't know their specs. but using a 1.5 amp discharge limit (actually about 0.7amps due to 10w limit) and a 2 amp charge limit. Started at 6000 mah maximum and now I'm at 11,000. It looks like the modules aren't even blinking at 11k charge. The last one I checked had a 10696 discharge after a 11k charge. Been bumping the limit up about 1000mah each cycle trying to find the wall, but getting tired of it, lol. Only completing a cycle a day now. Wondering how far I'm going to need to go.

I could put the discharge to be limited by voltage (9.4) and no limit on charge, hoping the delta v checks will stop the charge when the module is full, but concerned since I can't be here to monitor it continuously.

 

So I've actually disassembled the HV battery into it's components to get a better idea of the battery modules.

The HV battery has 3 cartridges (think of metal boxes) that are each 12 volts.

Each of these cartridges has two modules compressed by the cartridge metal walls and cross bars. There is an aluminum heat sink plate sandwiched between the modules.

Each module is 12volts and made of 10 internal cells. Imagine a prius module that was 24 inches long. Now fold it into a U shape so the + and - terminals are next to each other. This is what it looks like. The terminals on the two modules are connected by busbars in a parallel configuration. This makes the capacity of the cartridge equal to 2x the capacity of an individual module.

The cartridges are connected in series with one another to provide a 36 volt power source. The interconnecting cables look to be ~2 gauge battery cable.

I've now removed all the cartridges from both HV batteries and removed the busbars so I can connect each individual module to its own charger/discharger. I've returned the max mah setpoint to my prius setpoint of 8200 (which would be equivalent to 16,400 using the previous method). This should at least allow me to go through the cycles a bit more quickly. We'll see how this goes.

 

Yeah, I've been researching them a bit. It's a pretty weak attempt at a hybrid. The alternator acts as both 3 phase AC generator and a 3 phase motor. The 3 phase AC passes through a control module (think inverter) which acts as the go-between for the HV battery. The hybrid part is the alternator acting as a 3 phase AC motor to provide some assist to the engine. The ignition key starts the engine (12v starter motor like a normal ICE). The engine shuts off when the car stops, etc, and the hybrid system restarts the engine as needed, until the key is removed. Pretty minimal fuel savings compared to the cost. The batteries got a pretty bad rep due to some early temp sensor problems, but so far they seem to be testing well.
