time to take a peak inside that BMW 530e plug in hybrid high voltage battery pack

[Gregski]

seems like all we have to do is remove 864 torx screws

[Gregski]

for safety reasons you can't just hook up a Multimeter to a high voltage battery pack, you essentially need a car battery to turn on this battery

[Gregski]

that's why we remove the lid and bypass the Pre Charge Circuit which contains contactors that otherwise have to be powered up, but this being a German product it ain't all that easy without fandangling with the BMS first I think, so forget that

not bad, that's 346 out of 351 vultures

[Gregski]

I did the same to only one of the six cell modules that are inside that battery pack

57.7 out of 58.5 that's pretty darn good

[Gregski]

I also took the opportunity to weigh one of them, and it came in at 27.7 pounds

so six of them only weigh 166 lbs, so if I double that it will be 332 pounds

anybody know what a fully dressed Small Block Chevy weighs for a stare and compare?

I’m seeing weights from 530-575 pounds.

thanks so that covers three of these packs which adds up to 498 pounds.

I am thinking we could add another 100 pound allowance for a full 16 gallon fuel tank full of gasoline (16 gallons x 6 lbs = 96 pounds) plus 10 lbs for 6 quarts of oil, plus the weight of the exhaust system and I think we are breaking even, even with four battery packs at 665 pounds.

Think it is cool what you are doing. Electric performance and torque is real.
None the less I would never own an electric or do a conversion myself except for a local driver.
Curious if you know what the motor/trans weighs. My aluminum block LSA 6.2 with 6l90 is in 700lb range. The 31 gallon tank I am installing full is around 200lbs. 31 gallons should allow over 400 miles range as long as I keep my foot out of it. What is the range you are expecting?

in this video we take a peak inside the BMW 530e plug in hybrid, high voltage battery pack

BMW 530e Plug In Hybrid HV Battery Pack

Nice video. I did not realize the batteries were in series but I suppose that makes sense to get the higher potential. What is the voltage and variance that the motors are rated for?

the stock Lexus GS450h (the car my motors came from) hybrid battery pack was only something like 288 volts, but that car used a booster converter to up it to as high as 650 volts (to push lower amps) Rated for a combined 250kW output, meaning using gasoline powered engine plus only the single electric motor in the transmission (more on this later) that's 375 horse power.

the pack I am using is from a different plug in hybrid car a BMW 530e which had a 350 volt battery pack. Based on the world's #1 best selling electric car, the Tesla Model 3 and the world's #2 best selling electric car the Nissan Leaf that's all we need as they both run 350 volt packs. It's what I call a full voltage pack. Of course they have a much larger fuel tank capacity if you will than my little 9.1 kWh one.

hope that answers your question

Yes mostly. Im just thinking way ahead. Bumping up current vs voltage, two packs in series/parallel vs strictly series.

yes I plan on running possibly four packs in parallel for a total of still 351 volts but quadrupling the kilo watt hours from 9.1 to 36.4 kWh

of course you are talking about power and I am focusing on capacity, I get that

but the thought of doubling the voltage to over 700 volts did enter my mind if for nothing else a shot down a drag strip [Note To Self: upgrade front drum brakes to disc, lol]

[layinrocker65]

What range will you get with 4 packs?

hopefully at least 100 miles

thought you guys might enjoy this video of Jerry installing the same electric Tesla brake booster I am about to use in my EV Conversion in his 1995 electric Hummer

I got a chance to completely disassembly my BMW 530e high voltage battery pack and would like to share a video with you

BMW 530e HV Battery Pack Teardown

[Gregski]

those pics are on top of a 2 foot by 4 foot piece of plywood for a size reference, looks like I can fit 9 batteries in that space

[Gregski]

it was nice of these plastic pliers to show up right after I shot the last battery video, cause you know, safety third

[Gregski]

yeah, it's winter and I am procrastinating, but when these brand new German (pronounced: "Expensive") BMW high voltage battery cables showed up, I decided to treat 'em right

[Gregski]

they got these god forsaken never seen before dingle dangle proprietary connectors on 'em that are made from unobtanium

so they had to be liberated

[Gregski]

Why you ask? well we are trying to connect this German BMW 530e high voltage battery pack to a United Statesian Tesla Model S battery charger so that we can charge it and it's like fitting a square peg in a hole that's round

[Gregski]

so over at our Organic Out Doors Precision High Voltage Battery Cable Modification Facility commonly referred to as the OODPHVBCMF

[Gregski]

now we can provision a much more civilized connector such as this handsome Anderson SB120 in crimson red
