Backyard mods to hybrids and EVs - perhaps it’s the next big thing in aftermarket tuning. What could possibly go wrong?

It’s opening the window to the next big thing in well-intentioned backyard disasters. "Tell me please, am I dreaming, or would it not be feasible, to convert a "soft hybrid" or just hybrid car to a full plug-in hybrid, by adding another battery and appropriate connections? Series or parallel, wouldn't that at least double autonomy and offer the option of mains charge? Or would it end up costing as much as a full EV?" - John You’re talking about messing with a great deal of stored energy, and the potential for disaster is extremely high. It’s a fascinating question, though, because as hybrids and EVs become more mainstream, I suspect we will see an explosion in aftermarket modifications for the electrical side of these vehicles. But seeing as there’s no convenient, spare space in the engine bay or the sub-floor space, the additional battery you fit would have to be installed in the boot, where it would be vulnerable to crash damage (which poses an extreme fire risk). You’d have to include temperature management for both charging and discharging. If you don’t do this, there’s the risk of killing the battery early, and also fire or explosion. So: Cooling system: not optional. And, obviously, liquid cooling is the way to do it - it’s like, an order of magnitude more efficient than air cooling. Then there’s the high-voltage wiring and all the technical caveats for safe installation that this imposes, and the sundry crap that you need. I suppose you could find a wrecked plug-in hybrid - whatever, and salvage many of the bits. To put this in perspective, a 36-volt, 5 amp-hour battery for Ryobi yard-type electrical power tools costs $299 retail at Bunnings. That’s 180 watt-hours of electrical energy, or 0.18 kWh (kilowatt hours). Hold that thought. A Hyundai Ioniq hybrid has 1.56 kWh of battery storage on board. (That’s about nine of these Ryobi batteries, equivalent.) I’m using the Ioniq as an example because the factory hybrid and plug-in hybrid executions are directly comparable - so you can see what a major carmaker has done in terms of each execution. The plug-in hybrid Ioniq (same car - just plug-in) has 8.9 kWh of battery. (That’s about 50 of these Ryobi batteries.) Five and a half times more battery capacity. Let’s say you intended - conservatively - to add 5 kWh of electrical storage to your standard hybrid ‘donor’ car. You have to find a spot for 30 of these batteries, near enough. At the same price per kilowatt-hour as the Ryobi battery that’s about (ballpark) 30 times the energy, so 30 times the price, or about $9000. Jaycar Electronics here in Shitsville will sell you 18650-type Li-ion rechargeable battery cells (they’re unprotected cells) for $12.45 each as a bulk buy. They’re 9.62 Wh batteries. So you’d need 520 of them for 5 kWh - that’s about $6500. And of course you’d need to figure out how to wire them up robustly and protect them against overcharging and discharging, and overheating… Which, in itself, is a serious engineering job. It’s doubtful to me you could do this on a shoestring for less than about $20,000. That’s not including your own time. Bear in mind you can’t do development of this kind well in one hit. At this point it behooves me to point out that it’s cheaper just to buy the plug-in hybrid, which is about $6500 extra in the case of the Ioniq.
