250 Hybrid Battery Utility (1 Viewer)

Does the hybrid battery in the 250 offer any type of overlanding utility or is it for high-voltage propulsion only?

The thread linked below has some thoughts about this from others

Running 12V fridge/etc

Lots of great posts on here so far with insights/comments/specs on the new LC250/LX550/4R. One topic I haven't seen discussed is whether the hybrid battery can be used for anything besides running the hybrid motor. Since the LC250 comes stock with a good sized "second" battery, how does that...

20+ combined mpg on the truck, 2.4 KW (20 amps) of AC power, and 150 ft-lb of electric torque at idle.

Based on how our RX 350h behaves I anticipate the 250 will have very good low speed efficiency and driveability.

The 2.4KW is enough to use an induction cook element, make coffee, use an AC powered compressor and charge portable tools.

I should have been more specific, was focusing on electrical power for camping uses.

Thanks. So the answer is 'no'. That's unfortunate, especially considering the target audience (overlanders).

20 amps vs 3 amps is a pretty big jump in capability and can power a lot of stuff for camping.

The answer may be "no" from the factory (I'm not sure anyone is certain right now), but surely the aftermarket can somehow make use of it. Modifying the rear inverter to be full time on (and not just ignition on) could be as simple as modifying a relay. Or maybe someone can come up with a software fix. Who knows, and who knows whether doing so would have serious consequences with regard to vehicle performance once it's turned back on.

Maybe I read it wrong, but if it only works with the ignition on then it seems useless for camping and would still require some type of house battery solution.

I haven't reread the thread, but I believe it works with the ignition off until the battery would drain itself beyond recovery, then the engine kicks on. Besides, turning on your vehicle for it's power does not make it useless for camping. It isn't a rolling Goal Zero battery bank. However it is an objective upgrade in capability.

Hopefully there will be some method that doesn't jeopardize battery warranty. Huge untapped overland potential.

From the other thread, it was said that the 2400W inverter was the only power tap from the hybrid pack and that was only enabled with ignition set to accessory.

Ah sorry. I was talking about the engine itself being off during accessory mode.

From the linked thread, the traction battery is 1.87kWh. If it was available As a second battery for camp use, it would be very roughly the equivalent of this Redarc.

Alpha150 12V 150Ah Lithium Battery

Extra-long lifespan and huge discharge rate make this the ultimate lithium battery.

I agree with the 1.87kwh number being the published value. However, that's a lot of space in the rear being taken up for such a small battery pack. The 4xe in comparison has ~ 37kwh. Though it is a PIH and has a battery-only range of something like 25 miles.

Makes one wonder how long the battery assist feature can sustain? What is the use map like for the hybrid assist in the 250? Is it for peak demand only or does it actually supplement in normal drive cycles?
