Anyone have experience of Jump Starters on 2022 PHEV

[George22]

Hi, just seen an ad for Ring Ultraboost jump starters, £75 ish. 
 

I frequently visit my daughter in London (from Devon) and may leave the car standing around not used for two weeks over the Christmas period.

I’m reasonably sure it will be ok after the 200 mile journey but just thought maybe I should have some extra insurance (with the booster) as well as already having car breakdown cover. 

Any advice or experiences appreciated, thanks.

So, presumably you are looking at the 500A version (on Amazon)? That would be more than enough to do the job. I carry a Noco Boost Sport GB20 that is equivalent at 500A.

I note that the 1000A version of the Ring is available for less than the 500A version so that might be an amusing alternative. 🙂

If you're taking your '22 RAV into London and will be leaving it anywhere I would invest in a StopLock Pro or Milenco steering wheel lock. Better safe than sorry.

Yes thanks. I’ve got a StopLock Pro and have had the Toyota theft protection plates fitted, also the car has lots of warning stickers 🤞
 

I also sleep with one eye open 👀 😂

I thought the PHEV doesn't suffer from the CANbus attack problem?

I got a NOCO. Big one. Can't recall model but I also wanted to start the wife's car. 

Had a spell with the 12V Battery going flat constantly even after just a day or two. That was the DCM module software, not shutting the unit down after turning off the car. Update fixed it. 

I've left the car (my last 2021 PHEV) for periods of up to about 4 weeks. Started first time. But I still keep the NOCO in the glove box. Just in case. More likely though I'd be helping someone else out with it.

I like the NOCO unit I got because it's also a massive powerbank with USB charging ports and a light.

You're right, it doesn't. But... would you park your car in London and trust that the scrotes know the difference between a vulnerable 2022 RAV4 and a secure one? Or would you just fit a visible deterrent?

That's rhetorical because I know you do anyway and, so does George, just thought it was worth mentioning.

Comment was in reference to having the plates fitted when the subject of the post contains the word PHEV. Hence my surprise and clarification question.

Curiosity question - can anyone tell me why these Battery jumpstatter packs have significantly higher Amperages than the equivalent 12v batteries they're trying to jumpstart? (and thus by extension, how one judges what Amperage one needs for the size of one's own engine, ie is the 500A perfectly suitable, or is there any benefit to opting for a 1000A unit?)

 

Noco appear to offer jumpstarter units up to 4250A, whereas even the largest Battery I could find browsing the HGV direct website (picked randomly from Google search, no prev experience) is 1400A. What's the point?

Well, the car Battery industry is (or was) primarily focused on pure ICE vehicles with starter motors. The role of the starter motor Battery is to run the starter motor fast enough and long enough for the engine to catch and start running the alternator as the source of electrical power. Starter motors are rated between about 1kW and 6kW so would require between 85A and 500A to run continuously but the initial draw is considerably higher - maybe 300A to 1000A.

So, for example, my RAV 4.4 diesel was equipped with a 100 Ah Battery (capacity) capable of delivering 830 CCA (cold cranking amps). If I were looking for a Noco Boost to start that car I'd go for a GB40 at 1000A or a GB50 at 1500A. And if you are looking for a jump starter capable of 'jumping' the average ICE as well as a hybrid then those would be the right sort of size.

But we now have hybrids / EVs and all that is required in order to start the car is enough power to prime the braking system - not a lot really - 10s of amps will be enough, certainly less than 100A and only for a few seconds. So, I went for the GB20 at 500A - way overkill for our cars and probably enough to have a decent go at starting the average ICE should it ever be asked to.

So, what's the point? Having a greater capacity / current delivery will start much larger engines once or more modest engines many times before the jump start pack need recharging. And the other point, bigger numbers sell better - after all we all have to have the biggest! 😉

High power circuit. In simple terms you can store and dump a lot of energy in a short space of time. High power in other words. If voltage is fixed and Power = I x V then what changes is the current. Current must be high if power is high where also power = energy / time.

For example, a capacitor circuit or an inductive circuit can be configured to deliver a very high voltage or high current, or, and ultimately, high energy in a short space of time this high power. Voltage is easily up or down converted btw. Both DC and AC.
