Welcome, Jalopnik readers, to one thing fully completely different: a Tesla article that has nothing to do with controversial frontman Elon Musk and his position within the Trump Administration or DOGE. As a substitute, we’ll tackle the burning query of what occurs if a Tesla proprietor encounters an inner combustion engine (ICE) car with a useless battery? The temptation could also be sturdy to depart that polluting, earth-wrecking heap stranded by the aspect of the street. However assuming that you are a good particular person and really wish to assist a fellow motorist out of a jam, are you able to and must you?
To be clear, Tesla strictly forbids jump-starting different automobiles, ICE or in any other case. In truth, the house owners guide for a Mannequin 3 could not be clearer. It particularly states, “Mannequin 3 can’t be used to jumpstart one other car. Doing so may end up in harm.” In case you try and jumpstart an ICE car together with your Tesla, Jalopnik will certainly not be answerable for any monetary destruction that ensues. With these disclaimers out of the way in which, sure, you possibly can most likely jumpstart a gasoline-powered automobile with a Tesla. However did we point out that you just should not?
Bounce-starting will most likely work, however it’s dangerous
Apart from the high-voltage traction battery that powers the drive wheels, many Teslas even have a traditional 12-volt battery like common vehicles beneath the hood. There’s additionally a DC/DC converter on board that enables auxiliary methods like lighting and audio to faucet into the massive lithium-ion traction battery. The chance begins with utilizing a Tesla’s 12-volt battery to jumpstart a fuel automobile as a result of the high-amperage load from the opposite car’s starter motor is able to stressing the small-ish Tesla battery.
Nevertheless, wrecking a Tesla’s 12-volt battery is nothing in comparison with what occurs for those who harm the DC/DC converter within the strategy of jump-starting. Granted, the DC/DC converter is rated for a wholesome 200 amps, however there’s at all times a small threat of a sudden surge that bricks this dear element and sends you to the dealership on a tow truck for an costly restore. That is significantly true in chilly climate, when an ICE car might require extra cranking amps to get going. Ditto for bigger engines like V8s or diesels that require increased cranking amps.
This is what Tesla house owners can safely do to assist
So what must you do if you wish to safely assist a fuel car driver with a useless battery? This subsequent suggestion is not endorsed by Tesla both, however some house owners point out that it is a lot much less dangerous to let the ICE car’s battery cost from Tesla’s 12-volt battery for some time, like 10 to fifteen minutes. When the fuel automobile is able to try beginning, disconnect the jumper cables (used as charging leads) from the Tesla first.
Now can be a very good time to say that some latest Tesla fashions are transferring away from common 12-volt automobile batteries altogether in favor of a 16-volt lithium-ion auxiliary battery. When you’ve got the brand new 16-volt structure otherwise you’re undecided which kind you have got, positively don’t try to hook up with an ICE car. On one Tesla discussion board, some significantly good-hearted EV house owners point out carrying a small, cheap lithium-ion jumpstart pack to help stranded fuel automobile drivers with out risking harm to their very own whips. Maybe Tesla house owners aren’t so unhealthy, in spite of everything?
