Also keep in mind that the i3 lacks a traditional 12 volt starter battery. For instance, the HV battery is used to start the REx. Only board electronics and illumination use the 12v system. No matter how pretty the damsel in distress was, I wouldn’t dare offer a jump start.
Honda hybrids employ a traditional 12 volt starter motor because the high-voltage NiMH battery pack could be harmful in colder climates. Even though the battery in our 2000 Honda Insight is a tiny absorbent glass mat (AGM) battery, which shares the same battery design as the i3’s battery but is physically much smaller, it can start an Insight’s engine using a 12 volt starter motor despite almost certainly having a lower capacity and cranking power. Therefore, unless the i3’s 12 volt battery is dying, there is no reason to think that it wouldn’t have enough power to jump start another vehicle.
It can be quite challenging to tell whether an i3’s 12 v battery is dying because the battery never needs to provide the briefly high current required to power an ICE starter motor. A poor i3 12 v. battery could be killed by one jump start attempt. Perhaps the sole early indication of a failing 12 volt battery is the poorly phrased low battery power alert that some i3 users are experiencing. The similar issue affects gasoline-electric hybrid vehicles since their 12 volt batteries infrequently or never power a starting motor.
Because of this, I would only jump start another vehicle with our i3’s 12 volt battery in an emergency, but I would be fairly certain that the jump start would be successful without causing damage to our i3.

Carry a tiny portable battery booster pack if that’s a problem, especially in the cold.
These kinds of statements amaze me. There must be a severe design flaw in the car if it cannot do the straightforward task of charging a 12V battery even though it has a large battery to support the charge.
While the main battery is being charged while the car is operating or turned on, the BMW i3 charges the 12 Volt battery. Most likely, the i4 is the same. A second recharge of the 12v battery when the car is switched off, as well as using 12v to power a portable fridge, etc., are the only things that are missing.
Although I have never experienced a problem with the i3, it is definitely a good idea to have a small battery booster pack so you may assist others without endangering your own vehicle.

Jump starting should be fine because the lead acid battery in many EVs is just a regular automobile starter battery. Usually, the “boosting” battery is only providing a portion of the power needed to bring the weaker “dead” battery beyond a difficult period. For the record, my track car’s main starting battery is a 20ah mobility scooter battery, and it gladly starts a 1.8L gasoline engine.
Instead, if you have time and are concerned about damage, simply jump-start the two vehicles as usual, turn the EV “on,” and allow the EV’s battery charger to charge the ICE battery for 30 minutes. The ICE can then be started normally after disconnecting the EV. This method also works for ICE to ICE leaping, although it requires leaving the booster car idling on the driveway, which is less desirable.
Even if you plan to jump start the dead car “naturally,” letting it charge for even 5 or 10 minutes will greatly minimize the burden placed on the battery of the boosting car, so it’s always a good idea if you have the time.
Can you jump start another vehicle with an EV?
Although it is technically possible, you shouldn’t attempt to jump start a gas-powered car from an electric or hybrid car.
Although the procedure is slightly different from the standard way, it is technically possible for an EV or hybrid to jump-start another vehicle. Normally, it can be done by hooking up both car batteries using a typical set of jumper cables and waiting for the power to switch. The negative clamp on the wires should be connected to a grounding point on the receiving car’s frame rather than to the negative pole of the receiving battery in a typical jump-starting technique between two gasoline engines.
However, you shouldn’t actually do this because it could seriously harm your car.
Why? It appears to be related to how EVs function and what the 12V battery in an EV truly performs. On a gas-powered car, the battery supplies the electric starter with the power it needs to physically move the internal combustion engine quickly enough to ignite.
EVs lack an ignition circuit because there isn’t any actual fuel to ignite, and their 12V batteries don’t have the same spark. That implies that they lack the skills necessary to jump-start the engine of a different vehicle.
An EV’s 12V battery may become overworked if a jump is attempted, which is bad for the battery. Additionally, it may cause problems down the road and possibly harm the car’s DC-to-DC converter by confusing the battery monitoring software.
An electric car’s DC-to-DC converter is a crucial component because it enables the 12V battery to draw power from the larger battery and uses the smaller battery to operate low-voltage components like the doors, lights, and climate control. Your electric vehicle is essentially useless if that converter breaks down.
In fact, this is the reason why many manufacturers expressly warn against using an EV to jump-start a gas-powered car.
In the owner’s guide for the Nissan Leaf (opens in new tab), there is a caution that reads, “Because LEAF lacks the power to start a gasoline engine, it cannot be used as a booster vehicle. The 12-volt battery of the LEAF can, however, be jump-started using a car with a gasoline engine.”
The Tesla Model Shandbook (opens in new tab) warns against using the car to jump-start another vehicle since doing so could harm the Tesla. The owner’s manual also warns that jump-starting a car counts as utilizing it as a stationary power source, which will void your warranty.
You won’t be able to continue doing that for very long. In place of the more typical lead/acid battery, Tesla’s 2021 Model S and Model X vehicles come equipped with a proprietary 12V lithium-ion battery. The Model 3 and Model Ys are also predicted to undergo this upgrade in 2022.
As long as the electric vehicles are using standard 12V batteries, Nissan, Tesla, and many others affirm that receiving a boost from a gas engine is completely safe. Therefore, don’t be deterred by the fact that your EV cannot be utilized as a power source.
How can a BMW jump start another vehicle?
Connect one of the red clamps to the positive (red) terminal on your own BMW vehicle. Connect the other red clamp to the helping vehicle’s positive (red) terminal. Connect the negative (black) terminal of the assistance vehicle to the black clamp. The other black clip should be fastened to any bare metal surface on your car.
Can a BMW jump-start a vehicle?
Following the positioning of both vehicles, here is how to jumpstart a BMW: Determine the positive and negative terminals on each battery by removing the covers. Connect the first red clamp to the red (positive/+) connector on your BMW car. Connect the second red clamp to the functional battery’s positive terminal.
Can you use the trunk to jump start a BMW?
The fact that jumpstarting procedures for a BMW are remarkably similar to those for any other brand surprises a lot of Greenwich drivers. Although many BMW batteries are located in the trunk, restart connectors are located underneath the hood.

Can a Tesla be used to kickstart a vehicle?
In conclusion, it is not a good idea to use a Tesla vehicle to jump start another vehicle. The low voltage of a Tesla battery as opposed to the high voltage of a combustion engine is the cause of this. It may result in a dead battery if you attempt to jump start one using a Tesla.
Regardless of whether they are a neighbor or someone you see on the side of the road, you could still want to assist someone in starting their car. Keep a lithium-ion jump starter kit that serves as a traditional battery in your trunk instead of putting your EV’s battery at risk.
