That 12-volt battery will power things like lights, the entertainment system and wipers, but also needs to be powered-up in order to get an the lithium-ion battery to charge, too. but with an electric or plug-in hybrid, it may require some searching. But it can be a bit trickier - that's because the location of the battery is generally easy to find in a petrol or diesel car. It's no different jump-starting either an electric car or a plug-in hybrid as it is to a conventional diesel or petrol car. One is the main battery that powers the car itself, but there's also a smaller 12v battery that powers the car's electrical components, just as you'd find in a conventional petrol or diesel car. You may not be aware, but electric and hybrids do in fact have two batteries. Yo may find that the lithium-ion batteries may not be able to be recharged unless the vehicle is jump-started via the 12-volt system, which gets the electronics to kick-in. You will need to jump start an electric car if its batteries are entirely drained.

How to prevent catalytic converter theft. Does my car have a DPF diesel particulate filter?. Just buy a jump pack, keep it charged up and if you ever end up with a flat battery, you can be on the road in a matter of minutes, rather than having to wait for the aid of another car and driver. Using a small jump pack removes all the dangers such as accidentally clashing leads and so on. With the advent of lithium-ion jump packs, there’s no need to mess with two cars, two batteries and two leads. Realistically, the days of needing to use a pair of jump leads and another car are well behind us. How long does it take to jump start a car Which method should I use? Once running, remove the leads – positive first (+) then negative (-). Press this, then try to start the car again If it doesn’t start, many jump packs are fitted with a ‘boost’ button, which delivers a stronger jolt of current. 
Connect the supplied leads to the battery terminals, being sure to connect the negative (-) first. Jump starting with a lithium-ion jump pack: When the sick car has started, remove the leads by reversing the process. No luck? Leave it for a few minutes and try again. The sick car should now start when you turn the key. Build its engine revs to 2500rpm to produce a strong current. Start the healthy car's battery and let it run for a minute. This could be on the engine block itself, a piece of unpainted metal or an officially marked earthing point. It is safer to connect it to an earthing point under the engine bay. The latest advice is to NOT connect the negative lead to the negative battery terminal of the old battery as this creates a fire risk. 
Connect the negative (black) lead to the negative (-) terminal on the working battery. Connect the other end of the positive lead to the positive terminal on the dead battery. Connect the positive, or live (red) jump lead to the working battery's positive (+, or red) terminal. First off, ensure both cars are off with handbrakes on, and parked closely together. 'How to jump-start a car with leads?' can be explained in ten easy steps: Jump packs used to be relatively unwieldy devices, but lithium-ion technology means they are now highly portable.

Jump packs are portable batteries that you can charge at home and then hook up to your car battery to get its engine spinning. Your second option is to use the car salesperson's friend – the jump pack.
The downside of this system is you need another healthy car and someone with the time and will to help you out – not things you can always guarantee to find. Once the engine's sparked – and assuming there's nothing else wrong (like a faulty alternator) – from there the car can charge its own battery.
Essentially, you're sending the power from a healthy car with a charged battery to the other car with a flat battery – the slug of electricity is enough to crank the sick car's engine and, with a few turns, it spins into life. Thirty years ago it was common to see two cars with their bonnets open, with a pair of cables connecting their batteries – this was jump-starting.
