Electric vehicles are increasingly becoming a mainstream choice for environmentally conscious drivers, offering a range of benefits from zero emissions to lower operating costs. But like any vehicle, EVs are not immune to issues that can leave drivers stranded, especially when the battery starts to falter. A common question among new EV owners is whether these vehicles can be jump-started in the same way as traditional petrol-powered cars. Understanding how EVs work, particularly their battery systems, is key to answering this question.
Understanding the EV Battery System
Internal combustion engine (ICE) vehicles rely on a 12-volt lead-acid battery to start the engine. Whereas, different types of EV batteries, mainly lithium-ion, are used to power the electric motor. This high-voltage battery is typically much larger and more powerful, often ranging from 200 to 400 volts. However, the primary purpose of the 12-volt battery in an EV is similar to that in a petrol car. It powers electrical components such as lights, infotainment systems and the car’s onboard computers.
When an EV fails to start or has trouble powering up, it is typically due to one of two issues:
- The 12-volt battery has drained.
- The main high-voltage battery is low or depleted (though this is a rarer occurrence due to the long range of modern EVs).
It is essential to identify which of these two components is the source of the problem before attempting any jump-start procedures.
How to Jumpstart an EV
It is possible to jumpstart an electric car’s 12-volt battery the same way as a petrol vehicle. A set of jumper cables and another vehicle with a functioning 12-volt battery can be used to transfer power and get the vehicle’s electrical systems back online. Many EVs also come with dedicated jump-start points under the hood or in the trunk, designed to make the process as straightforward as possible. That said, individuals can jumpstart the car battery in an EV using the conventional method.
However, unlike ICE vehicles, EVs should never have their high-voltage main battery jump-started. Attempting to jump-start or charge the high-voltage battery could lead to damage or even pose a safety hazard due to the risks associated with handling high-voltage systems. Additionally, modern EVs are equipped with complex electronics and safety features that prevent the high-voltage system from being inadvertently tampered with.
Can a Dead Main Battery Be Revived?
If the main high-voltage battery is entirely dead or depleted, jump-starting it with a traditional vehicle will not work. A professional technician or EV roadside assistance service will likely be needed in such a case. These professionals are equipped with the appropriate tools to assess and manage the situation safely. Moreover, some EVs have a Turtle Mode, which is a low-power state that allows the vehicle to be driven to a charging station or service centre even when the battery is running low.
FAQs
Can you jumpstart an electric vehicle like a normal car?
No, an EV cannot be jump-started like a normal car. Only the 12-volt battery can be jump-started, not the high-voltage main battery.
Which EV battery can be jump-started?
Only the 12-volt auxiliary battery in an EV can be jump-started.
Can you use an EV to jumpstart another car?
No, most EVs cannot be used to jump-start another car. They lack the necessary 12-volt power output or the appropriate jumper connection.
This is how to jumpstart an EV and the things to avoid while doing so. While EVs can be jump-started similarly to traditional vehicles if the 12-volt battery is the issue, jump-starting the high-voltage main battery is not an option. A professional service should be contacted in the event of a dead main battery.
The evolution of car batteries has seen these components become more advanced with time. Owners should know the EV battery drainage factors to take better care of their vehicles.
Modern EVs come with a range of features that help with the upkeep of the battery and the vehicle’s overall performance. Discerning buyers can find many electric cars for sale in the UAE, available with a plethora of safety and performance features.
