Electric vehicles operate differently from traditional petrol or diesel cars, but they can still experience battery-related issues that require jump starting. However, it's crucial to understand exactly what you're jump starting and the safety implications involved.
Unlike conventional vehicles with a single lead-acid battery, electric cars have a sophisticated dual-battery system. This complexity means that whilst jump starting is possible, the process requires careful attention to safety procedures and manufacturer guidelines. Understanding the disadvantages of electric cars can help drivers prepare for situations like battery failure, though modern electric vehicles are increasingly reliable.
For employees accessing electric vehicles through company electric car schemes, comprehensive breakdown cover is typically included as standard, making professional assistance readily available for any battery-related issues.
Can You Jump Start an Electric Car?
Yes, you can jump start an electric car, but with important limitations. You can only jump start the 12-volt auxiliary battery in an electric vehicle – never attempt to jump start the high-voltage main battery pack.
The 12-volt system in an EV serves the same function as in conventional cars: powering basic electronics, lights, infotainment systems, and enabling the vehicle to start its primary systems. When this 12-volt battery fails, your electric car becomes inoperable, even if the main battery has charge.
Crucially, jump starting the 12-volt battery will not add range to your electric vehicle if the main battery is completely depleted. However, a dead 12-volt battery can prevent the main battery from charging, making jump starting the first step towards getting your EV operational again.
For drivers participating in an electric car salary sacrifice scheme, understanding this procedure is valuable, though most comprehensive packages include breakdown assistance that covers 12-volt battery failures, eliminating the need for DIY jump-starting in most situations.
What Makes Electric Car Batteries Different?
Electric vehicles employ a sophisticated dual-battery architecture that differs significantly from conventional petrol or diesel cars. Understanding how electric cars work helps clarify why jump starting procedures differ from traditional vehicles.
Why Do Electric Cars Have Two Batteries?
Unlike conventional cars with a single battery, electric vehicles feature two distinct battery systems:
High-voltage battery pack (typically 300-800 volts): Powers the electric motor and provides the vehicle's driving range. This is the main battery that determines how far your EV can travel on a single charge.
12-volt auxiliary battery: Powers conventional vehicle systems like lights, locks, infotainment, and the computer systems that control charging. This smaller battery operates independently from the main pack and is essential for basic vehicle functions.
These two systems operate independently, with the 12-volt battery drawing power from the main battery pack during normal operation. This architecture is standard across popular models available through salary sacrifice schemes, including Tesla vehicles, BMW electric cars, and Nissan EVs.
What Does the 12-Volt Battery Do in an EV?
The 12-volt battery in an electric car performs several critical functions that many drivers don't immediately appreciate:
Initiates the vehicle's startup sequence – Without this, your EV won't "wake up" even if the main battery is fully charged
Powers lights, windscreen wipers, and climate control when stationary
Operates door locks and security systems – Essential for basic access to your vehicle
Runs infotainment and navigation systems – Your touchscreen and connectivity depend on this battery
Controls the charging port and related systems – Ironically, a dead 12V battery can prevent you from charging your main battery
Maintains memory settings for seats, mirrors, and radio presets
Without a functioning 12-volt battery, these essential systems cannot operate, rendering the vehicle immobile regardless of the main battery's charge level. This is particularly important for drivers who access EVs through workplace salary sacrifice schemes, as understanding these basics helps ensure smooth operation throughout your lease term.
What Causes EV 12V Battery Failure?
Several factors can cause the 12-volt battery in an electric vehicle to fail prematurely:
Extended storage: Leaving an EV unused for more than 30 days without charging can drain the 12V battery. This is particularly relevant for employees with company electric car schemes who may leave vehicles unused during extended holidays or work-from-home periods.
Complete main battery depletion: When the main battery reaches zero percent and remains there for extended periods, the 12V battery cannot recharge itself, leading to failure.
Age-related degradation: 12-volt batteries typically last 3-5 years in electric vehicles, similar to conventional cars. Regular electric car maintenance and servicing can help identify battery issues before they cause failure.
Extreme temperatures: Both very hot and very cold conditions accelerate battery degradation. Understanding how electric cars perform in winter helps drivers take preventive measures to protect both battery systems.
Parasitic drain: Faulty systems continuing to draw power when the vehicle is off can slowly deplete the 12V battery over time.
Manufacturing defects: Some 12-volt batteries may fail prematurely due to manufacturing issues, though this is relatively rare with modern EVs available through reputable salary sacrifice providers.
Regular EV servicing can help prevent many of these issues, and most comprehensive salary sacrifice packages include maintenance that covers battery health checks.
Can You Use an Electric Car to Jump Start Another Vehicle?
No, you should not use an electric vehicle to jump start another car. Most manufacturers explicitly advise against this practice, and attempting to do so may void your warranty and cause significant damage to your EV's electrical systems.
The 12-volt battery in an electric vehicle isn't designed to provide the high current surge required to start an internal combustion engine. Unlike conventional car batteries that work alongside an alternator to provide substantial starting power, EV auxiliary batteries serve a different purpose and lack the necessary output capacity.
Why Can't EVs Jump Start Other Cars? Technical Limitations Explained
Electric vehicle 12-volt systems have several technical constraints that make them unsuitable for jump starting other vehicles:
Lower current output: EV 12-volt batteries cannot deliver the 300-600 amps typically required to crank a petrol or diesel engine. They're designed for steady, low-current applications rather than high-current surges.
Different charging profile: EV auxiliary batteries operate on a fundamentally different electrical architecture. They receive power from the main battery through a DC-to-DC converter, rather than from an alternator as in conventional vehicles.
Integrated management systems: Modern EVs, including popular salary sacrifice models, monitor 12-volt battery usage constantly. Unexpected high-current draws can trigger protective shutdowns, potentially leaving both vehicles stranded.
This is particularly important for drivers who've accessed EVs through workplace salary sacrifice schemes, as warranty violations could result in significant repair costs not covered by your employer or the scheme provider.
Will Jump Starting Void My Electric Car Warranty?
Using your electric car to jump start another vehicle can have serious warranty implications:
Explicit manufacturer warnings: Tesla, for example, states in their owner's manual: "Do not use the battery as a stationary power source. Doing so voids the warranty." Similar warnings appear across BMW, Volkswagen, and Nissan electric vehicles.
Electrical system damage: Attempting to provide high-current output can damage the DC-to-DC converter and battery management systems, with repair costs potentially reaching thousands of pounds.
Insurance implications: Some electric car insurance policies may not cover damage caused by using your vehicle to assist other motorists. Understanding salary sacrifice car insurance is crucial for employees accessing EVs through workplace schemes.
Scheme provider considerations: For drivers with company electric car schemes, using the vehicle contrary to manufacturer guidelines could affect your agreement and potentially result in charges for repairs.
What Damage Can Occur When Jump Starting From an EV?
The risks of using an EV to jump start another car include:
12-volt battery damage: Excessive current draw can permanently damage the auxiliary battery, requiring replacement at costs of £150-300.
DC-to-DC converter failure: This critical component converts high-voltage power to 12-volt power and can be expensive to replace, with repair bills potentially exceeding £1,000.
Software complications: Modern EVs rely on complex software systems that can malfunction when subjected to unexpected electrical loads, requiring professional diagnosis and reprogramming.
Fuse damage: Protective fuses may blow, requiring professional diagnosis and repair that could leave you without a vehicle for several days.
For these reasons, carrying a portable jump starter in your electric vehicle provides a safer alternative for helping other motorists without risking damage to your own vehicle or voiding your warranty.
