They have sufficient spare capacity to reliably supply future consumers too. The VARTA 12 Volt battery portfolio is ready to support both today’s as well as future electric vehicles. Their construction and behavior as well as their lack of electronics make them a reliable and robust power source. AGM and EFB batteries are far from being obsolete. They ensure that important safety functions such as ABS and ESP are working at all times.
They step in when the high voltage battery fails or switches off, to lock and unlock the car and also serve as an additional power supply to buffer the electrical system. This is where already proven solutions like AGM and EFB play to their strengths. A further aspect of the protection circuitry is that the cell temperature needs to be monitored to detect and avoid critical malfunctions. Additionally, they need to have the voltage maintained within safe limits, making a special protection circuitry mandatory. Lithium-ion cells need protection from being overcharged and deep discharge. This can vary slightly, depending on the concentration of the electrolyte in. However, they are not as inherently robust as other rechargeable technologies and require continuous monitoring. The charge of a conventional 12-volt automotive battery is actually 12.6 volts. Lithium-ion batteries are considered the successor for lead-acid technology when it comes to the drivetrain of electric or hybrid electric vehicles. VARTA AGM and EFB batteries have proven their reliability in this regard for years, making them the perfect companion in supporting the 12 Volt electrical system of electric or hybrid electric vehicles. This in turn increases the need for a reliable, high-performance power supply. Thats partly because every vehicle needs one, even those newfangled electric vehicles, which use dependable 12-volt systems to power lights, ventilation fans, radios (or Apple CarPlay) and so on. The same goes for the majority of the car’s monitoring functions which are also operated by automatic control systems.

Alongside the high voltage lithium-ion traction battery you might find a second one: A 12 Volt battery acting as a second power source to ensure the uninterrupted function of safety critical systems, in case of a traction battery failure, but also key off-loads like the central locking system.Ĭar drivers today find that more and more comfort and safety features like lane assist, front assist or the proactive occupant protection are handled by onboard smart systems. Have you ever wondered what happens when the lithium-ion battery in a modern electric or hybrid electric vehicle stops working? Look under the bonnet and you will find your answer.

However, AGM Battery products are designed to be less affected by the cold, so browse our range of batteries today.The role of lead acid batteries in electric vehicles This portable automotive battery charger has three modes, making it easy to charge, maintain or jump start 12 volt batteries.
This is why it takes longer to start your car in cold weather. If the temperature drops to zero degrees, the amount of voltage that’s produced by a 12-volt battery could be as low as 7 amps. There are several factors that can impact the amount of voltage that your battery produces, including the temperature. The specific voltage of the current your battery produces varies
So, despite the fact that most car batteries are only 12 volts, they are capable of generating a current that’s around 180 times as powerful as what’s needed to power a 40 watt light bulb. Wattage is the voltage multiplied by the amperage, which gives you an idea of how powerful the electric current is. Amperage can be thought of as the volume of electricity that’s generated, but voltage can be thought of as the “pressure” of the electricity. Voltage is not the same as amperageĮven though most car batteries are only 6 or 12 volts, a 12-volt battery can produce as much as 600 amps. As a result, they typically only produce 6.3 volts of electricity when they are fully charged. Six-volt batteries only have three cells. Your battery is considered to be discharged when each cell holds 1.239 volts or less. However, the amount of electricity that’s produced will decrease as the battery is discharged. Here’s what you need to know about battery voltages: 12-volt batteries have six cellsĪ 12-volt battery has six cells, which produce 12.6 volts of electricity when the battery is fully charged. Small differences in the voltage of your battery can make a large difference when it comes to your car’s performance. Most vehicles are designed to run with a 12-volt battery, but it is often possible to get the same voltage with two six-volt batteries. If you’re getting a new battery for your car, truck, RV, ATV, or any other vehicle, you may be wondering why most vehicle batteries are either 12 or 6 volts.
