The heart is an important organ that affects the duration of human life. Any technique has the same control element - a motor, and various components help it to carry out this function, one of which is the battery.
Since the modes of transport are divided into three main categories: land, air and water, then each of them has its own subcategory. The review will present batteries for electric vehicles, which, according to buyers, are considered the most efficient and reliable for 2024.
Content
A battery is equipment that stores and uses electricity without a network connection. For vehicles of this series, traction devices are used. Their advantage over other types is the ability to operate for a long time at constant loads (without recharging). In this regard, their scope of application is multifaceted.
Working principle: oxidized lead in a solution of sulfuric acid and water settles on the positive plate during battery discharge, while sulfur dioxide is recovered on the negative side. Charging the battery is the reverse process.
On a note! In the process of replenishing food in the electrolyte, the content of sulfuric acid decreases, and the volume of water increases.
The device has a housing, a +/- electrode and an output, a separator, an external down conductor for a block of plates of the same name (a baffle), support prisms, a cover, a screw plug, and a connecting bridge.
Description of parts: frame - fire-resistant material, plates - metal gratings. Pole elements (filling the gratings): pressed powder - in a plate with a minus sign, sulfur dioxide - in a plate with a + sign.
In the "grooves" between the plates, there are microporous elements made of ebonite / revertex (both made of rubber), which disconnect the different poles of the electrodes to avoid short circuits (caused by vibrations of the engine or the entire vehicle).
There are several types of batteries for electric vehicles: starting, buffer and traction.
The starter is suitable only for starting the engine, it is at the moment of starting that the main amount of energy is given, and its replenishment - while driving.
In traction units, the opposite happens, they are designed for long-term and stable energy supply (they work everywhere).
Buffer batteries are efficient at low discharges. They are 20% less than traction ones, respectively, and cheaper, but their service life is practically 2 times less. They are mainly used in test equipment and medical control systems.
On a note! In buffered mode, AGM lead acid batteries (about 12 years old) work fine and slightly shorter when used in deep charge / discharge mode.
Before you understand which is the best to buy a battery for electric vehicles, you need to know what devices exist. Traction devices are divided into classes. Each of them has its own marking (shown in the table below).
It is interesting! If we take the percentage of substances in a calcium battery, then the main element in it is not more than 0.1% of the entire plate (meaning weight). Therefore, it would be better to call the product "lead-calcium", but in ordinary life, a simple formulation was fixed.
In the alkaline storage, the role of the electrolyte is played by caustic sodium or potassium. In addition, the composition contains graphite, which has a beneficial effect on conductivity, and various impurities normalize the working capacity and stability of the apparatus.
Note! The “-” element includes a metallic alloy of cadmium, nickel and a specific powder. In each case, the ratio of the components is unique. And lithium monohydrate, which is part of the electrolyte, is responsible for the durability of the unit.
The hybrid machine is designed for the car. Includes: low antimony anode and calcium cathode. In comparison with calcium devices, it has an improved technical base.

In addition to marking, you need to know the size of the device, be able to decipher codes. Specialists often help with this. The buyer will only need to decide which company is better to buy the product.
Each buyer sets himself the task of how to choose a battery so that it will last for a long time. Therefore, the main indicator that users of electric transport pay attention to when choosing a battery is its resource.
The most reliable means the most expensive, and in fact it is almost always the same, as many buyers claim. If we consider batteries for passenger cars (electric), then the average service life is 8-10 years, but there is no exact confirmation of this statistics, since there are very few electric cars in long-term operation, and the popularity of models of such transport is just beginning to "grow its career." ... Most manufacturers set a service life of up to 5-8 years, well in advance of failure, so that the owner can replace the battery in time.
In many batteries, the capacity gradually decreases, so after several years of operation, there is a decrease in the electric vehicle's power reserve from the initial value to 70-80%.
On a note! A lithium-ion battery degrades its performance regardless of charge / discharge cycles, while most other devices degrade with each charge. As for the rest of the batteries, it all depends on the conditions of use, which are significantly influenced by the environment.
When choosing a "hybrid", pay attention to the need for adding water (the last character in the marking): normal (N), low (L), very low (VL), with a regulating valve (VRLA). This indicator indicates the type of service, notifies whether the water level should be monitored, indicates the setting of the current parameters, which is used during recharging.
In terms of power, the calcium and hybrid units are considered the most advanced. They are in great demand among modern motorists.
On a note! Calcium devices are installed only in cars, if they are installed in a boat or boat, they can undergo a deep discharge, which is better to avoid.
As noted earlier, electrolyte is an important component of the battery. Under the influence of low temperatures, it does not freeze (unlike water), but thickens, loses its properties and the battery capacity decreases. To avoid such a situation, various additives are added to the substance.
GEL batteries are the pinnacle of evolution. They do not lose their properties in cold weather (stable) and are immune to overturning due to the jelly-like mass.
An important indicator is the cold cranking current, which is measured in amperes according to a certain method. The main standards include:
Based on modern requirements, popular battery models should use a drive with increased energy consumption without changing the dimensions and weight of the product.
The main representatives of this segment are goods from foreign manufacturers, batteries are very popular with buyers. The peculiarity of the presented goods is their wide application. The cost of the battery depends on the technical base. Top firms:

Selection of a battery for electric transport depends on the multiple charge / discharge cycles with further full charging. For buffer batteries, the thickness of the electrodes, the composition of the active mass and the weight are important.
On a note! Batteries for UPS in cyclic operation are 2-3 times less than specialized traction batteries.
