The heart is an important organ that affects the duration of human life. Any technique has the same control organ - the motor, and various components help it to carry out this function, one of which is the battery.
Since modes of transport are divided into three main categories: land, air and water, 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 2022.
Content
A battery is an equipment that stores and uses electricity without a network connection. Traction devices are used for vehicles of this series. Their advantage over other types is the possibility of long-term operation at constant loads (without recharging). In this regard, their scope is multifaceted.
How it works: Oxidized lead in a solution of sulfuric acid and water settles on the positive plate during battery discharge, while sulfur dioxide is reduced on the negative side. Charging a battery is the reverse process.
On a note! In the process of replenishment of nutrition in the electrolyte, the content of sulfuric acid decreases, and the volume of water increases.
The device has a body, +/- electrode and output, a separator, an external current collector for a block of plates of the same name (butt), support prisms, a cover, a threaded plug, and a connecting bridge.
Details description: frame - fire-resistant material, plates - metal gratings.Different-pole elements (grid filling): 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 electrodes of different poles in order to avoid a short circuit (comes from vibrations of the engine or the entire vehicle).
For electric transport, there are several types of batteries: 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 off, and its replenishment is while driving.
In traction units, the opposite is true, they are designed for long-term and stable energy supply (work everywhere).
Buffer batteries are effective at small discharges. They are 20% smaller than traction ones, respectively, and cheaper, but their service life is practically 2 times less. Basically, their scope is test equipment and medical control systems.
On a note! AGM lead-acid batteries work great in buffer mode (about 12 years) and slightly less when used in deep charge / discharge mode.
Before you understand which battery is better to buy 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 no 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 wording has stuck.
In an alkaline accumulator, caustic sodium or potassium plays the role of electrolyte. In addition, graphite is present in the composition, which has a beneficial effect on conductivity, and various impurities normalize the working capacity and stability of the apparatus.
Note! An element with a “-” sign includes a metal alloy of cadmium, nickel and a certain powder. In each case, the ratio of the components is unique. And for the durability of the unit, lithium monohydrate, which is part of the electrolyte, is responsible.
The hybrid device is designed for the car. Composed of: 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 the codes. This is usually where experts help. The buyer will only need to decide which company is better to purchase the goods.
Each buyer sets himself the task of how to choose a battery so that it lasts 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 this is almost always the case, as many buyers claim. If we consider batteries for passenger cars (electric), then their average 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 vehicles is just beginning to “grow its career” . Most manufacturers set the service life to 5-8 years, in advance of failure, so that the owner can replace the battery in time.
In many batteries, the capacity is gradually reduced, so after several years of operation, a decrease in the electric vehicle's range from the initial value to 70-80% is noted.
On a note! A lithium-ion battery degrades its performance regardless of charge / discharge cycles, while most other devices reduce their life 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 topping up water (the last character in the marking): normal (N), small (L), very small (VL), with a control valve (VRLA). This indicator indicates the type of service, indicates whether the water level should be monitored, indicates the current parameter setting that is used during recharging.
As for power, calcium and hybrid plants are considered the most progressive. They are in great demand among modern motorists.
On a note! Calcium devices are installed only in cars, if they are mounted in a boat or a boat, they can be subjected to a deep discharge, which is best avoided.
As noted earlier, the 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, a variety of 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 turning over due to the jelly-like mass.
An important indicator is the cold scroll 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 intensity, while without changing the dimensions and weight of the product.
The main representatives of this segment are goods from foreign manufacturers, batteries are very popular among buyers. Feature of the presented goods - wide application. The cost of the battery depends on the technical base. Top firms:
Note! All models presented in the list of leaders at a price do not exceed the threshold of 6 thousand rubles.
The device with a charge indicator is used for powerful UPS, portable units, suitable for electric bicycles and scooters.
The body is made of ABC plastic, completely sealed, can be mounted in any position, subject to the type of lead-acid devices made according to the AGM method (no liquid electrolyte). Handles medium to high levels.
