Why are lithium batteries better than lead-acid batteries?

We should compare everything we buy and have a comprehensive understanding of all aspects. The same is true for buying electric cars. For example: maintenance, charge and discharge loss, change in the future, the battery and so on, will spend a lot of money in the future!

As we have learned: the electric vehicle replacement cycle of average consumer is around 4-5 years. Lead-acid batteries although cheap, are costly to replace every year. Generally speaking, the price of a better lead-acid battery is about 600 Yuan, so in the same electric car, only replace the battery will spend about 2,400 Yuan.

Consider electric cars with lithium-ion batteries. Buy a lithium battery electric car is about 3500 Yuan. The lithium battery is guaranteed for about three years, which means we don't have to pay extra money to replace the battery in these three years. And lithium battery life is very long, basically in about 5 years. In other words, as long as we take good care of ourselves, we won't have any other expenses on electric cars for 5 years.

So, such a comparison, on the surface, the original buy lead-acid battery electric cars cheaper, in fact, this is false benefits!

Lithium battery with no memory, do not pay attention to charging!

In ordinary lead-acid battery electric vehicle charging, always worry about battery memory effect occurs. Once using the lithium battery you can relax. Because lithium battery with no memory effect in the process of daily charge you don't need too cautious!

Lithium batteries are less polluting than lead-acid batteries!

Lithium battery compared with ordinary batteries more green, little pollution to the environment, long service life can avoid common battery replacement brings pollution to the environment.

Compared with bulky lead-acid batteries, lithium battery light!

Compared to lithium batteries in the lead-acid battery and the quality will be much smaller size, usually, lead-acid battery in 16-30 kg weight, volume is larger; And lithium battery weight is in commonly 2.5 3.0 kg, volume is relatively small, light and handling convenient too. General lithium battery electric vehicle light and beautiful, convenient to move, a lot of lithium battery electric vehicles can be folded.

Lead-acid batteries explode? Lithium batteries are safer to use

Electric car spontaneous combustion explosion happens quite often, most are the result of the battery charge and discharge, experts explain, lead-acid battery charging time is too long, charging to the end of the poles into effective substances, if I continue to charge again, can produce large amounts of hydrogen, oxygen gas.4% when the concentration of the mixed gas in the air, and had no time to escape, too much, if the vent plug or gas flame will be an explosion, light damage to the battery, or hurt, the loss. That is, once the lead-acid battery overcharge, will increase the risk of explosion. Currently on the market of lead-acid battery didn't do any "overcharge protection", which makes charging especially in charge at the end of a high risk of lead-acid batteries.

Now lithium-ion batteries can very well to avoid this problem, like wisdom lithium dog BMS battery management system can provides the full protection to battery, features include: charge/discharge in high and low temperature protection; Single section charge/discharge voltage protection; Charge/discharge over-current protection; Batteries equilibrium; Short circuit protection; Charging remind and so on. It can not only extend the service life of the battery, but also ensure the safety.

Lithium batteries are better. Lithium batteries are more than 3 times higher than lead-acid batteries in terms of volume to energy and weight to energy. Lithium batteries are smaller, lighter and have a longer cycle life.

How far it goes depends on the battery capacity. It doesn't make sense to say which is farther alone.

Both are 48 v20ah, for example, lithium and lead acid are basically the same, because they have the same capacity, but lithium is lighter, so it's a little bit further away than lead acid.

But if the lithium electricity is 48 v10ah, lead-acid is 48v 20ah, it must lead acid, needless to say. Who said simple point is that large capacity which runs far, lithium electricity advantage is lighter than the lead-acid, large current discharge, other are all the same.

Actually lithium-ion mainly relies on lithium ions move between the positive and negative to work. In the process of charging and discharging, li + embedded back and forth between the two electrodes and embedded off: when the rechargeable battery, li + embedded from the anode, after anode, electrolyte embedded in the cathode in the rich lithium state; Discharge is the opposite. Commonly used as electrode materials containing lithium batteries, one of the most negative are adopted graphite. Compared with lead-acid batteries, lithium-ion batteries, lithium batteries has light weight, large specific capacity, cycle long life and other advantages, as the old man electric off-road vehicle power supply, not only convenient lightweight portable charging, but also help the whole car lightweight and simplification of product design.

Lead-acid battery electrodes are mainly composed of lead and its oxide, the electrolyte is sulfuric acid solution. Lead-acid battery charged state, the positive main ingredients for lead dioxide, negative main ingredients to lead; Discharge state, the main components are all lead sulfate is negative.

Both batteries in addition to belong to the energy storage device, the other are not the same. Lead-acid batteries are safer and cheaper, but low energy density than lithium electricity, so the volume of lead-acid battery becomes larger.

At this stage, the battery (storage) technology research has not been able to obtain a breakthrough, "low cost, high performance" that the battery has not yet been put into commercial application before we can be of existing lead-acid battery and lithium battery together the excellent characteristic of transformation and upgrading, as at present and the future for a period of major research topic. Believe that the old man in the future electric car instead of walking, and even the development of the industry as a whole electric car instead of walking with a more clear direction.

For now the penetration of "lithium trams" is far lower than using "model of lead-acid battery" products, its reason or is that the current lithium battery cost is still relatively high. Therefore, in the design of "lithium trams" existing product, use to reduce the capacity of lithium-ion batteries more configuration, to reduce the vehicle implementation cost accordingly, which makes the existing models too simplification of "lithium trams" products. At present, a lot of li-ion battery products on the market, for example, "electric bicycle" is not very far away and continuing models, but like four-wheel electric cars, electric car instead of walking round old man these are far onward the current situation was more suitable for lead-acid batteries, that study the related problems of AoXiang electric hope to let more consumer to recognize "lead acid lithium batteries and electric" analysis of the two, that whether you have realized that you choose and it should be how to choose the battery electric car instead of walking.

Old car battery electric instead of walking parsing of damage

There are many old friends at the time of using old electric car instead of walking, this or that kind of potential problems may be battery problems, lead to electric car instead of walking you old man not to walk, or walk not far away, today AoXiang electric together help you parse the stand or fall of the battery.

Battery as a "convenient power supply" has been widely used by people, especially in the use of new energy electric car instead of walking, with the popularity of electric scooter has been improving, more and more close to people's lives, but people have little knowledge of the battery.

Like the old electric car instead of walking the user mostly elderly, they knew little more on this aspect of knowledge, every problem is hand does not, in this recommendation these users both in the elderly and young people should study well battery operation and maintenance knowledge, in order to better safeguard their own electric car instead of walking, sometimes users may put forward how to bad loss too fast, your battery capacity can reduce battery repair, and how to maintain the battery and so on question, in this the cause of the battery damaged, battery repair and maintenance to make the following analysis.

1, "Overcharge" causes damage to the battery

"Too" is an excessive amount of electric car instead of walking to the old battery charge resulting from the chemical and physical properties of battery have the phenomenon of damage.

Electric car instead of walking the charger is in charge at the same time to the series of battery charging, the battery of high voltage will be full of electricity, low voltage of battery full even after the meeting has been in charge, because the charger is general voltage or stop charging set, therefore, to fully charged battery is a state of "imitation"."Pressure difference" hour has little impact on the battery, "pressure difference" is big. Always "overcharged" battery pool will produce electrolyte thermal reaction intensified, until this section of the storage battery charge bad.

2, "Power loss" causes the battery to break down

The old man said electric car instead of walking "power loss" is the battery when the battery is low, low voltage to excessive discharge of a destruction of battery plate coating phenomenon. Want to know, any vehicle the working voltage of electric equipment has a standard range, more than this range of electrical short circuit or even burned easily, less than the range of appliances cannot start or work, even affect the service life, automotive electronics and battery.

3, overload of large current discharge the battery badly damaged

Electric car instead of walking in the start, acceleration instantaneous current is large, typically up to 20 a - 50 a, according to the size of the electric motor power, general control within 10 a normal discharge current as well. Due to the instantaneous electric current too big, overload is load overweight in electric vehicles, such as too much cargo, manned, overload can make the battery discharge load increasing, large current discharge for a long period of time, will directly affect the plate coating, speed up the process of plate to soften. There is bad roads also can make electric cars frequent braking and start. Such as potholes, meet a red light, barriers and so on. These are the factors causing large current discharge. This is because the motor power, the greater the greater the discharge current, the greater the damage of the battery.

4, Plate vulcanization causes battery damage

What is the battery sulfide? On plate to generate white hard lead sulfate crystallization, charging and very difficult to translate into active material of lead sulfate, which is the sulfuric acid salinization, hereinafter referred to as "curing".

The cause of the lead sulfate

This kind of lead sulfate has poor electrical conductivity, high resistance, low solubility and dissolution speed, and it is difficult to recover from charging. Thus become the capacity to reduce and shorten the life of reason. Sulfide is the main sticking point, reduce the battery capacity but high current damage to the battery plate is the crux of the electric vehicle battery capacity to reduce more.

In addition to the above main reasons for battery damage, poor battery quality, plate fall off, electrolyte leakage, water loss, shell damage, battery terminal broken wiring is also the cause of battery damage, there are some potential factors that we have not even found. If you love your elderly electric scooter, then you should take care of every part of it, especially the battery, which directly affects the life of your electric scooter.
