Hello, regarding the question of whether to buy lithium batteries or hydrochloric acid batteries when buying an electric car?
Electric vehicles are a very commonly used means of transport for us. Among the different performances of electric vehicles, cruising range is particularly important. The main factor that determines the cruising range of an electric vehicle is the battery. , including battery type and model. Capacity, etc. Currently, electric vehicle batteries mainly include lead-acid batteries and lithium batteries. When choosing a battery, is it better to choose lead acid batteries or lithium batteries? Which is the most practical? Which is more profitable?
Today I will explain it clearly to everyone.
The battery is the reserve source of vehicle energyare electric. Although there are many types of batteries in the electric vehicle battery market, including graphene batteries, black gold batteries, lithium iron phosphate batteries, etc., the main ones are as follows. are lead acid batteries and lithium batteries, two main categories, today we analyze their real value through the different advantages and disadvantages of the two batteries.
Analysis of 3 categories of lead-acid batteries
Lead-acid batteries are particularly used batteries in the market, accounting for approximately 75% of the current market, because they are economical. , easy to replace, and because of its high safety features, it is deeply loved by the majority of electric vehicle users.
Lead-acid batteries are divided into three subcategories: ordinary lead-acid batteries, black gold batteries and g-acid batteries.raphene. They have different cruising ranges and different prices under the same model. Generally speaking, the price of graphene batteries is higher and that of ordinary lead-acid batteries is lower. But the actual usage share is the opposite.
For example, although graphene batteries have a longer battery life than ordinary lead-acid batteries of the same model, their price is also much higher, so most users prefer graphene batteries. ordinary lead.
Analysis of three categories of lithium batteries
In recent years, the growth share of lithium batteries has been relatively large. In the early years, the market share of lithium batteries was less than . 10%. Today it reaches around 25% in some places. Lithium batteries mainly include three types: ternary lithium batteries, lithium batteriesDiscrete lithium iron and lithium iron phosphate batteries. lead acid batteries above. The more commonly used ternary lithium battery accounts for a larger market share and is relatively affordable in price.
Lead-acid batteries are more convenient and cost-effective
Why am I speaking so directly about the benefits of lead-acid batteries? After all, lead-acid batteries are more convenient than ordinary car users, which is reflected in two aspects:
1. Lead-acid batteries are more affordable, usually only a third of the price of the same. type of lithium batteries.
For electric vehicles, they are mainly practical and easy to use. Ordinary people generally don't need particularly long battery life. Although lithium batteries have a long range and are relatively lightweight, most people currently drives luxury vehicles. Large or small charter vehicles are large enough to accommodate batteries, but the price is much lower, which is naturally what ordinary people prefer.
2. Lead-acid batteries are safer and rarely spontaneously combust.
The spontaneous combustion phenomenon caused by electric vehicle batteries in the past two years mainly affects electric vehicles equipped with lithium batteries, because lithium batteriesThe internal density is high and the thermal resistance is bad. If it is overheated, such as in summer or charged too long, and exceeds the charging temperature, it can cause spontaneous combustion. Especially low-grade lithium batteries need to be more careful in terms of safety. Lead-acid batteries have relatively high stability and generally rarely spontaneously ignite.
3. THELead-acid battery replacement is more convenient and more valuable.
Although the lifespan of lithium batteries is generally twice that of lead-acid batteries, lead-acid batteries are more convenient when replacing them. Generally, lead acid batteries can be recycled, i.e. used lead. -acid batteries can always be recycled for depreciation. But if the lithium battery is worn out, it has no recycling value.
Lithium batteries have longer life, longer battery life and lighter weight.
Whether it is better to use lithium batteries or lead acid batteries for electric vehicles
Electric vehicle batteries are generally lead-acid batteries and lithium batteries. To identify if it is a lithium battery:
1 Look at the volume. Generally, lithium batteries sont smaller than lead-acid batteries;
2. Weight, lithium batteries are smaller than lead acid batteries. Lead acid batteries are lightweight;
3. Open the case. Lead-acid batteries are generally made up of 4 or 6 small batteries, otherwise they are lithium batteries. .
Detailed information
Advantages of lithium batteries
1 . The energy is relatively high. The energy density is approximately 6-7 times that of lead-acid batteries.
2. long duration. The lifespan can reach more than 6 years. The lithium iron phosphate battery as the positive electrode is charged and discharged at 1C (100% DOD) and has a record of 10,000 times usage.
3. The rated voltage is high (the operating voltage of a single unit is 3.7V or 3.2V), which is approximately equal to the series voltage of three nickel-AC rechargeable batteriesdmium or nickel-metal hydride, which facilitates the formation of battery power. Lithium batteries can go through a new type of lithium battery voltage regulator technology to adjust the voltage to 3.0V to adapt to the use of small electrical appliances.
4. It has high power endurance, among which the lithium iron phosphate lithium ion battery used in electric vehicles can achieve a charge and discharge capacity of 15-30°C, which makes it easier to start and accelerate at high intensity.
Whether electric vehicles use lithium batteries or lead-acid batteries depends on many factors. From a performance perspective, lithium batteries have higher energy density and lighter weight. Lithium batteries are more expensive and require more complex charging equipment and higher charging voltages.s high, which increases the cost of use and difficulty of charging. Although lead-acid batteries have lower energy density and heavier weight, they are relatively inexpensive and the equipment and charging methods are relatively simple.
