What battery does BYD Qin use?

BYD Qin battery type is BYD lithium iron phosphate battery. The total voltage is 500V, the energy is 13 degrees, and the cell voltage of the lithium iron phosphate battery is 3.2V. The following are the characteristics of lithium iron phosphate batteries: 1. High energy density. In 2019, some excellent battery manufacturers can reach the level of 175-180Wh\u002Fkg. Some powerful manufacturers use stratification technology to increase capacity, or can reach 185Wh\u002Fkg. 2. Good safety performance. The electrochemical performance of the cathode material of the lithium iron phosphate battery is relatively stable and has a stable charging and discharging platform. Therefore, the structure of the battery will not change during the charging and discharging process, and will not burn or explode, and even. in case of short circuit, overload or extrusion, acupunctureand other special conditions, it is still very safe. 3. Long service life. The lifespan of lithium iron phosphate batteries generally reaches 2,000 times, or even more than 3,500 times. The energy storage market requires more than 4,000-5,000 times, ensuring a service life of 8-10 years, which is longer than the life of batteries. ternary batteries more than 1,000 times.

The advantages and disadvantages of ternary lithium iron battery and lithium iron phosphate battery

Lithium iron phosphate batteryThe lifespan can reach 2000 times above, but we always calculate the lifespan at 80%, which is 1600 times, which will probably decrease to around 5%.

Lithium iron phosphate battery is a type of lithium-ion battery. It refers to a lithium-ion battery that uses lithium iron phosphate as the cathode material. , temperature resistancees and good cycle performance.

Like ternary lithium batteries, the theoretical life of lithium iron phosphate batteries also exceeds 2,000 charge and discharge cycles. Even if charged once a day, they can last more than five years, generally speaking. domestic use is once every three days. It can be used for about eight years if recharged. However, due to the poor low temperature performance of lithium iron phosphate batteries, the life of lithium iron phosphate batteries will be relatively longer in the south.

The charge and discharge cycle life of lithium iron phosphate batteries can generally reach more than 2,000 times. Even for a car with a range of only 70 kilometers, 2,000 cycles can support 140,000 kilometers of pure electric driving. The only drawback is that the energy densitytick is weak and the attenuation at low temperature is obvious. Capacity will be reduced by approximately 10% at 0°C and capacity will be reduced by approximately 30% at -20°C.

Advantages of lithium iron phosphate batteries

There is no ternary lithium iron battery, it is a ternary lithium battery.

Advantages:

Ternary lithium battery: high energy ratio, high voltage, good power characteristics, but poor safety. Good temperature range;

Lithium iron phosphate battery: relatively low electrical energy, medium voltage, stable performance and good safety. The temperature range is better. The lifespan of lithium iron phosphate batteries is generally more than 1,000 cycles and can reach 2,000 cycles. Electric buses use lithium iron phosphate batteries.

Disadvantages:

Ternary lithium battery: high capacity, good consistency, short lifespan,relatively large size and poor low temperature performance.

Lithium iron phosphate battery: small in size, can be installed with larger capacity, performance does not decline much in winter, initial capacity is large, has obvious mileage advantage per compared to lithium iron, but will decrease considerably later. in life.

Detailed information:

< p>On the left side of the lithium iron phosphate battery is the positive electrode made of LiFePO4 material with olivine structure, which is connected to the positive electrode of the battery by aluminum foil. On the right is the negative electrode of the battery made of carbon (graphite), which is connected to the negative electrode of the battery by a copper foil. In the middle is a polymer separator that separates the positive electrode from the negative electrode.ve. Lithium ions can pass through the separator but electrons cannot pass through the separator. The battery is filled with electrolyte and the battery is sealed by a metal case. ?

1. Increased safety

The power of iron phosphate completely solves the cobalt problem. The potential safety risks of lithium oxide and lithium manganate are manifested in the fact that the bond strength of the Phosphate chemical bond is stronger than that of the traditional transition metal oxide structure, so the structure is more stable and less likely to break free. oxygen.

2. Long lifespan

The lifespan of lead-acid batteries is about 300 times, with a maximum of about 500 times, while the lifespan of lithium iron phosphate batteries reaches more than 2,000 times with one charge usee standard (0.2 C, 5 hours), up to 2,000 times.

Lead-acid batteries of the same quality last “six months for new ones, six months for old ones and six months for repairs”, or 1 to 1.5 years at most. When lithium iron phosphate batteries are used under the same conditions, the theoretical service life will reach 7-8 years.

In overall consideration, the performance-price ratio is theoretically more than 4 times higher than that of lead-acid batteries. High current discharge can quickly charge and discharge at a high current of 2C. Under a special charger, the battery can be fully charged in 40 minutes at 1.5C, and the starting current can reach 2C. performance.

3. Support for fast charging

In terms of charging speed, lithium iron phosphate also has greater advantages. The fast charging support feature allows it to support fast charging speede of 2C (C). Charging parameters, for example, for a battery cell with a capacity of 1000 mAh, the 2C current is 1000 mAh*2 = 2000 mAh). This can significantly reduce charging time. Currently, most power supplies on the market use a standard charging voltage of 5V, and the charging current is generally 0.2C.
