Personally, I think BYD batteries are significantly better.
Batteries mainly concern lifespan, stability, temperature, charging speed and durability. They are also difficult to maintain when used in new energy vehicles.
The maintenance difficulty of BYD's blade battery is much better than that of CATL. The blade battery can only repair the broken part.
CATL batteries are only better than blade batteries in terms of charging speed, but we usually charge them at night and it doesn't take much longer.
The Ningde era uses batteries of ternary materials. The reason they are called ternary materials is because they use several rare elements, such as cobalt. The energy of ternary materials is denser, but. not very sure.
BYD uses batlithium iron phosphate materials, which have a lower energy density than ternary materials, but have a higher safety factor.
CATL's bet on ternary material battery technology is more of a product of the times, as new energy sources benefit from a large number of government subsidies, and the condition of subsidy is that the longer the battery life, the higher the subsidy.
All new energy vehicle manufacturers must use domestic battery technology if they want to receive subsidies.
Based on the points above, the CATL era is more of a product of the times and captured many things. BYD pays more attention to safety and does not deliberately pursue energy density.
Ordinary materials have higher energy density than lithium iron phosphate batteries, mays BYD's lithium iron phosphate batteries are safer and have a slightly shorter lifespan.
Personally, I prefer BYD's approach.
BYD's batteries are much better and safer
Of course, Ningde's batteries are much better, mainly Due to the manufacturing process, Ningde batteries have very good consistency. Simply put, all indicators on every factory battery are almost exactly the same! BYD can't do it
Half a catty is equivalent to eight taels.
BYD's lithium iron phosphate battery has a lifespan of 12 years or 160,000 kilometers, and the number of cycles can reach 3,000 to 4,500 times, granting more attention to standard driving habits and regular maintenance; of your car and batteries, it can be used for about 12 to 15 years.
Battery lifee ternary lithium is 4 to 6 years. The theoretical life of the ternary lithium battery is about 1500 times, and the actual life is about 1200 times. If the theoretical range of an electric vehicle can reach 200 km, the actual cruising range can reach 160 km, the maximum cruising range can reach 192,000 km, and the actual cruising range can reach 153,600 km.
According to the requirements of "National Standard GB/T31484-2015", the national standard for battery life of electric vehicles is: when the battery capacity drops to 80% of the initial capacity, the number of cycles is more than 1000 times; or the battery capacity decreases to 90% of the initial capacity, the number of cycles is more than 500 times.
Methods to extend battery life:
1. Pay attention to the temperature of the environment: do not use it in an enenvironment where the temperature exceeds 60 degrees Celsius. the temperature is below minus 5 degrees Celsius, stop charging the battery or vehicle.
2. Long-term storage requires safe power off: if not used for a long time, it is recommended to disconnect the maintenance switch of the power battery, so that the battery power supply is disconnected. internally, without causing power loss and ensuring battery durability.
3. Do not overcharge or discharge the battery: Charging daily can improve battery activity, but waiting until it is dead before charging will shorten its life.
