What is the service life of BYD Tang EV’s new energy vehicle power system?

The service life of BYD Tang EV’s new energy vehicle power system is affected by many factors, including battery technology, usage habits, external ambient temperature, and charging habits. The following is a detailed analysis of its service life:

1. Battery technology:

• BYD Tang EV uses lithium iron phosphate batteries. Compared with other types of batteries, such as ternary lithium batteries, lithium iron phosphate batteries have a longer cycle life, theoretically up to 2,000 times.
• The theoretical life of lithium iron phosphate batteries can reach 7 to 8 years, but the actual service life may vary depending on usage and conditions.

2. Usage habits:

• Reduce slamming on acceleration and avoid instantaneous high current discharge when driving, which will help extend the battery life.
• Regularly charging and discharging the vehicle fully, and keeping the SOC state of charge between 30% and 80% is beneficial to extending the battery life.
• If the vehicle is parked for a long time without use, it is recommended to keep the battery power between 40% and 60%.

3. External ambient temperature:

• Low temperature environment has an impact on the chemical properties inside the power battery, mainly the decrease in charging and discharging capacity. Therefore, the mileage tested in winter cannot represent the actual state of the battery.

3. Charging habits:

• Try to use AC slow charging to charge, which is conducive to the in-depth balance of the power battery and reduces damage to the battery.

3. Warranty period:

• The warranty period of the new energy battery pack provided by BYD is 8 years or 150,000 kilometers, which provides confidence guarantee for consumers.

In summary, the service life of the BYD Tang EV new energy vehicle power system is expected to reach 7~8 years or even longer under normal use and maintenance. However, the actual service life may vary due to individual differences, use environment and habits. Therefore, it is recommended that car owners use and maintain according to the requirements of the vehicle manual and maintenance manual to extend the service life of the power system.
