As the core component for starting and powering the vehicle, the performance of the car battery is directly related to the reliability and service life of the vehicle.
BMW Car Battery Maintenance Tips
When a BMW vehicle fails to start, it is advisable to pause for 5 seconds before attempting to restart. Too many successive start attempts can lead to excessive battery discharge and damage. In cold temperatures, where the starting current demand is higher, it is crucial to exercise greater caution.
Using car accessories like the audio system and air conditioning for extended periods while the engine is off can heavily burden the battery. Therefore, it is recommended to minimize the use of these electrical appliances once the engine is turned off, thereby preventing the battery from undergoing excessive discharge.
Long-term parking will deplete the battery. To maintain a fully charged battery, recommend starting the vehicle and letting it run for half an hour or driving it for 30 kilometers every 10 days.
Most BMW batteries are maintenance-free, but it is still necessary to regularly check the battery connection, voltage, and appearance. If any abnormality is found, go to the 4S store for inspection or replacement in time.
Tesla car battery maintenance tips
Tesla advises periodic partial charging and discharging of battery packs, maintaining a 50%-80% charge level every few weeks. Avoiding prolonged full or complete discharge helps preserve battery health and prolongs its lifespan.
When using fast charging in winter, preheating the battery in advance can effectively extend the battery life. Tesla’s car system can automatically preheat the battery. The owner only needs to plan the charging route and the system will automatically complete the preheating.
Choose the right charging pile. Tesla can use official or third-party charging piles, and there is little difference in performance between the two. Car owners who pursue cost-effectiveness can choose third-party charging piles with national standards.
Set the charging limit according to the battery type. For example, lithium iron phosphate batteries are resistant to high temperatures but not low temperatures, and can be charged to 100%. However, ternary lithium batteries are resistant to low temperatures and cannot be over-discharged. Charge them to 80%-90% daily, and fully charge them occasionally to prepare for long-distance driving.
Avoid waking up the vehicle frequently. Tesla will enter a sleep state when parked. Opening the app wakes up the vehicle each time, leading to quicker power consumption.
Maintain a suitable temperature and avoid the impact of extreme temperatures on the battery. When parking, choose a place with moderate temperature and avoid extreme cold or hot environments.
Update vehicle software in a timely manner. Some updates involve battery management improvements, which help improve battery efficiency.
Although Tesla battery packs are highly integrated, it is still necessary to regularly check the battery health to understand whether the capacity and charging speed are normal.
