Tesla utilizes 18650 batteries produced by Panasonic. After the official production of the Model 3, the new 21700 battery will replace the 18650, becoming the new cell. More details about Tesla's batteries are as follows: 1. Tesla's earliest Roadster used Panasonic's NCR18650A battery, with a rated voltage of 3.6V and a capacity of 3.1Ah. The previous 85kWh battery pack used the NCR18650B battery, with a rated voltage of 3.6V and a capacity of 3.1Ah. 2. The 21700 battery is a ternary lithium battery, with the cathode material being lithium nickel cobalt aluminum oxide (NCA). This cylindrical ternary battery currently offers the highest energy density among power battery solutions. Compared to prismatic batteries, although this type of battery has higher energy density, its stability is poorer, requiring excellent BMS (Battery Management System) support. 3. Under current conditions, the energy density of the 21700 battery system is around 300Wh/kg, approximately 20% higher than the original 18650 battery system's 250Wh/kg. Additionally, according to Panasonic's test data on power lithium battery cells, the volumetric energy density of its 21700 battery is significantly higher than that of the 18650 battery cell. The improvement in single-cell energy density far exceeds the 20% increase observed after grouping.

What are the reasons for the high fuel consumption of the Haima M5?

The reasons for high fuel consumption include: 1. Dirty engine oil and air filter: If the vehicle has not been maintained for a long time, dirty engine oil and air filter can also lead to increased fuel consumption. Dirty engine oil causes poor lubrication, increasing resistance in various moving parts of the engine, which requires more energy to overcome, resulting in higher fuel consumption. A dirty air filter restricts airflow, requiring more energy for intake and leading to incomplete combustion, where some gasoline is not fully burned and is expelled, thus requiring more gasoline to cover the same distance. 2. Spark plugs need replacement: Spark plugs are often overlooked, with some people not replacing them even after 100,000 kilometers. Although spark plugs can still function beyond their lifespan, insufficient ignition energy can cause delayed ignition, missing the optimal timing. For example, gasoline should ideally ignite when the piston is near top dead center, but insufficient ignition energy may delay ignition until the piston starts moving downward, leading to power loss and wasted energy. This also results in incomplete combustion, further increasing fuel consumption. 3. Low tire pressure: Insufficient tire pressure increases the contact area between the tires and the road, raising friction and rolling resistance, which increases fuel consumption. Low tire pressure also shortens tire lifespan and increases the risk of blowouts on highways. Therefore, tire pressure should be checked regularly, at least every two months. If the vehicle has a tire pressure monitoring system, it can be checked directly; otherwise, a tire pressure gauge should be used to measure each tire manually. 4. Incorrect sensor data: For example, coolant temperature sensors and oxygen sensors. If these sensors are not completely faulty but provide inaccurate data, they may not trigger a warning light, making it difficult to detect without checking the data stream with a diagnostic tool. For instance, a coolant temperature sensor showing a lower temperature or an oxygen sensor indicating excessive oxygen content can cause the engine control unit to inject more fuel, leading to incomplete combustion and higher fuel consumption. 5. Excessive carbon buildup: Carbon deposits can accumulate in the throttle body, fuel injectors, intake manifold, and piston tops. Excessive carbon deposits in any of these areas can cause incomplete combustion, leading to increased fuel consumption.

What should I do if the Nissan Teana engine is too noisy?

Reasons for excessive engine noise in Nissan Teana: 1. Excessive carbon buildup in the engine. 2. Improper use of engine oil or dirty engine oil. 3. Loose screws on the engine underguard. Tighten or adjust the screws on the engine underguard. 4. Aging engine mount pads. The mount pads support the engine and can only be replaced when aged. 5. Loose plastic parts in the engine compartment, such as the engine cover or intake pipe, which can be tightened. 6. Abnormal noise from the engine belt, including the power steering belt and alternator belt. Aging, overly loose, or overly tight belts can cause noise and should be replaced or adjusted. 7. Engine knocking. This can be caused by excessive carbon buildup inside the engine or the use of substandard fuel, requiring carbon cleaning and fuel replacement.

How far must the front of the car exceed the crosswalk before turning?

You can only turn after the front of the car has completely passed all crosswalk lines. Tips for turning while driving: New drivers must drive slowly, especially when turning. It's essential to decelerate in advance—only by slowing down can you pass safely or correct mistakes in time. When turning, always check the rearview mirror to ensure there are no vehicles or pedestrians behind or to the side before proceeding. Steering wheel control is crucial. For a sharp turn, turn the steering wheel as much as possible, then gradually straighten it after completing the turn. For a wide turn, turn the wheel slowly. Be mindful of blind spots when turning. Beginners often focus only on what's ahead or to one side, neglecting blind spots, which can lead to hitting the curb or causing a scrape. Always check for obstacles below the rearview mirror, and if necessary, open the door to look before turning. Precautions for turning: When turning, adjust the steering wheel according to the road's curvature and coordinate with the driving speed to ensure appropriate turning angle, timing, and timely correction of direction. Never take both hands off the steering wheel to avoid losing control and causing danger.

What does the 'batt' display on Honda dashboard indicate?

When the Honda dashboard displays 'batt', it means the battery in the vehicle's smart key is running low and needs to be replaced as soon as possible. Here are some additional explanations: 1. The flashing 'batt' icon will disappear once the battery in the smart key is replaced. 2. If it doesn't disappear, you can turn off the ignition switch and restart the vehicle, and the indicator light should stop flashing. 3. If the light remains on, it's necessary to have the key checked at a repair facility to see if there's an issue with the key itself. 4. The battery in a car key typically lasts about two years. When the battery is low, it can affect daily locking/unlocking and the normal starting of the vehicle. 5. Therefore, when the vehicle indicates low key battery, or when the remote control distance becomes shorter or less responsive, it may be due to low battery power. In severe cases, the 'batt' prompt on the dashboard will light up, indicating that the key battery needs to be replaced.
