Generally, lithium batteries for electric vehicles cannot be fast-charged at roadside stations. If the roadside fast charger is pulse-type, it may damage the lithium battery's protection board and easily cause false triggering. A malfunctioning protection board can lead to significant issues. The chemical composition of lithium batteries differs from lead-acid batteries, requiring constant voltage and current two-stage charging. Most roadside fast-charging stations are designed for lead-acid batteries, which can adversely affect lithium batteries. Even if there's no issue the first time, problems may arise subsequently. Using roadside fast-charging stations inherently comes at the cost of reduced battery lifespan. Even for lead-acid batteries, frequent use of fast charging is not recommended.

How many liters of engine oil should be added to a BMW 320?

The recommended engine oil refill amount for a BMW 320 during an oil change is approximately 6.5 liters. You can verify the exact oil level after completing the refill. BMW 320 Engine Oil Specifications: The BMW 320 requires 5W30 grade engine oil, preferably fully synthetic. Since the BMW 320 engine is turbocharged (as opposed to naturally aspirated), its engine structure is more compact with more complex operating conditions, demanding higher performance from the oil. It requires oil with good fluidity, ideally fully synthetic. BMW 320 Oil Level Guidelines: The oil level should be maintained within the proper range. Both excessive and insufficient oil quantities can cause damage to the engine. Too much oil may increase engine load, impairing performance; prolonged overfilling can damage the exhaust ventilation system, increase carbon deposits, and create a false impression of oil burning. Insufficient oil levels generally compromise the engine's overall lubrication effectiveness, particularly for components relying on crankshaft splash lubrication, potentially leading to accelerated wear or even failure.

What Does Dual Drive in Cars Mean?

Dual drive in cars refers to either the front two wheels or the rear two wheels being driven, while the remaining two wheels follow the main driven wheels on the road, which is relatively more fuel-efficient. The characteristics of dual-drive vehicles and other drive types are as follows: Characteristics of Dual-Drive Vehicles: Front-wheel-drive vehicles do not require a driveshaft for the rear wheels, so there is no central hump, resulting in lower handling limits but good stability. Rear-wheel-drive vehicles have a central hump and are more prone to losing control in rain or snow, but they offer higher handling limits. Dual-drive vehicles are more suitable for urban driving and may struggle in off-road conditions. Four-Wheel Drive (4WD) Systems: Four-wheel drive means each tire has power, but it can be categorized into full-time 4WD, part-time 4WD, and on-demand 4WD. Overall, 4WD improves vehicle stability on slippery surfaces. If equipped with locking mechanisms (such as differential locks, limited-slip differentials, or electronic traction control systems), it can significantly enhance off-road performance.
