Electric vehicles can wade through water no deeper than 40CM. Here are specific details about electric vehicle waterproofing: 1. Waterproof performance: Key components of new energy electric vehicles such as the motor, controller, and battery are all waterproofed and well-protected, safely enclosed in sealed devices. Therefore, they are generally unaffected by rain. 2. Precautions: Do not leave new energy electric vehicles in open-air environments during rainy days. If the vehicle gets slightly wet, simply ventilate and dry it. However, do not charge the vehicle immediately after it gets wet from rain. Always place the vehicle in a ventilated area to dry before charging to avoid short circuits that could lead to spontaneous combustion.

I recently researched the issue of electric vehicles driving through water and found that it mainly depends on the battery pack's sealing level. Most mainstream EVs have batteries that meet the IP67 standard, meaning they can be submerged in 1 meter of water for 30 minutes without leakage. However, don't take risks when actually driving - be cautious if water exceeds half the wheel height. When I drove my Tesla through deep water, maintaining a steady speed was crucial, keeping it below 10 km/h. If you notice anything abnormal after water exposure, like warning lights on the dashboard, immediately power off and call a tow truck. Remember that underbody impacts are most dangerous - rocks could damage the battery's sealing layer, so it's best to avoid water of unknown depth.

As a long-term electric vehicle owner, the safest approach is to refer to the vehicle manual. My BYD Han clearly states a maximum wading depth of 30 cm, approximately one-third of the wheel height. When encountering waterlogged roads, I always step out to measure the water depth with a branch while observing how preceding vehicles pass through. The advantage of EVs in water lies in the absence of an intake pipe, but the battery pack is usually positioned at the lowest point of the chassis. Last week during rain, I suddenly encountered a deep water zone and immediately activated crawl mode to pass through at a steady speed. Afterwards, I specifically checked the charging port for any water accumulation. I recommend keeping an emergency hammer in the car – if the vehicle fails during water crossing, it can be used to break the window for escape.

The water-wading capability of new energy vehicles is actually much stronger than that of traditional fuel-powered cars. Nowadays, high-end electric vehicle battery packs are sealed to IP68 standards, meaning they can theoretically operate normally even when submerged in water. However, in practical use, it's best not to exceed knee-deep water, especially when encountering flowing water, extra caution is needed. When driving my XPENG, I activate the wading mode in deep water areas, which automatically adjusts the battery cooling system. Remember to turn off the auto start-stop function when wading through water, and never attempt to restart the engine if it stalls. Once, I encountered a heavy rainstorm while driving in the suburbs, so I simply took a detour—after all, the repair costs for electric vehicles are prohibitively expensive.

Can You Still Drive If the Car Battery Is Smoking?

You cannot continue driving if the car battery is smoking. Continuing to drive may cause the wiring to burn out, and the battery fluid may evaporate, leading to the battery becoming unusable. Possible reasons for the battery smoking include: 1. Damaged separator plate. 2. Aging circuits or the battery reaching the end of its lifespan. 3. A faulty charger causing excessively high charging current and voltage. 4. Poor-quality or damaged separator plates, allowing active material from the electrodes to pass through. If the separator plate is of poor quality, impurities may form when ions cross it, causing a short circuit between the plates. 5. A large short-circuit current can scorch the separator plate, worsening the short circuit between the plates and further increasing the short-circuit current, creating a vicious cycle. Eventually, smoke may be emitted from the battery's vent.

What to Do When There Is Water Under the Driver's Side Floor Mat?

How to handle water under the driver's side floor mat in a car: 1. The water under the driver's side floor mat is most likely condensation from the air conditioning. 2. When the car's air conditioning is in cooling mode, it generates a significant amount of water, which is typically drained outside the vehicle through a drainage hose connected near the condenser. If this hose was not properly connected to the undercarriage during manufacturing, the water may accumulate inside the car. 3. If the issue is minor, you can locate and reconnect the hose yourself. However, if water has entered the exhaust pipe, do not start the engine. Instead, arrange for a tow truck to take the vehicle to a 4S service center for professional repair. 4. If the water accumulation is due to clogged drainage holes or channels, preventing rainwater from draining properly, promptly clean the drainage outlets, remove the water under the floor mat, dry the carpet surface, and replace the mats with waterproof full-coverage floor mats.

What Causes the ABS Light to Illuminate After a Vehicle Inspection?

There are various states of the ABS light being on, with different causes and solutions for each state. The details are as follows: State 1: ABS warning light stays on (most common). Cause 1: The ABS speed sensor's sensing part is covered by dirt, mud, or other contaminants, affecting its ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle speed and the wheel slip rate, thus failing to issue appropriate commands to adjust braking. Solution: Clean the dirt off the speed sensor and adjust the gap between the speed sensor and the signal ring to restore normal function. Cause 2: Loose connections between system lines or poor contact of the ABS relay lead to signal issues, causing system failure. Solution: Check the line connections and reconnect any loose parts. State 2: ABS warning light intermittently illuminates but turns off when accelerating. Cause: When multiple vehicle electrical devices are in use, the battery voltage drops below 10.5V. As the engine speed increases and voltage rises, the ABS light turns off. The ABS system's power supply voltage is too low, possibly due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light stays on after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact of the ABS hydraulic valve body; poor contact in the ABS hydraulic valve body's wiring connector; ABS computer malfunction. Solution: Loosen the grounding screw of the hydraulic valve body, then retighten it, cleaning the contact surface if necessary; check if the connector gap has widened; replace the ABS or ABS/ASR computer. State 4: ABS warning light illuminates during high-speed driving. Cause: During high-speed driving, the ABS computer detects a significant discrepancy between the rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: With the engine running, press the brake pedal, push the brake switch linkage down fully with a finger, then release the brake pedal to complete the self-setting position; replace the brake light switch. If the ABS warning light is on, it is advised not to continue driving. An illuminated ABS light indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, making it difficult for the driver to slow down or adjust the vehicle's path, posing significant safety risks.

What is Brake Pedal Free Travel?

Pedal from the stop position to the step to the end of the distance. The following is part of the introduction about the brake pedal free travel: Function: The pedal free travel is a function set to ensure that there is no brake drag and the brake is completely released. Measurement: When measuring, place a straightedge between the brake pedal and the cab floor, press the brake pedal down by hand until there is resistance, and record the straightedge reading. Then release the pedal and look at the straightedge reading again. The difference between the two readings is the pedal free travel. The free travel of the hydraulic brake pedal is generally 15-20mm, and it should be adjusted according to the value specified by the vehicle model.

What to Do When There's Abnormal Noise During Low-Speed Braking?

Reasons for abnormal noise during low-speed braking include excessive wear of brake pads, improper contact surface, water exposure, and wear. Specific explanations are as follows: Excessive wear of brake pads: Leads to the exposure of friction material fixing points, causing friction with the brake disc or brake drum and resulting in abnormal noise. Solution: Replace the brake pads. Improper contact surface: After replacing the brake pads, if the contact surface with the brake disc or drum does not fit properly, it can form point or line contact, leading to abnormal noise. Solution: Perform a break-in for the vehicle. Water exposure: Brakes may produce abnormal noise after the car has been exposed to water. Solution: Handle according to the water drainage situation, remove accumulated water, and replace the corresponding parts. Wear: Excessive wear of the brake disc or brake drum. Solution: Replace the brake disc or brake drum.
