Why does the electric tricycle controller protection not work?

Electric tricycle controller protection not working reasons are introduced as follows: Introduction one: The protection device set by the controller generally has two types of devices. The most common one in daily use is overvoltage protection, which means when the external voltage of the controller exceeds the maximum voltage that the controller can normally work with, the protection circuit inside the controller is triggered, causing the controller to stop working. Introduction two: The other type utilizes a temperature-controlled switch to activate the protection circuit, meaning when the working temperature of the controller exceeds the temperature at which it can operate normally for a long time, the protection circuit is triggered to achieve the purpose of protecting the charger.

Can private cars enter the highway late at night?

Private cars are allowed to enter the highway late at night. Only passenger vehicles are prohibited from entering the highway between 2 AM and 5 AM, as the current highway restrictions apply only to large buses or sleeper vehicles. Unless there are special circumstances, such as heavy fog, heavy rain, icy roads, or major traffic accidents, the highway entrance will be closed. It is important to note that driving late at night should avoid fatigue driving, and due to poor visibility at night, extra caution is required. Precautions for driving on the highway at night: Before driving, check the vehicle's condition, including tire appearance and pressure, test the brakes, and always wear seat belts—both front and rear seats. Avoid placing unsecured items in the car. Novice drivers should avoid driving on the highway during snowy, foggy, rainy, or nighttime conditions. Before traveling, familiarize yourself with the entrance and exit points to avoid last-minute searches. When entering service areas or exiting the highway, it's best to glance at the speedometer, as prolonged highway driving can distort speed perception. Avoid letting large vehicles, especially container trucks, follow closely behind you. When overtaking, increase speed—never slow down during the maneuver. Minimize side-by-side driving time. Always move to the fast lane before overtaking, confirm that the other vehicle won't change lanes, then accelerate past. When overtaking large vehicles, do so quickly and use high beams and the horn as a warning.

What are the reasons for the engine warning light in Changan CS35?

The engine warning light may illuminate due to the following 7 main reasons: Sensor malfunction: Sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors may be damaged, have poor contact, or experience signal interruption. When the car's ECU cannot accurately obtain engine data, the engine warning light will illuminate. Fuel quality issues: If fuel or engine oil is not added according to the manufacturer's requirements, it may cause engine wear and trigger the warning light. Poor combustion of the air-fuel mixture: Poor combustion can lead to engine carbon deposits or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as a warning. Issues such as spark plug failure, ignition coil failure, fuel pump failure, or fuel line blockage can cause poor combustion of the air-fuel mixture. Turbocharger issues: Problems with the intake turbo pipeline or turbocharger can also cause the engine warning light to illuminate. The most common issue is turbocharger damage, accompanied by symptoms such as oil leakage, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake issues: If the car's intake system has problems, it may lead to engine pipeline blockage, and in severe cases, the engine warning light will illuminate. A dirty air filter that is not cleaned regularly can cause intake problems. Exhaust issues: Exhaust system failures can also trigger the engine warning light. Common causes include rear oxygen sensor failure, catalytic converter issues, exhaust camshaft and bearing failure, with the catalytic converter being the most frequent culprit. Using leaded gasoline, lead or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions can easily cause catalytic converter issues. Anti-theft system malfunction: If the car's electronic anti-theft system fails or the anti-theft controller does not match the engine electronic controller, the anti-theft system can prevent the engine from operating normally, and the engine warning light will illuminate. If the engine warning light is on, follow these steps: First, check if the engine is running normally. Look for symptoms such as shaking or black smoke. If present, avoid restarting the engine. Note: Do not restart the engine if the red warning light is on. If the engine can be started, turn it off and wait for 5-10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the "ON" position without depressing the clutch. The car will enter self-diagnosis mode after powering on. Wait for 5-10 seconds and observe if the warning light turns off. If the warning light remains on, visit a service center as soon as possible. The service center can use a portable diagnostic tool to read the fault code, identify the issue, and perform targeted repairs.

How often should an electric vehicle be charged?

Electric vehicles generally need to be charged every 150-200 kilometers of driving. During the charging process, the temperature of the electrolyte should be frequently measured. Methods such as reducing the current by half, stopping charging, or cooling should be used to control the temperature between 35-40 degrees Celsius. If the specific gravity of the electrolyte does not meet the required standards after the initial charge, adjustments should be made using distilled water or an electrolyte with a specific gravity of 1.4. After adjustment, charge for another 2 hours until the specific gravity meets the required standards. Currently, the popular pure electric vehicles in China have a range of 150-200 kilometers per charge (theoretical value), while some imported vehicles can achieve a range of over 500 kilometers. Different new energy electric vehicles have varying charging times. Precautions for charging electric vehicles: Avoid overcharging or over-discharging the battery: During the charging process, it is essential to control the charging time reasonably to avoid overcharging. Overcharging can cause the battery to overheat, which may lead to dangers such as spontaneous combustion or explosion. While driving, it is necessary to monitor the battery level. If the battery indicator shows the red zone, the driver should stop driving and charge the vehicle as soon as possible. Driving with insufficient battery power can significantly increase the battery's wear rate. Recommend daily charging: Many people struggle to grasp the appropriate charging frequency for electric vehicles. For short distances, charging every two to three days may suffice. However, it is recommended that drivers charge their vehicles daily. This practice keeps the battery in a shallow cycle state, which is more conducive to extending its lifespan and benefits the driver. Pay attention to the charging plug: If poor contact is observed in the charging plug during the charging process, it should be addressed promptly to avoid overheating. Prolonged overheating of the plug can lead to a short circuit, which may damage both the charger and the battery.
