What are the reasons why new energy vehicles cannot be fully charged?

This is due to a fault in the power battery system, which prevents it from being fully charged. You should go to a service center for inspection. Below is relevant information about new energy vehicles: Basic Structure: Electric vehicles are mostly automatic transmission models. Structurally, pure electric vehicles rely on the three core components (battery, motor, and electronic control) as the power source. They do not have a traditional transmission system. According to the working principle of pure electric vehicles, they operate by supplying electrical energy from the battery to the motor, which drives the vehicle. Output Characteristics: New energy vehicles generally do not come equipped with multi-speed transmissions. The torque output characteristics of the motor eliminate the need for a "transmission" to coordinate the relationship between speed and torque.

I've been driving a new energy vehicle for almost three years and have encountered the issue of incomplete charging several times, mainly due to battery aging or environmental factors. Over time, battery capacity decreases, much like how a smartphone battery's lifespan shortens, causing charging to stall at a certain point. Temperature plays a crucial role. High temperatures in summer can trigger the battery to automatically limit charging to prevent overheating, while cold temperatures in winter reduce battery activity, affecting charging efficiency. I recommend charging in moderate environments, such as indoor garages or shaded areas, to avoid exposure to extreme weather. Regularly checking the battery's health status is essential. Using onboard diagnostics or professional scanning tools can help detect issues early. Charging habits also matter. Avoid frequent full charges or deep discharges; maintaining the battery level between 20% and 80% can extend its lifespan. Choosing the right charging station is also important. If public chargers are outdated or incompatible, they may not charge fully—trying a different one might help. Proactive maintenance can save a lot of trouble.

As a new energy vehicle owner, one of the common reasons for not being able to fully charge is charging equipment failure. If the voltage is unstable or the wiring is damaged in a home charging station, the charging power will drop, preventing a full charge. Public fast-charging stations also frequently encounter issues, especially when the model is incompatible, leading to slower speeds. I've experienced poor plug contact multiple times—loose charging ports or dust buildup can interrupt current transmission. Check your home circuit to ensure the wires are thick enough and not aged, and turn off high-power appliances during charging. Software updates for the onboard charger are also essential, as manufacturers often optimize the system to improve compatibility. For safety, ensure the charging environment is well-ventilated to avoid heat buildup and potential risks. Regularly clean the charging port and have a professional inspect the overall wiring periodically. These steps can reduce unexpected charging interruptions. Try reliable charging station brands like TELD or Star Charge for better results. These small tips can improve your experience and save time.

I've found that new energy vehicles often fail to charge fully due to software or setting limitations. For instance, the battery management system automatically throttles charging to 80% when the battery is low or temperatures are too high, to protect battery lifespan—much like a smartphone's protection mode. Checking your vehicle's menu might reveal adjustable charging limit options. Outdated software can also cause issues, as new firmware frequently includes bug fixes. In my case, restarting the charging system sometimes restored full charging capability. Regularly updating firmware and following the manual's recommended settings can prevent such limitations. Addressing these issues early prevents minor faults from snowballing into major problems.
