Why is it easy to lose power in the small battery of new energy vehicles?How should it be solved?
In recent years, with the popularization of new energy vehicles, the problem of power loss of small batteries has gradually attracted people's attention. Have you ever encountered an embarrassing situation where your vehicle has difficulty starting, or even not starting at all?
This is likely to be related to the loss of power in the small battery of new energy vehicles. Why is it easy for small batteries to lose power, and how to solve this problem?
The small battery loss of new energy vehicles is a headache for car owners.
Whenever we drive this high-tech futuristic vehicle, but suddenly find that the vehicle can't start, does it make you feel a little confused?So, what exactly is the reason for this?
Let's unravel this mystery together.
Why is it easy for small batteries to lose power?
Different from traditional fuel vehicles, new energy vehicles use two sets of electrical systems: high voltage and low voltage.
Among them, the small battery is located in the low-voltage electrical system, which mainly supplies power to the vehicle's low-power electronic equipment, such as the starting system, door unlocking, etc. However, the reasons why small batteries are prone to power loss are complex and diverse.
First of all, the system settings of some models lead to the fact that the high-voltage battery will only supply power to the small battery when the car is started, and the power supply will be stopped when the car is turned off.
Therefore, when the owner charges in the flame-off state, he will only charge the high-voltage battery, and cannot replenish the power of the small battery, resulting in a loss of power for the small battery.
Secondly, even in the off-vehicle state, some electric vehicles may not be able to continuously charge small batteries while charging.
In the process of charging a gun, even if the charging gun is still plugged in after the charging is completed, the vehicle will no longer continue to charge the small battery, which makes the small battery fall into an embarrassing cycle between power supply and power loss.
Finally, in extreme cases, when the power supply of the small battery is very low, the path of the DC-DC converter may not be able to maintain the contact closed, resulting in the high-voltage battery not being able to replenish the small battery, making it unable to provide enough power when needed.
How should it be solved?
In view of the problem that small batteries are prone to power loss, car owners can take some measures to avoid potential risks.
First, pay attention to your vehicle's system settings.
Knowing whether the vehicle can charge the small battery in the state of being off, and whether it will continue to charge the small battery when the gun is plugged in for charging, is the key to avoid the power loss of the small battery.
Secondly, charge regularly and avoid plugging the gun for too long.
Even for new energy vehicles, it is necessary to maintain the appropriate power of small batteries to prevent power loss caused by long-term shutdown.
In addition, pay attention to the charging state of the vehicle to ensure that the small battery is fully replenished when the gun is charged, rather than being limited to a full charge during the charging process.
The problem of power loss of small batteries highlights some challenges in the technology and system design of new energy vehicles. From system settings to charging strategies, they all need to be smarter and more user-friendly.
For car owners, timely understanding of the performance and system settings of their vehicles, and maintaining the regularity of charging Xi are effective ways to avoid the problem of power loss of small batteries.
At the same time, automakers should also strengthen the optimization of small battery management systems in design and production, improve user experience, and promote the further development of the new energy vehicle industry.
In the future of new energy vehicles, the problem of power loss of small batteries is expected to be solved through the continuous progress of science and technology and the joint efforts of the industry.
With smarter system design, user-friendly settings and clear charging strategies, we believe that small battery deficits will gradually become a thing of the past, providing car owners with a more convenient and reliable driving experience.
