What are the effects of charging a children's electric car for more than 12 hours?
2 Answers
Charging a children's electric car for more than 12 hours poses certain safety hazards, with the following specific effects: Impact on the battery: When the charging voltage matches the battery voltage, it enters the so-called "trickle" charging phase. This process is crucial for fully charging the battery, but it also has the lowest electrical efficiency and consumes power. Since this process continues to charge, if affected by temperature or unexpected factors, fluctuations in charging voltage may occur, breaking the balance and potentially causing the battery to "overcharge." Impact on driving experience and safety: Frequently charging for more than 12 hours, or even forgetting to disconnect the power for over 20 hours, can affect the usability of the electric car and may lead to spontaneous combustion, endangering the driver's safety.
As a parent, I'm quite concerned about children's electric toy cars being charged for over 12 hours. Once, I forgot to unplug my son's car after charging, and the battery became so hot it burned to touch, later developing a bulge. After that incident, the car could only run for a few minutes before completely failing. Lithium batteries are most common in these toys, and overcharging can degrade internal materials, raise temperatures to dangerous levels, and even cause fires; lead-acid batteries are slightly better but still prone to swelling and shortened lifespan. Safety-wise, this is definitely a major hazard—I've seen news reports of similar situations causing house fires, so it's crucial to address it promptly. I've since developed the habit of charging for only 6-8 hours and setting a phone alarm to remind myself to unplug it. I recommend parents choose chargers with auto-shutoff features, read the instruction manuals carefully, and prevent children from tampering with them. Additionally, regularly checking the battery for signs of aging is important. Overall, protecting children and family safety is far more important than cutting corners.
