What are the effects of charging a children's electric car for more than 12 hours?
3 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.
I have some knowledge about electronic products. Overcharging a child's electric toy car for more than 12 hours is indeed problematic. When the internal chemical reactions of a lithium battery go out of control, the temperature rises sharply, potentially causing swelling, leakage, or even fire; lead-acid batteries may also experience accelerated electrode degradation. The charger should automatically cut off, but cheap ones often lack sufficient protection—I tested one small car where the voltage spiked after 12 hours of charging, frying the circuit board. Normal charging time is typically 4-6 hours. Overcharging not only wastes electricity but also reduces battery lifespan by 20%-30%, which is counterproductive. I recommend checking the battery type (lithium batteries pose higher risks), using original accessories, and adding external protection devices like timer sockets. Additionally, maintaining a well-ventilated environment to prevent heat buildup can extend the device's lifespan, saving money and ensuring safety. Don’t overlook this small issue—long-term improper charging can quickly ruin the car.
