Overcharging and Discharging of Power Batteries
----SENKU MACHINERY
Power batteries are critical components in new energy vehicles, directly impacting the vehicle's performance and lifespan. Both overcharging and over-discharging can degrade battery performance and introduce safety risks.
What is Over-charging?
Overcharging occurs when the voltage or charge of a battery exceeds its designed maximum value during charging. This can happen due to a malfunction in the charging device or battery management system, or through user error. Overcharging increases the internal pressure and temperature of the battery, potentially leading to thermal runaway. This not only diminishes battery performance and lifespan but also poses significant safety risks, such as explosions.
Preventing Overcharging:
Regularly check charging equipment to ensure it operates correctly and has proper settings.
Follow the manufacturer's recommended charging methods and durations to avoid prolonged overcharging.
Use smart EV chargers equipped with overcharge protection features.
What is Over-discharging?
Over-discharging occurs when the voltage or charge of a battery drops below its designed minimum value during discharge. This can happen when the battery is overused without timely recharging or when the device is overloaded, causing excessive discharge in a short time. Over-discharging leads to irreversible chemical changes inside the battery, affecting its capacity and performance, and can even render the battery unchargeable.
Preventing Over-discharging:
Plan charging schedules to ensure the battery has sufficient charge before use.
Avoid prolonged continuous use of the device, allowing the battery adequate rest time.
Recharge the battery promptly when its level falls below a certain threshold to prevent excessive discharge.
By following these guidelines, you can help maintain the health and safety of your power batteries, ensuring optimal performance and longevity.
