E-bikes are considered a sustainable mode of transportation and are becoming very popular these days. Everything has pros and cons, so electric bikes also have some points that should be noticed. For example, the factor that can cause any type of tragic incident is overcharging.
What is overcharging?
Overcharging occurs when the battery remains connected to the charger for a long time and is exposed to excessive voltage. In this article, we will learn about safeguarding against the overcharging of e-bikes. Following are the consequences through which you can understand this factor.
Consequences
Overcharging an electric bike battery can cause overheating and may catch fire. The electrolytes inside the battery heat up and cause the battery to swell and emit gas. This gas can easily catch fire when contacting any spark or flame. Overcharging can also increase the internal temperature of the battery, which causes thermal runaway.
It is because the battery produces more thermal power than it dissipates. It causes a chain reaction that results in a massive explosion.
● Safety Hazards
Overcharging causes the battery to malfunction, swelling, overheating, or even explosion. It is not only dangerous for the rider but also for the nearby people and land.
● Reduced Battery Life
Overcharging reduces the capacity and life span of the battery. Every time you overcharge, the ability of the battery to store charges faints, resulting in poor performance and range. You cannot cover farther distances with this poor-performance battery.
● Financial Loss
Electric bike batteries are costly. Because of the overcharging failure, you will have to change the battery very soon, and an expensive replacement will be needed.
Preventive Measures
To avoid the above factors, the owner must follow these preventive measures.
● Avoid Prolonged Charging
Keep your battery connected to the charger briefly. Do not connect the charger at night when you cannot disconnect it. When the battery is fully charged, disconnect the charge immediately to reduce the risk of failure.
When the battery remains connected to the charger, its internal temperature will increase. Chemical reactions will take place, which cause the battery to swell, have less life span, and even can cause an explosion. This explosion could be hazardous.
● Use Manufacture-approved Chargers.
Always use the e-bike battery charger provided by the supplier. These chargers are specifically created according to the voltage of the battery. The same voltage chargers can charge your battery efficiently. The third-party charger may damage your battery or may affect its working. So it is better to stick with the provided original charger.
● Read The Manual
Every piece of machinery has a manual; e-bike batteries also have one. Always read the manual carefully and follow the instructions given in them. Read carefully about the charging time duration, voltage, or any other kind of instructions related to charging.
● Optimized Charging Pattern
It is always better to charge your battery before it is completely drained. Always charge your battery regularly at optimal levels for a longer life span and better working. Do not wait for its complete drainage. It will prevent overcharging and will increase your battery life span.
● Investment In Smart Chargers
Always prefer those chargers which come with built-in safety features. These chargers may be expensive but can save your battery in the long run. These chargers monitor the battery voltage and stop charging automatically when the battery is charged. These chargers also have heat sensors, timers to set, and prevention against short circuits.
● Be Aware Of The Temperature.
Always take notice of the temperature of the battery. Do not charge your battery in direct sunlight; it will heat it immediately. High temperature affects the performance of the battery. The optimal temperature range is between 10 to 30 degrees.
● Avoid Overexertion
Do not keep your speed increased for a long time. It will exert strain on the battery, which leads to overheating. Avoid continuous riding on steep paths or at high speed for extended periods. Allow the battery to cool down gradually. It will not affect the efficiency. Always check your tire pressures. The tire pressure also plays a vital role in overheating of the battery. If the pressure is low, your bike motor works hard and results in overheating the battery.
Select the correct gear and always prefer pedals, especially on steep paths, to help your bike. This action saves you from damage and is also suitable for your health.
● Storage Conditions
Pay attention to the temperature of the storage place. Keep your e-bike or its battery in a cool and dry place. Do not store in direct sunlight. Extreme heat or cold conditions can adversely affect the performance and risk of overheating.
● Regularly Inspect The Battery.
Always inspect your battery from time to time. Check your battery for any abnormalities, leakage, swelling, or odor. These may indicate damage. If you notice anything like that, consult the specialist or the manufacturer for assistance.
● Install Heat-reducing Features
Make it possible to use additional heat dissipation features like installing heat sinks and cooling fans to regulate the battery’s temperature. These will help in heat dissipation and will reduce overheating.
Conclusion
It is concluded that one can save the bikes from overheating by following the manufacturer’s instructions regarding the time required to charge, voltage, and charging cycles. Prefer to charge daily as compared to charging your battery once after the complete drainage.
Use heat-dissipating tools to keep your bike at an average temperature. Do not charge or keep your bike in direct sunlight.
