Need to Know About Electric Bike Charging

Electrically assisted bicycles are becoming increasingly popular. Whether it’s for touring, commuting, or taking on steep hills, HOTEBIKE are a great companion, as long as you can handle the load.

Although battery life is continually improving, the fear of running out of battery power can be a barrier for many users. However, they can be easily recharged at an electrical outlet using the battery charger provided by the manufacturer, or outdoors at charging stations.

Here are some things you should know about charging your electric bike:

Use the right charger

Always use the charger that came with your electric bike or a charger recommended by the manufacturer. Using the wrong charger can damage the battery or even cause a fire.

Voltage and Amperage: Every electric bike battery has a specific voltage and amperage rating, and the charger must match these specifications. If you use a charger with the wrong voltage or amperage, it can cause damage to the battery or even cause a fire.

Connector Type: Different electric bikes use different connector types for the battery and charger. Make sure the charger you use has the correct connector for your bike’s battery.

Manufacturer Recommendations: Always follow the manufacturer’s recommendations for the charger. They will know the exact specifications needed for your battery and will provide a charger that meets those specifications.

Charge in a dry, well-ventilated area

Fire Safety: Lithium-ion batteries, which are commonly used in electric bikes, can be a fire hazard if they are exposed to extreme temperatures or if they are damaged. Charging the battery in a dry, well-ventilated area away from any flammable materials can help reduce the risk of fire.

Battery Performance: Heat can damage the battery and reduce its overall lifespan. Charging in a well-ventilated area allows the heat generated during the charging process to dissipate more effectively, which can help extend the life of your battery.

Moisture: Moisture is also a concern when charging your electric bike. Charging in a dry area helps prevent any moisture from entering the battery or the charging port, which can cause damage to the battery.

Air Quality: Charging in a well-ventilated area helps ensure good air quality. Lithium-ion batteries can emit small amounts of gases during charging, and proper ventilation can help disperse these gases safely.

Never expose your battery to water

Safety Hazard: Lithium-ion batteries can be damaged or even destroyed if they come into contact with water. This can create a safety hazard, as water can cause a short circuit, leading to overheating, fire, or even an explosion.

Corrosion: Water can also cause corrosion, which can damage the battery and reduce its performance and lifespan. Corrosion can also affect the electrical contacts, which can cause issues with charging or discharging the battery.

Moisture Damage: Even if the battery is not directly exposed to water, moisture can still cause damage. Moisture can enter the battery through small openings, such as the charging port, and cause corrosion or other types of damage.

Water-Resistant vs. Waterproof: Some electric bike batteries and components may be advertised as water-resistant or waterproof. However, this does not mean that they can be submerged in water. Water-resistant means that the battery or component can withstand some exposure to water, but it’s still important to avoid exposing it to water as much as possible.

FAQ on charging an electric battery 
Can the battery be charged to 100%? 

Yes, most electric bike batteries can be charged to 100%, but it’s important to note that some battery manufacturers may recommend not charging the battery to 100% all the time, as it can reduce the battery’s overall lifespan.

Most electric bikes have a lithium-ion battery. You can disconnect it before full charge or charge it to 100%. We’ll give you a quick overview of how it works: it charges in 2 cycles. The first cycle is where the battery charges quickly and restores about 90% of its capacity. Therefore, if you disconnect the battery at this point, it means you have “charged” the best part of the battery.

Do I have to wait for the battery to run down completely? 

No, it’s not necessary to wait for the battery to run down completely before recharging it. In fact, lithium-ion batteries used in electric bikes tend to perform better when they are recharged before they are completely drained.

Don't overcharge your battery

Overcharging can damage the battery and reduce its lifespan. Most electric bike batteries take between 3 and 6 hours to fully charge, depending on the battery capacity and charger.

 Lithium-ion batteries used in electric bikes degrade over time, and overcharging can accelerate this process. This can result in reduced performance and capacity, and ultimately shorten the battery’s lifespan.

Disconnect the charger when the battery is full: Once the battery is fully charged, disconnect the charger to avoid overcharging. Some chargers have a built-in indicator that shows when the battery is full.

Store the battery properly

If you’re not going to use your electric bike for an extended period of time, make sure to store the battery in a cool, dry place, away from direct sunlight and extreme temperatures.

Can you charge the battery of your EV while pedaling?

No, it’s not possible to charge the battery of an electric vehicle (EV), including electric bikes, while pedaling. Electric bikes use regenerative braking to recharge the battery while you’re braking, but they do not have the ability to recharge the battery while you’re pedaling.


The energy used to power the electric motor on an electric bike comes from the battery, and the energy required to pedal the bike comes from your own physical exertion. When you pedal the bike, you’re not generating any electrical energy that can be used to charge the battery.


Regenerative braking works by using the electric motor to slow down the bike and convert some of the kinetic energy of the bike into electrical energy, which is then stored in the battery. However, regenerative braking is not a very efficient way to recharge the battery, and it typically only provides a small amount of energy compared to what’s needed to power the electric motor.

By following these tips and tricks for your electric bike charger, you can ride without any worries and save yourself from the hassle of frequently replacing the charger. These simple steps can help you extend the life of your charger and save you money in the long run. So, take good care of your charger and enjoy a smooth and worry-free ride on your electric bike.
