E-Bike Battery: Everything You Need To Know

Electric bicycles, popularly known as e-bikes, have gained popularity now more than ever. They are a more convenient means of transportation that provides pedal assistance, making cycling less exerting. But at the heart of every e-bike lies its battery.

Simply put, the e-bike battery is an essential component that powers the bicycle’s electric motor, determining its range and performance. Let’s take an in-depth look into these power units, covering the basics, the components, and maintenance tips.

Basic Info about E-Bike Batteries: What are They?

An E-Bike battery is a rechargeable cell that generates the power to propel the bike’s electric motor. It stores the energy the motor needs to run and perform essential functions; without a battery, the rider has to rely on pedals alone. The batteries used in these electric motors are usually larger and more powerful than those used in other consumer electronics since they deliver sustained power over longer periods.

In NAKTO e-bikes, the power unit is located on the frame or down-tube, so it can be easily removed for charging. This strategic positioning also allows for easy connection to the motor, which helps generate additional power when pedaling. With this, riders can travel longer distances, tackle steep inclines, and maintain higher speeds with minimal physical exertion.

 

Types of E-Bike Batteries

E-bike batteries are of many types, each with distinct features, but three major varieties exist. These include:

1. Lithium-ion (Li-ion) Batteries:Li-ion power units are the main types commonly used in most electric bicycles in the market, including those from NAKTO. Lithium-ion battery types have the triple benefits of being lightweight, having high energy/power density, and having a long cycle life. They also offer a good power output capacity, low self-discharge rates, and are less expensive than other types.
2. Nickel-Metal Hydride (NiMH) Batteries:NiMH batteries were the most in-demand type in the early stages of electric bicycle production. However, with innovations of Li-ion substitutes, NiMH batteries started to fade out of the market. This battery type provides fair energy density and a good life cycle but is rather bulky and heavy.
3. Lead-Acid Batteries:Lead-acid batteries are heavy, have low energy density, and have very short overall life spans. They were some of the first to be applied, but they quickly became supplanted by their many drawbacks. One disadvantage of lead-acid batteries is that they require frequent maintenance because they have a high corrosive level. Also, they are less efficient and less suitable for modern-day e-bikes.

Electric Bicycle Battery Performance: Nominal and Peak Power

The nominal and peak power of an e-bike's motor and battery plays a significant role in determining its performance.

In simple terms, nominal power is the average power the motor and battery can produce, that is, the level of assistance the motor can provide. A battery with a nominal power of 250W can provide moderate assistance, making it suitable for casual riders. But for those with 500W, it’s more powerful and perfect for off-road riding.

On the other hand, peak power is a measure of the maximum amount of power the battery and motor can deliver in spontaneous bursts. For instance, when accelerating quickly or climbing a steep hill, the battery’s peak power determines its ability to maneuver tough terrain and sudden movements.

 

NAKTO E-Bikes’ Battery Capacity and Lifespan

Capacity

An e-bike’s battery capacity measures the amount of energy it can store; it is the main attribute of any battery. Every electric bicycle’s battery capacity is measured in Watt-hours (Wh). To calculate this, multiply the battery’s voltage by its ampere-hour rating (Ah). Ampere-hour is the measure of the fixed number of amps a battery can sustain for an hour.

Note that the average battery capacity of any bike depends on various factors, such as:

• Rider weight and speed
• Terrain, i.e., flat versus hilly
• Wind conditions or air resistance
• Tire pressure and level of pedal assist used
• Temperature

Lifespan

The measure of the battery's lifespan is denoted as charge cycles, and most modern Li-ion types have a lifespan of 500 to 1000 charges. Only after expending the allowed number of charges does the capacity decrease noticeably. When a rider uses 100% of the battery’s capacity, they’ve completed a charge cycle, but this doesn’t always imply a single charge from 0% to 100%. Thus, the longer the battery gets discharged, the fewer possible cycles one can expect.

However, with proper care, the battery can last up to 3 to 5 years before needing replacement. Riders of NAKTO e-bikes can maximize the power unit lifespan through the following:

• Avoid draining it to its last percentage before recharging
• Store the battery at about 40-60% charge when not used for extended periods
• Keep it away from extreme temperatures
• Use only the charger the manufacturer provides; you can always buy another from them if it deteriorates.
• Don’t overcharge the battery; disconnect it from the power source once fully charged.

Safety Tips for Charging and Maintenance

Charging and maintaining the power unit is crucial to avoid battery failures and possible electric bicycle hazards. Here are some guidelines to ensure your battery remains in prime condition:

Storage Temperature

To prolong the battery's life expectancy, store it in a cool, dry place. This is especially valid if one wants to keep it away for an extended period. Continuous exposure to heat affects the power unit’s performance. As a result, it has to be stored at a certain temperature, from 0°C to 20°C, which is preferable.

Proper Charging Measures

Charging your bike frequently helps maintain the power unit’s capacity. Regular charging also prevents cell degradation if you keep your bicycle stored for a long time. At the same time, never allow the battery to drain completely, nor should you leave it discharged for an extended period.

Furthermore, only charge the cell with NAKTO chargers from the manufacturer or authorized stores. Follow charging guidelines and disconnect the charger once the cell reaches full charge so as not to damage it.

 

Cleaning and Protection

The battery must be kept clean and should not come in contact with dust, dirt, or even water. To clean it, you could use a damp cloth, but make sure the cloth is not dripping wet. Moreover, avoid cleaning the power unit with chemicals or abrasive materials in case they scrape or penetrate the casing or the connectors.

Consider putting protective plastic around the battery to protect it from physical impacts. In addition, different batteries which have been condemned should be disposed of properly at suitable recycling facilities.

 

Routine Inspections

Once in a while, it is advisable to check the electric bike’s battery for damage, such as leakages, contact looseness, cracks, etc. If you are a first-time user, you can watch this YouTube clip to learn what to look for.
