What are electric scooter batteries and what do they do?

The battery is one of the most important components of an electric scooter. They come in a variety of shapes and sizes, but all perform the same basic function: to store energy and provide power to the electric motor. Not all batteries are created equal. Some batteries are better suited for certain applications than others.

There are many different types of electric scooter batteries available on the market, but most of them fall into one of two categories: lead-acid or lithium-ion.

How to choose the right lithium battery for e-scooter?

The first step in choosing the right electric scooter battery for your needs is to determine the voltage you need.

The next step is to determine the capacity of the battery you need.

Once you’ve determined the voltage and capacity of the battery you need, it’s time to contact a reliable battery manufacturer for a battery that meets your needs.

Electric scooter batteries types

Lead-acid batteries

Lead-acid batteries are the type of electric scooter battery and they come in two main varieties: flooded lead-acid and sealed lead-acid.

Flooded lead-acid batteries are the older type of battery and they require periodic maintenance to keep them in good condition. Sealed lead-acid batteries are newer than flooded lead-acid batteries and don’t need any maintenance. They are also safer because they can’t spill acid if they are damaged.

Lead-acid batteries have a lower cell voltage (2V) and a lower energy density than lithium-ion batteries. They also have a shorter lifespan (usually around 300 cycles). However, they are cheaper than lithium-ion batteries.

Lithium-ion batteries

The Li-ion batteries are the lightest on the market, which makes them very attractive to electric scooter manufacturers. 

Lithium-ion batteries have a higher cell voltage (3.6V) and a higher energy density than lead-acid batteries. Moreover, they have a longer lifespan (usually around 500 to 800 cycles).

Lithium-ion batteries are the most popular type of electric scooter battery and they come in two main varieties: NCA and NCM.

NCA – Nickel-cobalt-aluminum

Triple elements – Ni, Co, Al 

Advantages:

  • Highest power density and energy density
  • Good cycle life
  • Low self-discharge

Anode –  LiNixCoyAlzO2

Cathode – Graphite + Si

NCM – Nickel-cobalt-manganese

Triple elements Ni, Co, Mn

Advantages:

  • High power density
  • Long cycle life
  • Low cost 
  • Balance

Anode –  LiNixCoyMnzO2

Cathode – Graphite

NCM18650        150Wh-220Wh/KG

There are also batteries such as lithium iron phosphate and nickel-metal hydride batteries, but they are not as often used as the previous options.

Cell Manufacturer

There are many different cell manufacturers which are suitable for electric scooter batteries on the market, but some suppliers are more popular than others.

Typical manufacturers and materials for electric scooters include:

Chinese typical big players: CATL, BYD…

NCM cells manufacturers: LG, SAMSUNG, CATL, and others

NCA cells manufacturers: LG, SAMSUNG, Panasonic, CATL, and others

Battery Packs

Most electric scooters come with a battery pack consisting of two or more individual batteries. The battery pack is made up of individual cells that are connected in series and/or parallel to create the desired voltage and capacity.

Voltage

The voltage of an electric scooter battery pack is determined by the number of cells in the pack and their voltage rating. The voltage of an electric scooter battery pack is usually between 24V and 48V.

When fully charged, each cell in the battery pack will have a voltage of 4.2 volts however, the standard voltage of each cell is 3.6 volts.

Capacity Ratings

Capacity ratings are a measure of how much energy a battery can store. The higher the rating, the more energy the battery can store.

The capacity of an electric scooter battery pack is usually expressed in amp-hours (Ah). A higher Ah rating indicates a larger capacity. For example, a 12-volt, 15-Ah battery pack can store up to 180 watt-hours of energy. The battery capacity is usually between 9Ah and 30Ah.

Battery Life

Electric scooter battery life is typically between 300 (for lead-acid battery) and 500 (for lithium-ion battery) charge cycles. This means that they can be charged and discharged a total of 300 to 500 times before they need to be replaced.

C-rate

C-rate is a measure of how fast a battery can be discharged. It is expressed in terms of the capacity of the battery. For example, a battery that has a C-rate of one means that it can discharge its rated capacity in one hour.

Most electric scooter batteries have a C-rate between 0.5 and two.

Battery Management System

Most modern electric scooters have built-in battery management systems – providing battery protection. The BMS is responsible for monitoring the condition of the battery and making sure that it is never overcharged or discharged. It also protects the battery from excessive heat and short circuits.

Most BMS systems will cut off power to the battery when it reaches a predetermined voltage or Ah rating. This prevents the battery from being damaged and allows it to be used safely in an electric scooter.

The functionality of BMS allows not only to improve the operating mode of rechargeable batteries but also to maximize their lifetime.

Tips for extending the life of your lithium battery for e-scooter

There are a few things you can do to help extend the life of your lithium battery for e-scooter. Follow these tips and you’ll be able to get the most out of your battery:

  • Don’t let your battery run completely flat. Try to avoid letting the battery level drop below 20%. This will help keep the cells healthy and extend their lifespan.
  • Avoid extreme temperatures. Don’t leave your battery in direct sunlight or in freezing cold weather conditions. This can damage the cells and reduce their lifespan.
  • Keep your battery clean. Dirt and dust can build up on the cells over time, which can affect their performance.

These tips should help you get the most out of your electric scooter battery and keep it in good condition for longer.

Troubleshooting tips for common problems with lithium battery for e-scooter

If you’re having trouble with your electric scooter battery, don’t worry – we’ve got you covered. Here are some of the most common problems and their corresponding solutions:

  • Your electric scooter isn’t holding a charge: This could be due to a number of factors, including a damaged battery, a defective charging port, or a malfunctioning BMS. Try cleaning the ports and connectors with a soft cloth.
  • Your electric scooter won’t start: This could be due to a number of factors, including a dead battery, a defective switch, or a disconnected cable.
