What are the specific requirements of the EN standard for the battery of electric scooters?
With the popularity of electric scooters in the international market, more and more wholesale buyers have begun to pay attention to the safety and performance of their batteries. The EN standard, that is, the European standard, puts forward strict requirements for the batteries of electric scooters to ensure the safety and reliability of the products. This article will explore in depth the specific requirements of the EN standard for electric scooter batteries to help wholesale buyers better understand and choose battery products that meet the standards.

Introduction
As a convenient means of transportation, electric scooters are loved by consumers all over the world. However, the safety and performance of their batteries are directly related to the safety of users and the life of the product. As an important entry standard for the European market, the EN standard puts forward detailed technical specifications and safety requirements for the batteries of electric scooters. Understanding and complying with these standards is crucial for manufacturers, wholesalers and buyers of electric scooters.

EN Standard Overview
EN 17128:2020 is a European standard for safety requirements and test methods for personal light electric vehicles (such as electric scooters, electric balance vehicles, etc.). The standard aims to ensure that the design, manufacture, labeling and use of electric scooters meet relevant safety requirements, covering multiple aspects such as batteries, motors, brake systems, body structures, and user operation prompts.

EN standard specific requirements for electric scooter batteries

Battery performance requirements
Battery capacity and voltage: EN standards have certain provisions for the capacity and voltage of electric scooter batteries. Generally speaking, the battery voltage of electric scooters is usually between 36V and 48V, depending on the design and performance requirements of the vehicle. The battery capacity depends on the vehicle's range requirements, and the common capacity range is between 10Ah and 20Ah.
Battery cycle life: The standard requires that the battery should have a certain cycle life to ensure long-term reliability under normal use conditions. Generally speaking, a high-quality lithium battery has a cycle life of more than 500 times, which means that under normal use, the battery can support the vehicle to travel thousands of kilometers.

Battery safety requirements
Electrical safety: The battery must comply with relevant electrical safety standards to prevent overheating, short circuits and other electrical faults. This includes using safe wires and plugs, and being equipped with an effective battery management system (BMS). BMS can monitor the voltage, current and temperature of the battery in real time to prevent the battery from overcharging, over-discharging and overheating, thereby improving the safety of the battery.
Mechanical safety: The structural design of the battery needs to have sufficient strength and durability to withstand various stresses and loads in normal use. For example, the battery casing should have certain impact and vibration resistance to prevent battery damage caused by bumps during vehicle driving.
Thermal safety: The EN standard requires that the battery should have good thermal management performance during use to prevent thermal runaway. This includes the heat dissipation design and temperature protection mechanism of the battery. For example, the battery should have an overheating protection function. When the battery temperature exceeds the safe range, it can automatically cut off the circuit to prevent safety accidents caused by battery overheating.
Fire retardant: The battery and its components should have certain fire retardant properties to reduce the risk of fire. This requires that the battery casing material should have a high flame retardant grade and be able to resist the spread of flames to a certain extent.
Battery identification and user information requirements
Labels and warnings: Batteries and electric scooters should have clear identification, including manufacturer information, model, maximum load, maximum speed, battery specifications, etc. At the same time, there should be necessary warning labels to remind users to pay attention to the safety of battery use, such as avoiding high temperature environments and using original chargers.
User manual: The manufacturer should provide a detailed user manual to explain the correct use of the battery, maintenance requirements and safety precautions. This helps users understand how to properly operate and maintain the battery, extend battery life and ensure safe use.

Battery testing and certification requirements
UN38.3 testing: For the transportation of lithium batteries, the United Nations UN38.3 test is essential. This test is designed to ensure the safety of lithium batteries during transportation, including the thermal stability and mechanical stability of the battery. Only batteries that pass the UN38.3 test can be legally transported internationally.
IEC 62133 standard: IEC 62133 is a safety test standard for lithium-ion batteries, covering multiple tests such as overcharging, over-discharging, short circuit, vibration, temperature cycling, etc. The battery of the electric scooter should meet the requirements of this standard to ensure its safety under various conditions of use.
CE certification: The battery of electric scooters sold in the EU market must pass the CE certification. CE certification is a mandatory certification for EU market access, indicating that the product meets relevant safety, quality and environmental standards. Batteries that have passed CE certification can be legally sold in the EU market and gain the trust of consumers.

Conclusion
EN standards put forward comprehensive and strict requirements for batteries for electric scooters, covering multiple aspects such as battery performance, safety, labeling and certification. These requirements are designed to ensure the safety and reliability of electric scooter batteries and provide users with a safe riding experience. For international wholesale buyers, understanding and complying with these standards and choosing battery products that meet EN standards are the key to ensuring product quality and market competitiveness. At the same time, this can also help buyers avoid legal risks and market losses caused by non-compliance with standards.
