Choix d'un fournisseur de batteries pour motos électriques de 72 V : guide complet à l'intention des acheteurs OEM

The 72V electric motorcycle battery system is commonly used in applications that require higher power output, longer riding range, and stable performance. Compared with lower-voltage systems, a 72V battery pack is often selected for high-power electric motorcycles, delivery vehicles, performance scooters, and commercial mobility applications.

However, choosing a suitable 72V electric motorcycle battery supplier is not only about finding a battery with the correct voltage. The battery pack needs to match the vehicle system, including the motor, controller, charger, installation space, and operating environment.

For electric motorcycle manufacturers and distributors, the battery supplier should have capabilities in:

• Conception du bloc-batterie
• Sélection des cellules
• Développement du BMS
• Personnalisation structurelle
• Tests de sécurité
• Mass production management

A reliable supplier can help reduce integration problems and improve product consistency during long-term production.

Dongguan Yizhan Electronics Technology Co., Ltd. provides customized lithium battery PACK solutions for electric motorcycles, e-bikes, industrial vehicles, and other electric mobility applications.

What Is a 72V Electric Motorcycle Battery?

A 72V electric motorcycle battery pack is a lithium battery system designed to provide approximately 72 volts nominal output.

A typical lithium-ion 72V configuration usually uses:

• 20 series (20S) battery cells
• Fully charged voltage: around 84V
• Different parallel configurations depending on capacity requirements

The final battery specifications depend on:

• Puissance du moteur
• Courant du contrôleur
• Required riding range
• Poids du véhicule
• Environnement d'application

Par exemple :

A 72V system should be designed as a complete power solution rather than simply selecting a higher voltage battery.

Why Choose a Professional 72V Electric Motorcycle Battery Supplier?

1. Battery Design Needs to Match Vehicle Requirements

A professional battery manufacturer evaluates the complete vehicle system before designing the battery pack.

Parmi les paramètres importants, on peut citer :

Puissance du moteur

Higher-power motors require batteries with suitable discharge capability.

Par exemple :

• 1000W motor
• 2000W motor
• 3000W+ motor

may require different battery current outputs.

Controller Compatibility

The battery must match:

• Courant de décharge continu
• Courant de décharge maximal
• Controller protection settings

An incorrectly designed battery may cause:

• Chute de tension
• Accélération réduite
• Activation de la protection BMS

Installation Space

Electric motorcycles have limited battery compartments.

Battery suppliers need to consider:

• Dimensions de la batterie
• Supports de fixation
• Cable position
• Choix des connecteurs
• Waterproof structure

How to Select the Right Battery Cells for a 72V Motorcycle Battery?

Battery cells directly influence:

• Densité énergétique
• Durée du cycle
• Performances en matière de sécurité
• Coût

Parmi les choix courants, on trouve :

Cellules de batterie au lithium NMC

NMC cells are widely used where higher energy density is required.

Avantages :

• Densité énergétique plus élevée
• Compact battery design
• Suitable for lightweight vehicles

Applications :

• Motos électriques hautes performances
• Long-range models
• Urban commuting vehicles

Cellules de batterie LiFePO4

LiFePO4 batteries are often selected for applications requiring stable operation and longer cycle performance.

Avantages :

• Bonne stabilité thermique
• Longue durée de vie
• Suitable for frequent charging applications

Applications :

• Motos de livraison
• Véhicules de flotte
• Commercial mobility solutions

Evaluate the Battery Supplier’s BMS Capability

The Battery Management System (BMS) is a critical part of a 72V electric motorcycle battery pack.

A suitable BMS should provide:

Fonctions de protection

Y compris :

• Protection contre les surcharges
• Protection contre la surcharge
• Protection contre les surintensités
• Protection contre les courts-circuits
• Protection de la température
• Équilibre cellulaire

Smart Communication Functions

For advanced electric motorcycle applications, suppliers may provide:

• Communication CAN
• UART
• RS485
• Surveillance Bluetooth

Smart BMS allows vehicle manufacturers to monitor:

• État de la batterie
• Capacité restante
• Informations sur les pannes
• Conditions de fonctionnement

Check the Manufacturing Process of the Battery Supplier

A professional 72V battery manufacturer should have a controlled production process.

Battery Cell Inspection

Before assembly:

• Test de tension
• Test de résistance interne
• Vérification de la capacité
• Correspondance des cellules

are important steps.

Consistent cells help improve battery pack performance.

PACK Assembly Process

Typical production steps include:

1. Disposition des cellules
2. Welding connection
3. Installation du système de gestion de batterie (BMS)
4. Ensemble de câblage
5. Installation du boîtier
6. Performance testing

For electric motorcycle applications, the battery pack also needs mechanical protection against:

• Vibrations
• Choc
• Poussière
• Humidité

Aging and Final Testing

Before shipment, battery packs should complete testing procedures such as:

• Test de charge
• Essai de décharge
• Test de protection
• Test de communication
• Essai de vieillissement

These processes help verify product consistency.

Certifications and Compliance for 72V Electric Motorcycle Batteries

When exporting electric motorcycle batteries, manufacturers should consider market requirements.

Common documents and certifications include:

UN38.3

Obligatoire pour le transport de batteries au lithium.

It covers safety tests including:

• Simulation d'altitude
• Temperature cycling
• Vibrations
• Mechanical shock

IEC 62133-2

A safety standard for rechargeable lithium battery cells and batteries.

CE et RoHS

Common requirements for products entering European markets.

Règlement de l'UE sur les batteries

Battery manufacturers supplying European customers should pay attention to requirements related to:

• Battery information
