In-depth Introduction to the Battery Swapping Cabinet
Solution for Electric Motorcycles in Vietnam
I. Introduction: The Frontier of Southeast Asia's Electric Vehicle Transformation
Vietnam, a Southeast Asian country with a population of nearly 100 million and over 60 million motorcycles in possession, is undergoing a profound transformation in transportation energy. As one of the leading electric two-wheeler markets in the ASEAN region, Vietnam's electric motorcycle market is growing rapidly, with sales surging by nearly 100% year-on-year in the first half of 2025, making it the world's third-largest electric motorcycle consumer market. In this transition, the shortage of charging infrastructure has become a key bottleneck restricting the popularization of electric motorcycles. To address this challenge, the battery swapping cabinet solution has emerged as a core infrastructure of Vietnam's electric motorcycle ecosystem, thanks to its high efficiency, convenience, safety and reliability.
This paper systematically analyzes the battery swapping cabinet solution for electric motorcycles in Vietnam from multiple dimensions, including technical principles, policy environment, market status and operation models, aiming to provide a comprehensive reference guide for industry practitioners, investors and relevant policy makers.
II. Market Background and Development Opportunities of Electric Motorcycles in Vietnam
2.1 Electrification Transition of the "Kingdom of Motorcycles"
Vietnam is known as the "Kingdom of Motorcycles", and motorcycles are the primary means of transportation for its people. Ho Chi Minh City, the city with the largest number of motorcycles in Vietnam, bears huge travel demand. However, with rising oil prices, growing environmental awareness and stricter urban management requirements, electric motorcycles are gradually becoming an alternative to fuel-powered motorcycles.
The explosive growth of the electric motorcycle market is driven by multiple factors: the pressure of rising oil prices on usage costs, the promotion of environmental policies, the green transformation of consumer behavior, and the overall rapid expansion of the two-wheeler electric vehicle market. The Vietnamese government plans to restrict the use of fuel-powered motorcycles in city centers by 2030, and this policy expectation has further accelerated the development of the electric two-wheeler and battery swapping market.
2.2 Pain Points of Charging Infrastructure and the Rise of Battery Swapping Mode
The traditional charging mode faces many challenges in Vietnam: long charging time (usually 4-6 hours), insufficient charging facilities, prominent potential safety hazards, and large space occupation, which seriously restrict user experience. Especially in big cities such as Ho Chi Minh City and Hanoi, where the population is dense and living space is limited, the installation of private charging piles is extremely difficult.
The battery swapping mode effectively solves the above pain points with its unique advantages: users only need to put low-power batteries into the swapping cabinet and take out fully charged batteries to complete energy replenishment, and the whole process takes only about 2 minutes, greatly improving convenience. Meanwhile, battery swapping cabinets occupy a small area and are easy to rent and connect to electricity, making them more suitable for deployment in the high-density urban environment of Vietnam.
III. In-depth Analysis of the Technical Architecture of the Battery Swapping Cabinet Solution
3.1 Overview and Working Principle of the Battery Swapping Cabinet System
A battery swapping cabinet is an intelligent device integrating battery replacement, automatic control and Internet of Things (IoT) communication technologies, which solves the range anxiety of electric vehicles by "swapping batteries" instead of traditional "charging". Its core concept is to separate batteries from vehicles to form independent energy units, and realize the rapid circulation and continuous energy replenishment of batteries through a standardized swapping cabinet network.
The workflow can be summarized as follows:
Users identify their identity via mobile APP or QR code scanning.
The swapping cabinet automatically recognizes the user account and battery status.
The system opens an empty slot, and the user puts in the low-power battery.
The system checks the battery information and then opens the fully charged slot.
The user takes out the fully charged battery to complete the swap.
The background system records transaction data and updates the user balance.
The whole process relies on the Battery Management System (BMS) to accurately monitor battery status, including real-time collection and analysis of key parameters such as temperature, voltage, current and state of charge.
3.2 Battery Technical Standards and Chemical Types
3.2.1 National Battery Technical Standards of Vietnam
Vietnam has established a relatively complete technical standard system for electric motorcycle batteries. QCVN 91:2024/BGTVT National Technical Standards for Traction Batteries of Electric Motorcycles and Electric Mopeds issued by the Ministry of Transport of Vietnam is the core mandatory specification in the battery field of the country.
This standard applies to batteries for electric motorcycles produced, assembled or imported in Vietnam, covering various types such as lead-acid batteries, nickel-metal hydride batteries and lithium-ion batteries, including detachable and non-detachable batteries. The main technical requirements include:
Electrical performance requirements: The measured voltage of the battery shall not be lower than the rated voltage with a fluctuation of no more than 15%; the measured capacity of lead-acid batteries shall not be less than 90% of the rated capacity, and that of nickel-metal hydride and lithium-ion batteries shall reach 100% of the rated capacity; lead-acid batteries shall also meet the requirement of high-current discharge for no less than 40 minutes.
Safety performance requirements: Batteries must pass a number of stringent tests such as overcharge, over-discharge, vibration resistance, short circuit, water immersion and drop test, and no potential safety hazards such as leakage, combustion, explosion or rupture shall occur during and within 1 hour after the tests.
Marking and structure requirements: Batteries must be clearly marked with positive and negative poles, with no deformation or cracking on the shell, and the rated voltage and capacity markings must be durable and clear; high-voltage batteries must also be marked with special warning signs.
3.2.2 Mainstream Battery Chemical Types
In the battery swapping cabinet solution, Lithium Iron Phosphate (LiFePO4) batteries have become the mainstream choice in the Vietnamese market due to their high safety, long cycle life and relatively low cost. Taking a 72V 20Ah LiFePO4 battery as an example, it has good thermal stability and a cycle life of more than 2000 times, which is especially suitable for high-frequency charging and discharging in battery swapping scenarios.
Meanwhile, ternary lithium batteries are also used in scenarios with high range requirements due to their high energy density and small size. Battery swapping cabinet systems are usually designed to be compatible with multiple battery types, and automatically adapt to different chemical types through intelligent identification technology.
3.3 Hardware Design Parameters and Structure of Battery Swapping Cabinets
3.3.1 Overall Architecture Composition
A battery swapping cabinet consists of two main parts: hardware equipment and software system. The hardware equipment mainly includes:
