Overview
IEC TS 62840-1:2016 - Electric vehicle battery swap system - Part 1: General and guidance - provides a high-level, practical framework for battery swap systems used to replace swappable batteries of electric road vehicles (EVs). It applies when the vehicle powertrain is turned off and the swap system is connected to supply voltages per IEC 60038 (rated up to 1 000 V AC and 1 500 V DC). The Technical Specification covers systems that handle one or more swappable battery systems (SBS) and serves as generic guidance; detailed safety requirements are addressed in IEC 62840-2.
Key topics
- System overview and architecture
- Definitions and functional breakdown of a battery swap system and a battery swap station (BSS).
- Battery swap station components
- Lane system, battery handling system, storage system, charging system, and supervisory & control system.
- Zones and interfaces
- Guidance on vehicle lane zone, battery swap zone, battery storage zone and battery charging zone, and their accessibilities.
- Classification
- Automation levels (full automatic, semi-automatic, manual), SBS swapping direction, EV categories, and environmental conditions.
- Use cases and solutions
- Informative annexes include use cases (positioning, swapping, charging, maintenance, emergency charging) and example station layouts (side-swapping, top-swapping, bottom-swapping, rear-swapping).
- Scope and exclusions
- Applies to electric road vehicles with swappable batteries; excludes trolley buses, rail vehicles, off‑road‑designed vehicles, and detailed station/vehicle maintenance processes.
Practical applications
Who uses IEC TS 62840-1:2016:
- EV OEMs and battery manufacturers designing swappable battery systems (SBS) and vehicle interfaces.
- BSS designers, system integrators and charging network operators planning battery swap stations and layouts.
- Urban planners and fleet operators (taxis, buses, delivery fleets) evaluating fast energy replenishment strategies to reduce range anxiety.
- Test laboratories and conformity assessment bodies referencing architecture and use case guidance.
- Policymakers and industry stakeholders developing interoperability and grid-connection strategies.
Practical benefits:
- Speeds design of interoperable battery swap solutions.
- Helps reduce vehicle downtime by defining swap processes and automation levels.
- Minimizes grid impact by enabling off‑vehicle charging and centralized SBS management.
