Introduction
Battery swapping is one of the important ways to replenish energy for pure electric
commercial vehicles. QC/T 1201 Compatibility of on-board swappable battery system
for battery electric commercial vehicles series of standards aims to standardize the
interchangeability of on-board swappable battery systems for pure electric commercial
vehicles, thereby achieving interchangeability between vehicles, swappable battery
systems and battery swap stations. This series of standards is intended to consist of 5
parts.
- Part 1.Battery swap coupler. The purpose is to standardize the electrical interface
of the swappable battery system, including the basic requirements for battery swap
electrical connections, signal definitions, contact coupling sequence, connection
interface, terminal arrangement, dimensional parameters.
- Part 2.Battery swap cooling interface. The purpose is to standardize the battery
swap cooling interface, including the basic performance requirements of the
cooling interface, the structure and dimensions of the cooling interface assembly,
the battery end, the vehicle end.
- Part 3.Power swapping mechanism. The purpose is to standardize the mechanical
interface forms and dimensions such as the gripping interface, bearing surface,
guide positioning, locking, etc. of the battery swap battery system, as well as the
installation position of the electrical interface and cooling interface, to ensure the
gripping performance, guide positioning capability, locking capability of the
battery swap battery system, thereby achieving the interchangeability of the
swappable battery system in terms of structural form.
- Part 4.Swappable battery systems. The purpose is to standardize the swappable
battery system, including the general requirements, structure, and size of the
swappable battery system.
- Part 5.Communication between vehicles and battery systems. The purpose is to
achieve barrier-free communication between vehicles from different manufacturers
and batteries from different manufacturers after swapping, by specifying high-
voltage architecture, power-on and power-off logic, interactive signals.
