Introduction
Pluggable energy storage technologies have a number of needs and prospects in certain areas. Energy storage list for electric vehicles and renewable energy
The emergence of meta and other applications requires specification to ensure safe and reliable operation, interchangeability, environmental protection and energy efficiency. Industry needs
It is expected to promote technological development and popularize pluggable energy storage technologies.
There are some special points to consider compared to other accessory products. The docking process may not be able to find the connector by human manipulation.
The correct position of the two parts. The docking process may have mechanical feed that will prevent the correct position of the two parts of the connector from being found. To overcome these questions
The accessory design can include partially movable parts to compensate for mechanical feed and tolerances.
