Open Standards/Multipurpose AC-Battery/Mechanical specification

This chapter describes the mechanical requirements and definitions for a multipurpose AC-battery pack. Requirements: The mechanical construction has to fulfill the following requirements: - All the accumulator packs have the same defined length and width. They shall be useable in e-Bikes as well as in electric vehicles. - There are three variants in height. - All sizes shall fit on the same holder and connector. - They shall have a carry / fix / release handle with comfortable diameter and sufficient space for the fingers. - The accumulator packs shall have small wheels at the connector side to ease insertion. - The ground plane common to all sizes has to be flat and support heat sinking. - The weight shall not exceed the weight of a six pack of coke bottles (12Kg). - The accumulator packs shall withstand rain Specification: Dimensions: All battery packs shall have an overall length of 360mm without the handle. border|800px All battery packs shall have an overall with of 100mm exclusive the handle arms and fixation and w with of 105mm inclusive the handle arms and fixation. The fixation and the insertio wheels shall have a with of 2mm on each side. A tongue and grouve ring is used to make the connection side waterproof. The connector side is symmetrically. There are three sizes of AC batteries: small (50mm), medium (100mm) and large (200mm). border|bottom|250px border|250px|bottom border|250px Connectors: For power connection there are two female ring contacts inside with a diameter of 10mm. They shall have the ability to carry up to 300A continuous current and insulation for 3000V. For control connection, there are 3x3 female connectors inside. type: "PHOENIX CONTACT - 1792760 - PLUG, FREE, 5.08MM, 3WAY" (better suggestions welcome). Current rating: >0,1A, insultion voltage: 3000V. border|bottom|800px Connection right side: Power pole MINUS if positive voltage is requested. Upper pin : RX data from control unit (or previous battery pack) Intermediate pin: Signal ground for RX data and marker Lower pin: Input Marker from control unit (or previous battery pack) Connection left side: Power pole PLUS if positive voltage is requested. Upper pin : TX data to next battery pack (or control unit) Intermediate pin: Signal ground for TX data and marker Lower pin: Output Marker to next battery pack (or control unit) Connection in the middle: Upper pin : Input command signal from control unit Intermediate pin: Signal ground for trigger and command signal Lower pin: Input trigger signal from control unit
