Document Information 1.1 Purpouse The purpose of this document is solely to give general guidelines for the installation of CPAC-1054 (CICU) in buses supplied by Volvo Bus Corporation (VBC). It does not replace the more specific instructions needed for the installation of CPAC-1054 (CICU) as part of the assembly instructions needed for different types of buses including all equipment and functions. This latter type of document is written by the manufacturing entity of each type of bus or bus family. Note 1: Since the use of the CPAC-1054 (CICU) is bus specific there is no general “User Manual” for CPAC-1054 (CICU). 1.2 Revision History Rev Date Name Description A 2016-06-14 L-G Sundin First external version A2 2016-06-20 L-G Sundin Minor correction: antenna interface connector (SMC> SMB) A3 2016-06-20 L-G Sundin Use of antenna frequency bands clarified B 2016-07-06 L-G Sundin Max output power corrected to 15 dBm (conducted) C 2016-12-06 L-G Sundin General clean-up.

BB2 Title: Revision: Classification: Page: CPAC-1054 (CICU): General Guidelines - Installation and Operation D Open within project 4(11) 2. Overview Electrical prototype bus at charging station. WLAN/WiFi antenna of the charging station – similar to that of the bus – can be noted immediately to the left of the pantograph upper mounting in the tower. The CPAC-1054 (CICU) is installed in VBC buses for electrical charging control and subsidiary functions of electrical or electrical hybrid busses at charging stations. It is not intended for any other use. The CPAC-1054 (CICU) communicates via a WLAN/WiFi connection for Hi-Power charging (HPC) and via a cable for Low-Power (“overnight”) charging (LPC). The communication is regulated by the ISO 15118 standard. This document focuses on general aspects of the WLAN/WiFi communication. The WLAN/WiFi connection is solely used for M2M communication between the bus and the charging station. WLAN/WiFi is used for the movement control of the tower mounted pantograph and for handling the charging sequence. No human action is required or used for the WLAN/WiFi communication between the charging station and the bus. The connection is not used for voice - or - general purpose data transfer not related to the basic charging and associated functions. The WLAN/WiFi function of the charging station pantograph tower has a master role in the communication, while the WLAN/WiFi function of the bus has the client/slave role. The WLAN/WiFi communication is done in the vertical plane and can only be performed when the bus and the bus antenna is positioned underneath the antenna of the charging tower. The WLAN/WiFi communication may have a function related to the positioning of the bus with respect to the pantograph, but this is often handled by other means. To support positioning operations, similar hi-gain antennas1 are used in both the charging station tower and the bus. 1 The hi-gain property of the antennas as such, is not used by the system, but the antenna lobe property with confined sharp flanks in (or close to) the antenna near field is.
