For the purposes of this document, the terms and definitions given in GB/T 29246-2017, GB/T 37935-2019, GB T 35273-2020, GB/T 40861-2021 and the following apply.
3.1
charging system
related functional system for charging power batteries in electric vehicle
Note 1: it is also known as in-vehicle charging system.
Note 2: depending on the charging method and technical architecture, the charging system may include one or more on-board controllers [such as Battery Management System (BMS), On-board Charger (OBC), Wireless Power Transfer (WPT)], or other on-board communication control units that integrate related charging functions.
3.2
important data
data recognized as the cause of the risk of the in-vehicle charging system based on the charging function design and risk assessment, including personal sensitive information and important safety parameters
3.3
personal sensitive information
personal information which, once disclosed, illegally provided or abused, will possibly endanger the personal and property safety and easily result in damages to personal reputation and physical and mental health or result in discriminatory treatment
