针对新能源汽车电子设备增多导致低压蓄电池馈电风险升高的问题,本文提出一种汽车低压蓄电池紧急补电系统方案。该系统由网关控制器、智能远程通信终端、蓄电池传感器、车身控制模块及车辆控制单元组成,各节点通过CAN/LIN总线与网关实现通信。该方案可与智能补电策略协同实施,可有效降低汽车蓄电池彻底放电的概率,避免永久损伤,提升用户用车体验。

In response to the problem that the increase in electronic devices in new energy vehicles leads to a higher risk of low-voltage battery depletion, this paper proposes an emergency charging system scheme for automotive low-voltage batteries. This system is composed of a gateway controller, an intelligent remote communication terminal, a battery sensor, a body control module and a vehicle control unit. Each node communicates with the gateway through CAN/LIN bus. The solution can be implemented in conjunction with the intelligent charging strategy, which can effectively reduce the probability of complete discharge of the car battery, avoid permanent damage, and enhance the user's driving experience.
