The invention relates to a battery protection system and an electric vehicle, the battery protection system comprises a current collector, an active protection device and a battery management system, the current collector is configured to collect a current value of a main loop, the active protection device is connected to the main loop, the active protection device has a connection state and a disconnection state, and in the connection state, the active protection device is connected to the main loop. The main loop is a passage; in the off state, the main loop is open; the battery management system is in signal connection with the current collector and the active protection device, the battery management system is configured to compare a current value collected by the current collector with a preset current value, and when the current value collected by the current collector is larger than or equal to the preset current value, the active protection device is started; sending a signal for enabling the active protection device to enter a disconnected state to the active protection device; and when the current value collected by the current collector is smaller than a preset current value, a signal for enabling the active protection device to enter a connected state is sent to the active protection device. The electric vehicle comprises the battery protection system.
本公开涉及一种电池保护系统和电动车,其中电池保护系统包括电流采集器、主动保护装置和电池管理系统,电流采集器被配置为采集主回路的电流值,主动保护装置连接于主回路上,主动保护装置具有连通状态和断开状态,在连通状态,主回路是通路;在断开状态,主回路是断路;电池管理系统与电流采集器和主动保护装置信号连接,电池管理系统被配置为将电流采集器所采集的电流值与预设电流值进行比对,并在电流采集器所采集的电流值大于或等于预设电流值时,向主动保护装置发出使主动保护装置进入断开状态的信号;以及在电流采集器所采集的电流值小于预设电流值时,向主动保护装置发出使主动保护装置进入连通状态的信号。电动车包括电池保护系统。
