BATTERY SAFETY ALERT SYSTEM

A battery safety alert system includes a detection device and a controller communicatively connected to the detection device. The detection device is configured to detect position information of an engagement mechanism provided at one of a battery and a battery mounting member. A matching mechanism is provided at another one of the battery and the battery mounting member. The engagement mechanism is configured to engage with the matching mechanism to fix the battery to the battery mounting member. The controller is configured to receive the position information, determine whether the engagement mechanism is fully engaged with the matching mechanism based on the position information, and send out alarm information in response to the engagement mechanism not being fully engaged with the matching mechanism.
