Abstract
The invention provides a battery monitoring system comprising a battery monitoring device and at least one battery pack in storage. The battery pack comprises at least one battery core, a controller, and a temperature sensor. When the controller of the battery pack senses that a temperature of the battery core is higher than a safe temperature value, it issues an alarm signal, and directly transmits the alarm signal to the battery monitoring device in a short distance wireless communication, or transmits the alarm signal to the battery monitoring device via a multi-hop transmission of multiple battery packs in the short distance wireless communication. The alarm signal received by the battery monitoring device will be displayed on an alarm notification unit. Accordingly, the battery monitoring system can instantly monitor the temperature of the battery pack in storage to reduce the probability of burning or exploding of the battery pack.
