Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of PACK equalizers, and in particular relates to a protective shell of a PACK equalizer. Background Art
[0002] The PACK equalizer is a key device used in the battery management system (BMS), and is mainly used in battery packs composed of multiple battery cells. Its core function is to monitor and balance the voltage, power and other parameters of each battery cell in the battery pack. The PACK equalizer monitors the status of each battery cell in real time. When it detects that the voltage or power difference between the single cells exceeds the set range, it will automatically start the balancing function. It usually adopts active or passive balancing methods. Active balancing is to transfer the energy of the battery cell with high power to the battery cell with low power to achieve energy redistribution; passive balancing is to consume the energy of the battery cell with high power through resistance, so that the power of each single cell reaches a relative balance.
[0003] The PACK balancer is susceptible to external impacts such as collisions and scratches in the use environment, which may damage the internal precision electronic components, causing the balancer to fail to work properly, affecting the balance management of the battery pack, and further reducing the performance and service life of the battery pack.
