Description

technical field [0001] The invention relates to the field of rail transit, in particular to a voltage acquisition device with hardware protection function for rail transit. Background technique [0002] The development of lithium battery technology and its battery management system has reached a relatively mature and stable stage in the field of electric vehicles, but its promotion and use in the field of rail transportation is still in a preliminary stage. Compared with electric vehicles, rail transit has a harsher and more complex operating environment, higher battery power and voltage levels, and stricter safety requirements. Therefore, batteries suitable for railway operating environments and meeting railway standards have been developed. The management system is of great significance to the promotion and use of lithium battery systems in the field of rail transit. Contents of the invention [0003] Aiming at the characteristics of the lithium battery and the special ...
