The invention provides a train storage battery charging detection and alarm circuit. The train storage battery charging detection and alarm circuit comprises a current acquisition circuit used for acquiring charging current when a storage battery is charged; the input end of the current control circuit is connected with the output end of the current collector, and the collected current is compared with a preset current to generate a current control signal; the voltage acquisition circuit is divided into a high voltage acquisition circuit and a low voltage acquisition circuit, and the charging voltage of the storage battery is subjected to voltage division calculation and is compared with preset low voltage and high voltage to generate a voltage control signal; the temperature acquisition circuit compares the acquired current temperature of the storage battery with a set temperature to generate a temperature control signal; the alarm locking circuit locks the storage battery charging circuit when any signal is abnormal. According to the invention, the storage battery can be disconnected from charging and locked when any parameter changes in the charging process of the train storage battery, so that the safety and reliability of the storage battery during charging are ensured, the safety faults such as fire and explosion during charging of the storage battery are avoided, and the safety and reliability of the train during operation are improved.
