Abstract

The invention discloses a charging device for the storage battery of an electric locomotive, and a charging method, wherein the charging device comprises an AC power supply, a monitoring system, sensors, a plurality of AC/DC modules, and a storage battery and further comprises a filtering device and an over-voltage protection device, wherein the sensors include a temperature sensor and a current sensor, the charging voltage of the storage battery is correspondingly adjusted according to the temperature variation in the environment where the storage battery is located, so that the charging time is effectively reduced, the charging efficiency is improved, the charging requirements of the storage battery can be well met, and the problems that the lead acid storage battery is vulcanized and the capacity is reduced when the environmental temperature is over low, and thermal runaway occurs on the lead acid storage battery and the performance and the service life are weakened when the storage battery is under an over-high environmental temperature are solved.

Description

technical field [0001] The invention relates to a battery charging device and a charging method of an electric locomotive. Background technique [0002] The internal structure of the current locomotive battery charging device is as follows: figure 1 As shown, the battery charging device includes an AC power supply, a monitoring system, several AC / DC modules, sensors, and battery packs. The AC power supply is connected to the AC / DC module, the monitoring system is connected to the AC / DC and the sensor module, and the AC / DC module, The sensor is connected to the battery pack. At present, the battery pack on the electric locomotive uses lead-acid batteries, generally 48 sections. The charging method of the battery pack is formulated according to the standard TB-3061. No matter what capacity the battery pack is in, the charging voltage of the battery pack is the same. It is DC110V and has no temperature compensation function. When the ambient temperature of the battery pack is ...
