Clean the battery case, check the wiring, measure the specific gravity, and add electrolyte... On September 14, Chen Hao and his team were working in an orderly manner in the battery charging and discharging maintenance room of the Qiqihar North Depot of China Railway Harbin Bureau Group Co., Ltd. are performing battery inspection operations.

Chen Hao, 45, is a foreman of the vehicle and electrical workshop maintenance team of Qiqihar North Depot. As an equipment maintenance personnel, he and his team colleagues are responsible for battery maintenance of operating buses and segment-repaired buses. This season of the year is also the busiest time for them. After a day of work, almost all their clothes are soaked. They have become the guardians of bus maintenance work. "We need to be serious and meticulous in doing this work, and we can't make any mistakes, but it feels very worthwhile to be able to exchange our hard work for the comfort of the passengers." Chen Hao said with a smile.

Passenger car batteries are equipment that provide power for the train control system and emergency lighting. They are called the "heart" of the train. Chen Hao's job is to inspect and repair these batteries to ensure that they are in good condition. "Every inspection must carefully check the voltage parameters. Only if we do this, can passengers have a comfortable and warm riding environment." Chen Hao said while wiping the sweat from his forehead.

Chen Hao is measuring the alkaline battery voltage.

In the huge battery room, nearly a hundred passenger car batteries were lying on the ground quietly charging, with white electrolyte bubbles glowing on the connecting lines on the battery surface.

"The electrolyte in the battery will atomize during the charging process, which will produce some pungent sour smell, so we must wear goggles all year round. The quality of the battery directly affects the safety of the vehicle and affects the passenger's ride. car experience, so we must do our best to ensure that the battery has good performance.”

Although the boxy battery looks small, it is the smallest. They are also sixty pounds, and the largest one is more than 100 pounds. During a day's maintenance, he and his team members had to move at least nearly a hundred batteries, which required a lot of effort on their arms. "Don't look at us thin, we are all muscles." He said jokingly.

Chen Hao and his co-workers have to complete the task of nearly 2,000 batteries every week. Every time they move a set of batteries weighing several dozen kilograms, they are often too tired to stand up; after the batteries are charged, they have to move The battery needs to be rinsed and wiped again, but it is very worthwhile to provide the most perfect quality products to passengers.
