What are some common mistakes in charging battery electric locomotives?

Nowadays, battery electric locomotives are widely used in mines, so related problems are also endless. Leaving aside some of the problems common to electric locomotives, the unique problems of battery electric locomotives mainly focus on the battery. What is the difference between several types of batteries? How to maintain the battery? Is there anything special about the maintenance of battery electric locomotives? Waiting for many questions, today we will give a brief introduction to the wrong way of battery charging:

The first is to try to use the original charger for charging, instead of buying other brands of chargers at will. Although in theory, the design of batteries and chargers of different manufacturers and models is similar, so it is not impossible to be universal, but subtle differences may ultimately be the culprit of the problem. In addition, even if you can only use chargers from other manufacturers due to reasons such as the manufacturer's discontinuation, try to choose a brand with a good reputation and quality assurance, rather than choose a brand that is cheap. No-brand chargers that fight price wars may use relatively low-quality electronic components, and the production and supervision process may not be in place. After a few uses, the battery may bulge.

The second is to try not to use the so-called fast chargers. The so-called fast charging generally uses high current or high voltage to achieve the effect of fast charging. In this way, although the speed is increased, the high voltage and high current will also aggravate the evaporation of the battery liquid, which will reduce the service life of the battery.

Finally, there is the problem of overcharging. However, today's batteries, especially lithium batteries, are generally equipped with a BMS (battery management system), which will automatically power off when the battery is fully charged to avoid battery damage caused by overcharging. Even if the battery does not have BMS, many chargers on the market have similar systems to avoid overcharging.
