Guide to selection of electronic power supply in jinshengyang (6)-smart balanced charging system solution

Overview:

 

In the previous analysis of electric vehicles, we have simply mentioned that each battery in the battery pack is different and cannot be completely consistent. Therefore, improper handling may damage the battery during the charging process, the service life of the product is seriously affected. The smart charging balancing device can intelligently control the charging current according to the Charging Curve of the battery pack. During the charging process, the battery pack can be balanced and charged, ensuring that each battery can reach the maximum charge voltage at the same time, to the greatest extent, the inconsistency between materials, production, and use of battery cells in the battery pack is solved, which greatly improves the available capacity and service life of the battery pack. Therefore, smart charging devices are widely used in fast charging and balanced charging of urban electric buses and hybrid buses.

 

During the whole vehicle charging process, large current is usually used for fast charging, and the current is as high as 30a, or even higher. When high current and fast charging are close to saturation, if large current is still used for charging, it is very likely to cause damage to the battery. At this time, a series balanced charging device is used, the battery is balanced and the status of each battery is monitored in real time during the balanced charging process to ensure the optimal performance of each battery. In this process, each battery is an independent unit. Once the status of each battery reaches Saturation during the charging process, it can be independently controlled to enable and disable charging, it truly realizes intelligent charging management. The following figure shows the smart balanced charging system:

 

 

Our URB2404LD-3000 constant current output module, not only can achieve stable constant current output, at the same time can achieve intelligent remote control, during the charging cycle, use the Ctrl-foot remote shutdown function of the power supply to turn off the auxiliary power twice each second. Use the off gap to precisely monitor the battery voltage until the battery is fully powered off the auxiliary charging power, in the end, 24 batteries are fully filled.

 

Smart balanced charging device power solution:

 

In the face of the above power demand, our company in the world to launch the automotive balanced auxiliary charging power URB2404LD-3000, the power solution has the following features:
