Weilai Vice President Zeng Shizhe talks about ternary iron-lithium batteries: The solution is difficult to copy, and the most difficult part is the control algorithm

Zeng Shizhe: After switching, some competitors’ charging speeds are affected because the electrical conduction path becomes relatively longer. But we are different. We considered this issue when designing. Now charging is actually faster than before. Our measured data has increased by about ten minutes. Of course, the user end may be different. This is related to the actual charging scenario, such as the maximum power of the charging pile, but it has actually increased. The maximum power is up to 1.8C. In fact, this was considered to keep up with the times when it was designed from the beginning.

Question: I would like to ask why our new technology is not applied to 100-degree batteries?

Zeng Shizhe: In fact, some new technologies such as DCDC are planned to be applied to 100kWh, but now it is difficult to arrange 100-degree batteries in terms of overall density. We think each has its own strengths. 100 degrees has its own advantages. There is still room for growth if we go up from 100 degrees. Of course, other solutions are also needed, and we are also studying them. When this thing becomes more mature and iron-lithium is improved again, we will move forward.
