As shown in fig. 10, this figure is a schematic view of a charging effect of another lamp panel provided in the embodiment of the present application. As shown in fig. 10, the R1-Rn sector represents the right gun charging state, which is equivalent to equally dividing the battery level n, lighting the sector R1 when the battery level is lower than (100/n)% and lighting the sectors R1 and R2 when the battery level is between (100/n)% and (100 x 2/n)%. By analogy, all sectors are fully lit when the battery SOC reaches 100%.

Further, the charging effect in the embodiment of the present application may also be a gradual overlapping effect.
