2022/07/25In recent years, under the influence of carbon emission pressure, the policy support for new energy vehicles in various countries has continued to strengthen. The share of new energy vehicles in the overall automotive market has been increasing year by year. The most important component of new energy vehicles is the power battery, so the market competition for lithium batteries is becoming increasingly fierce. Power batteries are composed of individual battery cells, so quality control is necessary for each cell.
Today, we will introduce the application case of Yishi Technology's LVM series cameras in the lithium battery industry!
