BYD's sales have rebounded sequentially in April, driven by a record high in overseas shipments. According to a report by CnEVPost, the company's sales have increased significantly, with overseas shipments reaching a new high. This rebound is a positive sign for the company, which has been working to expand its global presence. The increase in overseas shipments is also a testament to the growing demand for BYD's electric vehicles (EVs) in international markets. With the EV market continuing to grow, BYD is well-positioned to capitalize on this trend and further expand its sales. CnEVPost

CATL has launched a battery lookup tool to help Chinese EV buyers verify the authenticity of their vehicle's battery. This tool is designed to reinforce the company's premium positioning and provide customers with an added layer of assurance. The battery lookup tool allows buyers to check the authenticity of their battery by entering the battery's serial number or other identifying information. This move is seen as a way for CATL to differentiate itself from other battery manufacturers and provide a higher level of quality and service to its customers. By launching this tool, CATL is demonstrating its commitment to customer satisfaction and its focus on providing high-quality products. CnEVPost
