Design scheme of 115.2v rail transit bridge inspection vehicle

With the development of rail transit industry, lithium batteries are gradually replacing lead-acid batteries. Lithium batteries are the main power source. They have many advantages that lead-acid batteries do not have, such as environmental protection, convenience, safety, light weight and small volume. High voltage lithium batteries are used in bridges, ships, yachts and other large projects.
