Why is BYD lithium battery module 14 string or 18 string?
BYD's lithium battery module is 14 string or 18 string, because it provides higher voltage and energy density and limits the size of the battery pack. The lithium battery modules used in BYD cars are configured as 14 or 18 strings to meet the high voltage requirements of electric vehicles and the energy density requirements of battery packs. Higher voltage can improve power efficiency and cruising range, while reducing current transmission loss. BYD's lithium battery modules are 14 or 18 strings, because they provide higher voltage and energy density and limit the size of the battery pack. BYD is a well-known comprehensive new energy automobile manufacturer in China, headquartered in Shenzhen, Guangdong Province. BYD not only produces electric vehicles, but also involves batteries, photovoltaic power generation, lighting equipment and other fields.
