Description

Technical Field

[0002] The Blade Battery uses lithium iron phosphate technology and is a battery product released by BYD on March 29, 2020. Through structural innovation, the Blade Battery can skip modules when grouping, greatly improving the volume utilization rate and ultimately achieving the design goal of fitting more battery cells in the same space.

[0003] The working principle of the blade battery is that when the external circuit is connected to the circuit board, the blade extracts charge from the semiconductor surface, and this charge will continue to accumulate between the two plates. The accumulated amount of electricity is equal to the charge extracted by the blade, and the charge existing outside the entire circuit board is equal to the extracted charge. In the circuit board, the speed of charge accumulation is equal to the speed of charge extraction, so the accumulation of charge will not affect the working voltage and current of the circuit board, and when the circuit board is turned on, the stored charge will be output to the outside.

[0004] During the battery pressing process, the batteries and pressing plates need to be placed one by one. During the installation of blade batteries and pressing plates, there are uneven pressing forces and skewed pressing, which causes damage to the product and increases production costs.
