Abstract

The invention discloses a lithium battery charging control method, device and system and a battery management system. The lithium battery charging control method comprises the following steps of detecting parameters of a lithium battery; calculating charging currents of the lithium battery; controlling a battery charger to charge the lithium battery according to the charging currents. The lithium battery charging control method solves the problem that, in the prior art, the service life of the lithium battery is shortened due to the fact that the lithium battery is easy to be over charged and achieves the effect that the service life of the lithium battery is improved.

Description

technical field [0001] The present invention relates to the field of lithium batteries, in particular to a lithium battery charging control method, device and system, and a battery management system. Background technique [0002] Lithium-ion batteries have the advantages of high single operating voltage, small size, light weight, high energy density, long cycle life, small self-discharge current, no memory effect, no pollution and high cost performance. In recent years, the output of lithium-ion batteries has been rapid With the development and continuous expansion of application fields, it has become a high-tech product of great significance in the 21st century. The discharge curve of lithium-ion batteries is very flat and can generate stable power during the entire discharge period of the battery. Therefore, lithium-ion batteries have become the first choice for automotive power batteries. But at the same time, the shortcomings of lithium-ion batteries are also very obvio...
