Problems solved by technology

[0004] The traditional charging pile uses a uniform current to charge the battery, which often causes warping and deformation of the battery plate, increased acid concentration, and battery expansion due to excessive charging current, thereby accelerating the aging of the battery. Shorten the service life of the battery and cause irreversible damage to the battery

Abstract

The invention provides an accumulator charging method, a device and a charging pile, and relates to the technical field of the accumulator charging. The method comprise the following steps: acquiring a voltage value of a to-be-charged accumulator, wherein the first voltage value is the voltage current of the to-be-charged accumulator at the current moment; determining an initial specification attribute of the to-be-charged accumulator according to the first voltage value, wherein the initial specification attribute comprises a first charging voltage which is the charging voltage for performing constant voltage charging on the to-be-charged accumulator; performing at least one staged charging on the to-be-charged accumulator by using the second charging voltage so that the difference between the voltage of the to-be-charged accumulator and the first charging voltage is less than a preset difference, and the second charging voltage is less than the first charging voltage; and performing the constant voltage charging on the to-be-charged accumulator through the first charging voltage after performing the staged charging on the to-be-charged accumulator. The technical problem that the accumulator is easy to damage by using the traditional charging pile to charge the accumulator is relieved.

Description

technical field [0001] The invention relates to the technical field of battery charging, in particular to a battery charging method, device and charging pile. Background technique [0002] With the development and popularization of new energy technologies, electric vehicles gradually replace traditional fuel-driven vehicles, and electric vehicles often need to charge batteries of electric vehicles during daily use. [0003] When the electric vehicle is parked at home or in the company, it is convenient to use the adapter charger that comes with the electric vehicle to connect to the mains to charge the storage battery. However, the vehicle is often driven outside. If the battery needs to be charged, the battery is usually charged through the charging pile of the fast charging station. [0004] The traditional charging pile uses a uniform current to charge the battery, which often causes warping and deformation of the battery plate, increased acid concentration, and battery ...
