Problems solved by technology

[0005] Fast charging, also known as emergency charging, refers to a mode of charging electric vehicles with a large current within a short period of 30 minutes to 2 hours. The charging time is short, and the general charging current is 150-400A. Due to the large charging current, It is easy to cause battery abnormality, resulting in short battery life and potential safety hazards, and high current may also have a harmful impact on the public power grid

Embodiment 1

[0044] Embodiment 1, high-frequency pulse fast charging method, the charging method provides:

[0045] A multivibrator step, generating continuous t1 pulse signals and t2 pulse signals;

[0046] A charging switch step, when the multivibrator step generates a t1 pulse signal, the storage battery is positively charged within the t1 pulse period;

[0047] A monostable step, when the multivibrator step generates a t2 pulse signal, a pulse control signal with adjustable width is generated;

[0048] A discharge switching step, when the monostable step generates a trigger pulse, the storage battery is discharged within the trigger pulse period;

[0049] When the monostable step stops generating trigger pulses, the storage battery will suspend discharging during the stop period;

[0050] Before the multivibrator step generates the t1 pulse signal again, the charging switching step and the discharging switching step stop.

[0051] During the t1 pulse period, the multivibrator step g...

Abstract

The invention discloses a high-frequency pulse fast charging method. In the multi-harmonic oscillation step, a continuous pulse signal t1 and a continuous pulse signal t2 are produced; when the pulse signal t1 is produced in the multi-harmonic oscillation step, a storage battery is charged in the forward direction within the pulse t1 period; when the pulse signal t2 is produced in the multi-harmonic oscillation step, a width-adjustable pulse control signal is produced; when a trigger pulse is produced in the mono-stability step, the storage battery is discharged within the trigger pulse period; when production of the trigger pulse is stopped in the mono-stability step, discharging of the storage battery is suspended within the stopping period; before the pulse signal t1 is reproduced in the multi-harmonic oscillation step, the charging switching step and the discharging switching step are stopped, wherein charging time is 2-3 hours, and the service life of the storage battery is prolonged by 1.5-2 times.
