Description
Technical field
The present invention relates to lead accumulator field, be specifically related to a kind of valve-regulated lead-acid battery group life detecting method and pick-up unit.
Background technology
Current battery life detects uses following methods to complete: lie on test platen after battery pack being charged completely, then adopts to be connected in series mode and to receive on charging set, and transfixion is 25 DEG C in temperature
dEG C environment in leave standstill 10 minutes, according to certain charge-discharge procedures, carry out life tests test.Can not travel on very smooth road owing to riding Moped Scooter always, can constantly vibrate in the process travelled, the state such as have upward slope, slide, do not move at all unlike in the lab, therefore the cycle life in laboratory tests not closing to reality, though there is certain reference value, but the life-span that electric battery is real can not be detected exactly.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of valve-regulated lead-acid battery group life detecting method and pick-up unit, changes static lower battery pack cycle life detection experiment the data obtained in the past and really can not reflect actual service life state.
The present invention is achieved through the following technical solutions:
A kind of valve-regulated lead-acid battery group life detecting method, comprises the following steps:
After the battery pack be placed on vibration test making machine vibration table is connected in series, be connected with charge-discharge machine, open charge-discharge machine and run charging procedure: first charge to 57.6V with current limliting 2A or charge 6 hours, then with current limliting 1.5A, constant voltage 59.2V, charging and complete charging in 3 hours;
Charging terminates rear unlatching vibration test machine, and adjusting its frequency is 18HZ, amplitude 3mm, run discharge procedures: first with 15 ~ 20A constant-current discharge, 5 ~ 10S, then with 7 ~ 9A constant-current discharge 5 minutes, last 6A is discharged to final voltage 42V and completes electric discharge, closes vibration test machine;
Then run charging procedure charging after electric discharge terminates, the above-mentioned charge-discharge procedures of repetitive cycling, until discharge capacity is 70% of rated capacity, stop detecting, finally statistics electric discharge total degree, can draw battery life number of times.
A kind of valve-regulated lead-acid battery group life detecting device, comprise charge-discharge machine and vibration test machine, the battery pack be connected in series is placed on vibration test machine, is connected with charge-discharge machine.
Further improvement of the present invention scheme is, the frequency of described vibration test machine is 18HZ, amplitude 3mm.
The present invention compared with prior art, has following obvious advantage:
The discharge procedures of the present invention by using special simulating electric car to travel duty, in conjunction with a vibration test machine.Vibration test machine has imitated the frequency in electric motor car travel operation state, is organically coordinated by them, and life tests test really can reflect the service life state of battery pack reality.
