Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] An overcurrent control method based on the Wsa charging curve of the present invention, which calculates the theoretical current value on the Wsa charging curve by monitoring the battery voltage and the grid voltage value during the whole charging process, and automatically sets the value at different positions of the Wsa curve Different charging current over-current protection value.

[0024] see image 3 , at any position of the Wsa charging curve, the theoretical charging current value under the battery voltage and grid voltage value is distributed within a certain range, if the actual measured charging current exceeds 1.3 times the upper limit A or lower limit B of the theoretical charging current value, Then the charger judges that the charging is over-current and stops charging.

[0025] The calculation formula of the theoretical...

Abstract

According to the overcurrent control method based on a Wsa charging curve, the voltage value of the storage battery and the voltage value of the power grid are monitored in the whole charging process,the theoretical current value on the Wsa charging curve is calculated, and different charging current overcurrent protection values are automatically set at different positions of the Wsa curve. At any position of the Wsa charging curve, the theoretical charging current numerical values under the storage battery voltage value and the power grid voltage value are distributed within a certain range, and if the actually measured charging current exceeds 1.3 times of the upper limit or the lower limit of the theoretical charging current numerical value, the charger judges that charging is over-current and charging is stopped. A lead-acid storage battery can be protected.

Description

technical field [0001] The invention relates to the technical field of charging lead-acid batteries, in particular to an overcurrent control method based on a Wsa charging curve. Background technique [0002] see figure 1 and figure 2 , it can be seen from the Wsa charging curve that the charging current decreases with the increase of the battery voltage. In addition, the charging current also increases with the increase of the input grid voltage, and decreases with the decrease of the grid voltage; the current during the charging process is not a fixed value, so, It is impossible to use fixed upper and lower limits as the current protection value. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an overcurrent control method based on the Wsa charging curve for the problem that the existing lead-acid battery cannot use the fixed upper and lower limits of the charging process current as the current protection va...
