One microprocessor 20, in have a detecting pattern decision-making process;
One load unit 21 ' is electrically connected to this microprocessor 20, supplies cross-over connection between the positive and negative electrode 31 of storage battery 30 to be measured;
One state of charge detecting unit 22 is electrically connected to this microprocessor 20, supplies to be connected between the positive and negative electrode 31 of this storage battery 30 to be measured, and detecting magnitude of voltage and the current value of storage battery 30 to be measured between detection period, and this microprocessor 20 is given in repayment.
Said detecting pattern decision-making process is as shown in Figure 3, includes:
Read the storage battery capacity (CCA to be measured that input media is obtained
B) and voltage (V
B) (S30);
Read the output current value (I that loads back storage battery 30 to be measured
B) (S31);
Be the basis with detected output current value, cooperate preset testing conditions (1/2 CCA, 15 second load time) the adjustment load time wherein:
and
Carry out trace routine, to obtain a detection curve figure (S33).
Illustrate, desire adopts the storage battery 30 of a 12V/1000 CCA capacity of fixed test condition (1/2 CCA, 15 second load time) detection, and load unit 21 ' comprises one 0.12 ohmic resistors.This microprocessor 20 loaded before carrying out trace routine in advance, and 0.12 ohmic resistor is connected to two leads 12 to be measured, to detect the output current value (I of storage battery 30
B), making it is 100A.Because 30 its load times of storage battery that capacity is different are also different, so bring the load time calculating formula into: [(1000*1/2)/100] * 15=75, the load time in the adjustment testing conditions is 75 seconds.
In present embodiment, detect the storage battery 30 of a 12V/900 CCA capacity equally with employing fixed test condition (1/3CCA, 20 second load time), and load unit 21 ' comprises one 0.08 ohmic resistors.This microprocessor 20 loaded before carrying out trace routine in advance, and 0.08 ohmic resistor is connected to two leads 12 to be measured, and to detect the output current value of storage battery 30, making it is 150A.Because 30 its load times of storage battery that capacity is different are also different, so bring the load time calculating formula into: [(900*1/3)/150] * 20=40, the load time in the adjustment testing conditions is 40 seconds.
