Lithium battery protection device for battery to carry on the design of an intelligent system, because each user's car is unknown, avoid all kinds of problems in the later stages of the use, we need to know the various technical parameters of the battery and the existing state of each, do not match the weight on the fork, the output current is different, the consumption of time every day and not balanced, the proportion of the charging time vehicle circuit result in electrolyte of lithium battery forklift volatile too fast, and so on, can according to the following conditions to develop new protection device battery undervoltage: when the battery reaches under-voltage point buzzer slow, once every 5 s chirping, the user to confirm to cancel the alarm, abnormal voltage indicator panel.
Undervoltage condition: when the battery voltage is less than the total of under-voltage alarm when setting under voltage value.
Battery over-voltage: when the battery reaches over voltage point buzzer slow, once every 5 s chirping, the user to confirm to cancel the alarm, abnormal voltage indicator panel.
Overvoltage conditions: when the battery voltage is greater than the always set overvoltage value for over-voltage alarm.
Single section exception: when abnormal cells single section (
Differential pressure is too big)
Every 2 s, buzzer alarm, the user to confirm to cancel the alarm, panel lights.
Abnormal condition: when a single day compared with single section average voltage, voltage differential value is greater than setting the differential value of monomer faults.
Temperature anomaly: when found the battery temperature too high or too low, buzzer once every 5 s alarm, the user to confirm the information to cancel the alarm panel temperature anomaly indicator.
Abnormal condition: when there is a certain section temperature detection more than 40 degrees or below 15 degrees temperature abnormal alarm, when all the battery detection unit temperature below 37 degrees or above 18 degrees return to normal.
