Lead-Acid Battery Temperature Sensor

Lead-Acid Battery Temperature Sensor

A lead-acid battery temperature sensor monitors ambient temperature of a lead-acid battery in real time to provide charge temperature compensation.

NOTE:
Due to the negative temperature feature of a lead-acid battery, the charge voltage must be adjusted based on the ambient temperature. The battery charger must provide higher charge voltage when the temperature is low and provide lower charge voltage when the temperature is high, so that the lead-acid battery can be fully charged. The PBB-12AHA module can control the charge voltage for the lead-acid battery based on the temperature collected by the temperature sensor. Using a temperature sensor can prolong the life time of the lead-acid battery.

Appearance and Structure

Figure 9-44 shows the appearance of a lead-acid battery temperature sensor.

Connection

Follow these instructions when using a lead-acid battery temperature sensor:

  • Connect the cable connector to the SENSOR port on the PBB-12AHA lead-acid battery charger module.
  • Place the temperature probe (with an OT terminal) where it can collect the most accurate ambient temperature of the lead-acid battery. You are advised to place the temperature probe near the lead-acid battery and bind the sensor cable with the power cables of the lead-acid battery. Do not connect the temperature probe to any other heating device. Hang the temperature probe in air and keep it away from any heating device.
