BATTERY THERMAL RUNAWAY SYSTEM OPTION SECTION
SECTION 1
System Description
The Thermal Runaway Detection Option consists of two components. The first
PCB component is the Power Supply Relay PCB that performs a summary dry
contact closure on an alarm from any of the temperature sensor boards. This
PCB is shown in Picture 1. The second PCB component is a Temperature
Sensor PCB that measures the temperature from each battery, runs an
algorithm, and sets an alarm if there is a troubling condition. The temperature
sensor PCB is shown in Picture 2.
Power Supply/Summary Relay PCB connections
The Power Supply and Summary Alarm PCB can be identified by the assembly
number PCB404394XXX. The main power is supplied to the connector on the
left. If jumpers R4 and R5 are installed the input voltage required is 115vac. If
jumper R3 is installed then the input voltage is set up to accept a 230vac input.
Connector J2, in the center on the right side of the PCB is used to supply the
power to the Temperature Sensor PCB as well as collects the alarm trigger from
the Temperature Sensor PCB. The connectors on the right at the top and bottom
as shown provides the summary dry contacts for the alarm signal.
