Battery Cell Thermal Control in Electric Vehicles Using Water Cooling Block

Research and development efforts in the field of transportation have recently focused on creating clean, safe, and high-efficiency modes of transportation. It has repeatedly been predicted that electric, hybrid, and fuel-cell vehicles will soon displace conventional automobiles. This research offers an illustration of how a battery-electric vehicle may regulate the flow of coolant over specific battery cells. Each lithium-ion battery cell's heat level is measured by a sensor, which also controls the cooling process. The PID controller (Arduino) and Water Pump both function using a 12V rechargeable battery. Temperature sensors are employed to monitor each Li-ion battery cell independently and provide feedback as an analog signal. The flow of the pump is controlled by the battery's feedback, and the coolant goes via a convey to achieve temperature control. When compared to lead-acid / nickel-metal hydride batteries, lithium-ion batteries offer better energy densities. Moreover, it is far less expensive and doesn't need nickel or cobalt. Also, it is safer since it is more stable. Each battery cell has a water cooling block installed specifically for more effective cooling. When compared to the method of calculating the total battery heat without any controller on any individual cells of the battery, the method of implementing a water cooling block in individual cells will be more effective. The temperature variation in the battery cell was significantly decreased by a water cooling block, which also lowered the thermal effect by around 40%. In the battery cell, a number of cycles and the depth of discharge are recorded, and the findings show that while the coolant temperature rises from roughly 30°C to 50°C, the battery cell's interior temperature drops drastically from 60°C to 20°C of heat.
