Project 1

Design a battery pack for a car roughly 150 Kw with 120 V. Use 3500 mAh 3.6V nominal NMC chemistry cell.

1. Design the battery pack configuration.

2. Draw the BMS topology for this battery pack.

We Have Design a battery pack for a car roughly 150 Kw with 120 V. Use 3500 mAh 3.6V nominal NMC chemistry cell.

Calculations

Given Data:-

Nominal voltage = 3.6v

Capacity = 3500mAh = 3.5Ah

2. Draw the BMS topology for this battery pack.

There Are Four Types Of topology As following :-

1. Centralize Topology.

This Type Of topology Used in Less then 18 Cell So This are Reject.

2. Master and sleeve Topology.

This Type Of topology is used in Four Wheelers and Large energy system so we choose this Topology for our System.

3. Moduler Topology.

This Type of Topology used in more then 1 MW Battery Pack system so This is also rejected

4. Distributed Topology.

This Type of topology used in Very small amount battery pack this is also Rejected.

In the Master and sleeve Topology we Divided in Four Group Of sleeves.

First To Three Sleeve Contains 18 Cells And Four Sleev Contains 14 Cells .

So we will choose the master and sleeve Topology

Number Of cells in series is the main Factor For choosing the Topology.

We Designed The Battery Pack For 150 Kw with 120 V.
