How To Count Battery Block Volume Prius

Thinking about your vehicles battery? Wondering if you are working at the right speed? We could help. Learn what the best tools are to make these tasks easier.

What is a Battery Block?

At this point, it is important that you understand what a “battery block,” or battery, is and how they are related to the size of the Toyota Prius. Many batteries are stamped out of metal at a factory where they take shape. Some batteries, such as those in Tesla cars, are made instead through an additive manufacturing process (3D printing) that builds up layer after layer to achieve any size desired.

The battery block is the part of your Prius that contains the battery. The dimensions/size of your battery block is normally 40” x 12” x 28”.

The original battery for a Toyota Prius is about the size of a 4-filter coffee pot. With today’s hybrids cars, it’s possible to have over 100 horsepower with modern batteries from groups 3, 4, and 5.

How to count battery block volume

Prius batteries can be found under the passenger side of the car where you will find eight 9-volt batteries. You need to know how many blocks your battery has for safety purposes because if you make a jump pack, you will know how many blocks it needs and what size jump batteries to order.

A battery block is the home of your Prius’s batteries. Most years, there are 8 battery blocks in each Prius. Each battery block is filled with 10 total cells. The cells of a Prius worth 2.5V each and the batteries worth 13.3V Every battery block has an average rating of 4,500mAh so that’s approximately 23-watt hours in power located per cell, a total of 728Wh.

To determine how many battery cells are in an electric car, it is easiest to take the length of the cells parallel to each other. The length will be divided by 4 for a rough estimate. For example, if a battery is 34 inches long, then it contains 4 cells.

Tips to save money on your car’s battery

Learning how many battery volts you actually have in your car is important when saving money on your car’s replacement. There are many ways to do this, but one of most simple is with a voltmeter. Bring this into a shop and ask them what the number is for their system.

One of the most expensive parts on a vehicle is the battery. If possible, it is important to count the total volume of all the cells and know how many you have left before sending your car in for replacement. Doing so will save you a significant amount of money when purchasing a new battery as it can cost $1 to $4000 or more depending on size.

I didn’t count all the block space in the Prius battery yet, but I was able to estimate how much it has. My calculations end up with 79.6 cubic feet of block volume plus three-tenths of a battery unit equals 120.26 cu ft of total space in the battery.

Counting the battery block volume of a Prius is a simple way to identify how much it will cost to replace the battery. To do this, you simply take the ratio of 24 volt – 12 volt to find out how many amps would run through one coil. This calculation can be completed by multiplying the number of blocks, v, by rho, where rho is equal to pi squared divided by four.
The calculation for each potential size can be done easily for each system in order to determine which make and model of car to install a new battery system into.
