ELI5: Why do you not get shocked if car chassis is used as
So by striking the jumper cables here you would max out the 12v car battery at about 25 amperes and the 9v battery at about 0.5 amps. But with the tongue as a resistor (20,000 ohms) you wouldnt get more than 0.001 amps. Above 0.1 amps is where you can die. I did the math so you all dont have to lick a car battery.

6 FAQs about [Why are new energy batteries all in the chassis]
How are structural batteries changing the way electric cars are assembled?
Structural batteries are changing the way electric cars are assembled. Structural adhesives are replacing screws and welds to “glue” components together using a process called adhesive bonding. This process requires additional surface preparation and creates new challenges for automakers and battery makers.
Why do electric cars use structural batteries?
As a result, redundant structural elements can be removed, eliminating weight from other parts of the vehicle. They are said to offer “massless energy storage” because their effective weight is lower than the total weight of the cells (considering the parts they replace). Structural batteries are changing the way electric cars are assembled.
Why should a battery pack be integrated with a vehicle body?
Integrating the battery pack with the vehicle body in design and manufacturing also reduces the number of components, increases production efficiency, lowers costs, and enhances vehicle performance.
Can structural battery composites improve EV performance?
Carlstedt and Asp developed a performance analysis framework to study the benefits of using structural battery composites in EVs . Their case study manifested that the driving range could be increased by 70% for lightweight vehicles with feasible structural battery designs.
Why do cars use battery cells?
This reduces the weight of the vehicle and frees up space that would have been needed for a large battery pack. The cells are cheaper to manufacture than the alternative design of cell modules that are connected into packs.
Why are lithium-ion batteries used in electric vehicles?
