We tend not to do it nowadays because negative grounding reduces galvanic corrosion of the frame of vehicles. You can call anything in a circuit "ground". "Ground" is just a reference point. Ground can be anywhere in the circuit, but it is usually near the power supply, because current going into or coming out of ground needs to go somewhere.
Wiring the negative poles together is correct. Remember that in the car the chasis is used for negative potential. The Ground connection of your Inverter should be grounded correctly.
Well there are some uses of a positive ground but that's rare outside of telephone gear. Generally the negative post on the battery is grounded to the chassis of a vehicle. The reason for this was touched on in other answers, the need for two fuses is to cover some known failure modes.
As the power supply has no ground / earth / chassis connection there is no danger of a single fault causing an alternate return path. Figure 1c is the way most vehicles are wired with a negative connection to the chassis. The fuses are placed in the positive lines from the battery and close to the battery.
Electrical Engineering Stack Exchange grounding, whats its purpose? Some say Ground is just a reference point for measuring voltages, some say ground is a safety device for appliances and some say ground is just a bare piece of metal regardless if its even connected to the actual earth (as in dirt)
It is just that the lack of electrons on one end attracts all the electrons crowded in the metal conductors like they were cars on a highway at rush hour. Negative is usually connected as ground because a large metal object usually has an excess of electrons which - if pulled away - won't cause an imbalance of voltage in it.
Check The Earthing Pints For Lithium-ion Batteries: ... Which cable indicates the ground of a battery? The negative cable indicates the ground connection of the battery and is mostly connected to the chassis of the vehicle …
Now they have excluded the GND cable at the negative pole of the DC distributor. So the system is not grounded at the negative pole anymore. Why did they change it? Is it …
Remember that in the car the chasis is used for negative potential. The Ground connection of your Inverter should be grounded correctly. So you can wire it to a metal pole, …
Question 1: In the BYD example diagram (shown), in wiring unlimited and several other sources, it is mentioned that the negative battery pole should be grounded. In this case the BYD battery …
If we know that in reality electrons flow from negative to positive, then why is the negative terminal of a battery usually still connected as the ground, and things such as switches usually connect …
Since the negative terminal of the battery is normally considered "Ground" or "Zero Volts", a fuse in the negative lead would leave the rest of the circuit "hot" - usually Not a Good Thing. Recommended practice is to place …
Which cable indicates the ground of a battery? The negative cable indicates the ground connection of the battery and is mostly connected to the chassis of the vehicle which …
Assemble a few examples like the circuit you were given, and measure the voltages using different "ground points." Use the minus pole of the battery, then the plus pole …
Download figure: Standard image High-resolution image Pole-piece position distance defects are mainly produced in the winding or stacking process of a battery. Also, …
A short-cut of a lead-acid (or even worse: lithium) battery is very dangerous! To avoid this situation you connect both "plus" poles first and when connecting the second end of the …
One reason is if you develop an AC to DC fault in for example an inverter. If the DC is floating then the AC to DC fault will raise the DC to a dangerous voltage. Grounding the …
Remember that in the car the chasis is used for negative potential. The Ground connection of your Inverter should be grounded correctly. So you can wire it to a metal pole, take a hammer and push it into the earth or …
This is a common way to integrate a battery protection IC. The protection IC controls the two mosfets in Q1. If the battery is overdischarged, it turns off the right mosfet, …

The EasySolar ground is connected to the lightning rod in order to be grounded. I worry a little bit, that a lightning impact might damage the electronics, due to the high resistance in to the …
Since the negative terminal of the battery is normally considered "Ground" or "Zero Volts", a fuse in the negative lead would leave the rest of the circuit "hot" - usually Not a …
When you ground the battery bank (negative battery bus ground bonding to ground rod/cold water pipe/etc.) it makes sure that the negative terminal can never get above zero volts. So shorting …
Secondly, you do NOT hook a battery charger up to charge a battery by applying an alternate ground source, i.e. an engine block. The ground connection for a battery …
If V 1 is greater than or equal to V 2, insert a standard known resistance (R 0) between the negative pole of the tested-device and the ground connection. With Ro installed, …
If we know that in reality electrons flow from negative to positive, then why is the negative terminal of a battery usually still connected as the ground, and things such as switches usually connect …
Which cable indicates the ground of a battery? The negative cable indicates the ground connection of the battery and is mostly connected to the chassis of the vehicle which can be removed easily without the creation of …

Another reason you''re supposed to use a chassis ground to jump start instead of the battery''s negative pole is to stay away from the battery sensor (Part Number: 38920-TZ5 …
Negative pole interruption is a vital safety feature in lithium-ion battery systems. By preventing overcharge, over discharge, and other hazards, it helps ensure the...
If your vehicle has a BMS you cannot connect to the negative battery pole, the connection must be made to the earth or ground point, if you are in any doubt then connect to the nearest earth …
