all about hybrid car batteries

In addition to gasoline engines, hybrid cars are also driven by electric motors that rely on batteries.
The hybrid car battery is produced in a similar way to the traditional car battery and has similar functions.
The only difference is that the battery of a hybrid car is larger in size and is able to produce a large amount of power required.
But compared to the batteries of pure electric vehicles, the batteries of hybrid cars are smaller, because hybrid cars also use gasoline engines.
In order to meet the needs of hybrid vehicles, their batteries have internal structures and materials that are different from traditional batteries.
The battery of a hybrid car may contain several modules, each of which contains a row of batteries.
At 2009 Toyota Prius, 201. 6-
There are 28 modules in the V battery pack.
Each module is usually packed in stainless steel and contains 6 batteries, so there are 168 batteries in the whole package.
The battery voltage of 650-is reversed to AC
AC motor.
When the package fails, it is likely that the module is defective and can be rebuilt by replacing the appropriate module.
In any car, the rechargeable battery is the starting motor, lamp, engine ignition system and accessories and 12-V lead-
The acid battery can provide the required power.
In a hybrid car, another rechargeable battery is used to drive the motor of the wheel, which means more powerful high
Voltage battery is required. Lead-
The acid battery is heavy and cannot provide the required power in a small package.
Therefore, for practical purposes, most automakers have turned to other types of rechargeable batteries. Today, nickel-metal hydride (NiMH)
Most hybrid cars have batteries installed.
Over 2 million worldwide.
The electrode used in the NiMH battery is hydrogen-
Absorption alloy of negative nickel hydroxide and positive electricity.
Toyota Prius, Honda Civic Hybrid and Honda Insight use NiMH batteries, among others.
Another type of battery is a lithium ion battery with more power in a smaller package.
Lithium-ion batteries are composed of anode, cathode and electrolyte.
The anode is carbon like graphite.
The cathode is a layered oxide of lithium cobalt oxide, or lithium ion like lithium iron phosphate or lithium manganese oxide.
Electrolyte is a non-
Water Organic carbonates containing lithium ion complexes.
The Honda hybrid will start using lithium batteries.
Although Toyota has gained benefits in extracting lithium, it insists on using NiMH (
It takes about $4,000 to replace)
Instead of lithium at a higher cost.
But it is predicted that lithium may be the key to making hybrid cars more affordable in the future.
Hybrid cars can reduce fuel consumption, thus reducing pollution.
Discarded batteries have toxic effects on the environment, which will only change one problem to another.
All types of batteries have their environmental risks.
As far as the battery is mainly composed of materials, lead is the most harmful and lithium is the least harmful.
Nickel is in the middle.
But if cobalt is used in lithium batteries, that would be a problem.
Recycling Technology plays an important role in the environmental impact of these materials.
Lead has proven recycling technology, but thousands of metric tons of lead are buried each year.
Full recovery of Nickel remains a challenge and nickel is considered a possible carcinogenic substance.
Currently, only a few million of the world\'s 0. 7 billion vehicles are a fraction of them.
However, with the increase in the production and use of hybrid cars, their battery impact on the environment will have corresponding problems and must be solved as soon as possible.
