Deep Discharge Batteries Ohmmu LiFePO4 : Electric and Hybrid Cars, Campers, Powerboats
Are you tired of short battery life or poor performance in sub-zero temperatures?
Maybe you are looking for an alternative solution to acid batteries?
In this case, take a look at LiFePO4 Ohmmu batteries.
What is the Ohmmu LiFePO4 deep discharge battery?
“Ohmmu Energy” is a US company specialising in the design and manufacture of advanced lithium-ion batteries.
Ohmmu batteries are unique in that they are based on a new type of technology called lithium iron phosphate (LiFePO4) chemistry and are different from conventional lithium ion batteries.
This technology has several advantages over traditional lithium-ion batteries:
-
is much safer and more stable than other chemicals, which means it is less likely to overheat or catch fire.
-
it has a longer lifespan than other lithium-ion batteries, meaning it can be used for a longer period of time before needing replacement.
Finally, they are more environmentally friendly than other lithium-ion batteries because they contain less toxic substances.
"Ohmmu Energy" also adhere to sustainability and ethical business practices, buying materials from trusted suppliers and ensuring that their batteries are responsibly manufactured.
"Ohmmu batteries are recycled at the end of their useful life.
Main applications of the LiFePO4 Ohmmu deep discharge battery
1. For electric vehicles
Ohmmu batteries can be used in electric vehicles, which are a clean and efficient alternative to traditional petrol-powered vehicles.
2. For Electricity Storage
Ohmmu batteries can be used to store energy generated from renewable sources such as solar or wind power.
3. Used as Backup Power Sources at Home
Ohmmu batteries can be used as back-up power supplies in the home. In the event of a power outage or other emergency, a battery can provide a reliable source of power to keep your home's most important systems running.
What Are Advantages of the LiFePO4 Ohmmu Deep Discharge Battery
More Efficient
OHMU means better performance of the 12V battery.
The graph shows the average life cycle of an Ohmmu battery compared to an acid battery.
More cycles = longer battery life
Less Toxic
Lead-acid batteries are one of the most toxic products on the planet and their recycling/production has become a serious global problem.
Ohmmu lithium 12V batteries are not only cleaner, but they use 70% less resources to produce and last 4 times longer, so only 1/4 of the batteries need to be produced in the first place.
More Efficient
Less energy loss = higher efficiency.
Up to 60% less weight than original Tesla batteries.
How are Ohmmu batteries tested?
"Ohmmu Energy" has invested significant time and resources in building a state-of-the-art research and development laboratory where the most extensive testing of battery cells and battery assemblies takes place.
No other supplier of these battery solutions performs this level of OEM Tier-1 testing!
Thermal chambers simulate extreme heat and extreme cold conditions.
The thermotron chamber allows you to push the boundaries by reaching temperatures as low as -70 °C (-94 °C) and as high as 185 °C (365 °C) at high temperatures.
All products sold are tested (according to IEC 60068-2-1), so the company guarantees 100% of its batteries.
The vibration simulators perform standardised tests on batteries in accordance with IEC 60068-2-64, which is an OEM automotive-grade standard used to ensure the longevity and durability of components.
In these tests, the components are tested for up to 60 hours at 10-1000 Hz.
Vibration tests are carried out after temperature stress testing of the batteries to ensure their safe use in vehicles for the lifetime of the battery.
Charge, discharge and cycle test machines allow you to simulate variable loads that reflect the operating conditions of the battery.
“Ohmmu Energy” uses equipment that allows continuous testing of 12V batteries with charging and discharging currents exceeding 100 A.
To simulate duty cycles and to assess the rate of degradation, continuous cycle tests are carried out in which the batteries are cycled from 0 % to 100 % and from 0 % to 0 % without end.
Various load and cycle test protocols are carried out through extreme cold, extreme heat and vibration simulations to ensure performance under realistic conditions.
FAQ
How do LiFePO4 batteries perform at low temperatures?
As with all batteries, cold temperatures reduce their performance. LiFePO4 batteries have a significantly higher capacity and voltage at cold temperatures compared to lead acid batteries.
Important tips to keep in mind: when charging lithium iron phosphate batteries at temperatures below 0 °C, the charging current should be reduced to 0.1C and to 0.05C below -10 °C.
Failure to reduce the current below zero may result in irreversible damage to the battery. The OHMMU series batteries are specially designed for cold charging, using the charging current to warm the battery before allowing it to charge.
How are LiFePO4 Ohmmu batteries safer than other lithium batteries?
Phosphate-based batteries have a better chemical and mechanical structure that does not overheat to unsafe levels.
This provides increased safety compared to lithium-ion batteries made with other cathode materials.
This is because the charged and uncharged states of LiFePO4 are physically similar and very robust, allowing the ions to remain stable during the oxygen flow that accompanies charging cycles or potential failures.
In general, the iron phosphate-oxide bond is stronger than the cobalt-oxide bond, so when the battery is overcharged or physically damaged, the phosphate-oxide bond remains structurally stable, while in other lithium chemicals the bonds begin to break down and release excessive heat, which eventually leads to a thermal "leak".
Lithium phosphate cells are non-flammable. They can also withstand harsh conditions, be it cold or heat. In the event of a hazardous event, such as a collision or short circuit, they will not explode or ignite, greatly reducing the likelihood of any damage.
If you are choosing a lithium battery and intend to use it in hazardous or unstable environments, LiFePO4 is the best choice.
LiFePO4 batteries are non-toxic, non-polluting and contain no rare earth metals, making them environmentally friendly.
