Society is increasingly leaving fossil sources behind, and making the leap to more efficient and ecological solutions. One of the protagonists in this transition is the lithium battery. With its increasing popularity, some erroneous beliefs have also spread. There are those who claim that they are highly flammable, when in reality the safety of lithium batteries is very high. Today we explain the keys and essential role of the manufacturer NCPOWER in this regard.
In terms of the flammability of a lithium battery, the lithium battery manufacturer plays a key role and can do a lot during the design, material selection and manufacturing phases to ensure that the batteries are safer and therefore minimize risks.
5 Factors to achieve safety in lithium batteries
When evaluating whether a lithium battery is safe or whether another type is better, we must take into account some key criteria. Below we indicate the different points that allow us to detect if it is a safe battery and to what degree.
Choosing the appropriate chemical structure
There are a wide variety of chemistries to choose from when looking for advanced lithium batteries.
At NCPOWER we work with the LiFePO4 (lithium iron phosphate) chemistry for the electrification of electric vehicles, since it is the safest and most stable chemistry currently available on the market.
In addition, the LifePo4 lithium batteries guarantee more than 4,000 life cycles. For this reason, we call them “the most durable and safest batteries on the Spanish market.”
Cell assembly for battery safety
On the other hand, another factor of special relevance in the safety of lithium batteries is the assembly of the cells. Lithium batteries are made up of small cells placed in parallel. If the number of cells assembled is less, then we can consider the battery to be safer. Since there are fewer variables, the risk of short circuit is reduced. The fewer parallel cells assembled in a battery, the greater the safety.
In the case of NCPOWER, our batteries are customized according to the needs of each client. Among these needs is the power of the electric vehicle and after a rigorous study, we adapt the battery, optimizing its performance and minimizing the number of cells to improve its safety.
Battery control and electronicsAnother key factor to be able to anticipate and avoid any risk is to have a control system. The BMS of our batteries is a management software that communicates directly with a device built into the batteries. In fact, it allows you to block uploading or downloading and analyze performance stability at any time. By carrying out continuous and exhaustive monitoring, any type of anomaly can be detected in time.
Thanks to the use of BMS (Battery Management System) it is possible to monitor the power and temperature of the cells remotely. The control unit communicates with the vehicle itself and with the charger. Thus, loading or unloading can be blocked in the event of any possible critical situation.
When there is an advanced and meticulous design behind it, this type of technology is key for several reasons:
- Ensures performance stability
- Prevents anomalies and failures
- Perform self-diagnoses
- Has predictive power
Ultimately, with the battery management system you can have complete management of the battery pack.
In this sense, our platform automatically and remotely analyzes all the charge and discharge cycles of the interconnected batteries on a daily basis. This way we can evaluate risks and returns, while anticipating possible incidents, intervening before they occur.
Custom technical design of each battery
There are a series of elements that are essential to achieve an optimal battery design. Thanks to the correct layout and configuration, security](__NCP_TOKEN_1__) can be guaranteed at the level of personnel and technological equipment.
These are the three key aspects for an adequate technical design:
1. Comply with the criteria established by European regulations regarding battery safety: electrical and electromagnetic
3. Mechanical study of the integrity of the battery itself, evaluating cases such as tensions or vibrations during normal use
5. Continuous monitoring of operation with the BMS system, with active and passive safety elements, such as fuses and protection components that prevent incidents at any stage
Over the years, NCPOWER has been able to ensure maximum safety for its batteries by working on these same aspects: selecting the proper lithium chemistry, properly assembling the battery pack, and developing a proprietary electronic control unit.
Working in the industrial market, together with several European OEMs, has allowed us to create customized batteries, developing a concept of efficiency and safety that adapts to the spaces and volume of the vehicle in question, offering ad hoc power and capacity to satisfy work requirements.### Avoid overheating
One of the crucial aspects that must be controlled is overheating, and this involves continuous monitoring of the internal temperature of the battery.
Therefore, NCPOWER battery packs have several sensors in each cell that are strategically placed and distributed. Its objective is to be able to measure the temperature and communicate with the vehicle to block the load in case of criticality. Additionally, the resistance of the contacts is controlled. Thanks to this remote control, incidents are prevented and maximum battery life is guaranteed.
In 2022 our percentage of incidents per kw manufactured was 0.0001%. This allows us to guarantee our clients maximum Confidence and Security. We call it the 4 rings of NCPOWER.

Appropriate regulations and certifications
Batteries must undergo rigorous testing and certification to ensure they meet relevant safety and performance standards.
An important factor to consider is UL certification or, at a minimum, ensuring that the battery is designed to UL (Underwriters Laboratories) standards.
UL standards are used to evaluate and certify the safety of a wide range of products and systems, including lithium batteries.
Correct maintenance and use
Batteries should be stored and handled properly to minimize risks of damage, such as storage in cool, dry locations and careful handling.
NCPOWER Manufacturer's Role in Safe Lithium Batteries
Why is it so important to choose a reliable lithium battery manufacturer? Here are some of the key points that make the difference:
- Makes sure to use top quality materials from the main global suppliers.
- Complies with European safety standards regarding electrical and electromagnetic systems
- Follows rigorous manufacturing processes to minimize the risks of failures and dangers.
- Conducts continuous testing and certification of its products: insulation tests, abuse tests to see the behavior of the battery at the limit, etc.
- It has safety protocols for the storage, transportation and use of batteries.
- It has a BMS monitoring system that allows you to control the internal temperature of the battery, preventing overheating.
- Provides customers with clear and detailed information on specifications, performance and safety precautions for their batteries.
NCPOWER battery safety for electric vehicles: a referenceAt NCPOWER we manufacture lithium batteries in Spain with all the key safety aspects mentioned. We provide our clients with unique guarantees.
- We have a BMS monitoring system
