Safety
Like all electrical systems managing high power and voltage, Galvani Power batteries prioritize safety, both from a product and working environment perspectives. This principle is applied in different ways such as:
- Ensuring that the cells work within predetermined intervals, even at maximum performance or in extreme working conditions.
- Ensuring that if an issue occurs, the battery is able to report it and act in such a way as to bring the system back into the safest condition.
Modularity
Modularity is Galvani Power’s key to unlock reduced development times, and scalability for an entire product line while maintaining the best performance. Galvani Power focuses particularly on interfaces modularity for systems and production processes to cut down engineering costs while flawlessly adapting to clients’ solutions.
Integration
Galvani Power does not just offer its finished product, but provides support for the battery integration with the client’s solution. This service stems from our knowledge of both the complexity of the battery and its importance to achieve a system’s best performance. Our proactive approach ensures the best support through the electrification transition.
Control Electronics
To provide the best performance and safety, the lithium battery management system (BMS) plays a key role in all monitoring functions, battery management and control
Thanks to its BMS, Galvani Power batteries can:
- Measure the electrical and thermal quantities of both individual cells and the system as a whole.
- Evaluate the state of charge, energy and health to provide an overview of the battery’s current condition.
- Define and ensure current, power, and voltage delivery within the established limits, as well as the appropriate temperature levels to maintain the ideal safety conditions.
- Manage both charge and discharge phases, while communicating with the system through its control electronics
Chemistry
Battery’s performance depend mostly from the cells’ chemistry. Galvani’s technology, while focusing on LFP and LTO, does not poses any limit to the employment of other chemistries.
The right chemistry is selected according to the client’s requirement, aiming at a solution that delivers either the highest energy density favouring autonomy, or power density favouring performance.
Our top chemistry
LFP
Lithium iron phosphate batteries (lifepo4) are a lithium-ion battery technology that uses electrolyte composed of lithium salts dissolved in organic solvents. Below are some common technical specifications for LFP lithium batteries:
- Energy density range: 90 - 120 Wh/kg
- Rated voltage: 3.2 V
- Lifetime: up to 2,000 / 5,000 charge/discharge cycles depending on operating conditions and manufacturer specifications
- Self-discharge rate: 2 / 3% per month at 20 C°
- Charging temperature: 0 / 45 C°
- Discharge Temperature: -20 / 60 C°
- Safety: less prone to combustion than other lithium batteries
- Environmental Sustainability: do not contain toxic heavy metals such as lead or cadmium and are maintenance-free
The technical specifications of LFP lithium batteries may vary depending on the specific application for which they are designed.
We make them together with the customer according to his needs.
NMC
The combination of Nickel, Manganese and Cobalt, known as NMC (LiNixMnyCozO2), is one of the most widely used lithium battery chemists in the automotive world.
There are several variants of NMC chemistry, differentiated by the proportion of each metal:
- NMC 111: with equal percentage of Nickel, Manganese and Cobalt (33.3% each)
- NMC 622: Nickel predominates (60%), followed by Manganese (20%) and Cobalt (20%)
- NMC 811: has a strong presence of Nickel (80%), with Manganese (10%) and Cobalt (10%) in smaller quantities.
As regards certain technical specifications:
- Rated voltage: 3.6 V
- Gravimetric capacity: 220 Wh/Kg
- Energy density: 500 Wh/l
- Lifetime: up to 2,000 charge and discharge cycles
- Discharge ratio: variable between 2C and 3C
LTO
Lithium titanate (LTO) lithium batteries are a type of lithium-ion battery that uses lithium titanate as an anode.
Here are some of the technical specifications of LTO batteries:
- Rated voltage: 2.4 V
- Specific energy density: about 30-60 Wh/kg
- Specific power density: about 1,000-2,000 W/kg
- Life cycles: up to 20,000 charge/discharge cycles at a discharge depth of 80
- Charging time: about 10-20 minutes for a full charge, depending on battery capacity and charging current
- Operating temperature: -30 C to +55 C
- Safety: LTO batteries are considered to be among the safest lithium-ion batteries as they are less prone to overheating, explosions and fires than other lithium-ion batteries.
LTO batteries are often used in applications where long life, fast charging and increased safety are required. Technical specifications can vary depending on the specific application for which they are designed. We make them together with the customer according to his needs.
Thermal Management
Temperature plays a crucial role in the battery’s management in terms of safety, performance, and lifespan. For this reason, Galvani Power’s batteries are developed to perform both cooling functions, to prevent potential dangerous reactions, and heating ones, to avoid significant battery life reductions.
Monitoring
The battery is the heart of an electric powertrain. For this reason it is extremely important to closely follow its life cycle, for regulatory reasons as well as to provide the client with a complete overview of the product’s performance and the appropriate guidelines on its usage and management.
To deliver this service, Galvani Power’s batteries are gauge constantly all internal performance to avoid risks and optimise lifespan and energy efficiency.
End of life
Galvani Power firmly believes that this technological transition should always go hand in hand with environmental sustainability and never compromise it. For this reason the entire life cycle of the batteries is closely followed thanks to its development taking also into account its usage after the installation, which can later translate into:
- Reuse, whenever the battery is entirely or even partially capable of delivering the required performance, ensuring also significant cost savings.
- Recycling, which entails the battery’s careful disassembly, to recover every resource with the highest possible efficiency, and thus offsetting its production’s carbon footprint.
For knowing more about recycling of battery pack check out the Directive 2006/66/EC of the European Union. In short, the directive aims to reduce the environmental impact of batteries by promoting their collection and recycling and limiting the use of harmful materials.
