Light Weight 12S Battery – Design rules for Li-Ion Batteries in UAVs

Andrey — Mon, 30 Oct 2023 14:43:58 +0000

Introduction: Light Weight 12S Battery

Drones, or Unmanned Aerial Vehicles (UAVs), require batteries – as lightweight as possible, yet powerful – to ensure optimal performance and longer flight times.

The need for lightweight batteries is crucial, as the weight of the battery significantly impacts the drone’s payload capacity, maneuverability, and energy efficiency.

Moreover, the battery & it’s designed &electronics will also affect the ability of the end-user to use the full potential of the battery.

Light Weight 12S Battery

Over the years Amicell – Amit Industries ltd designed numerus batteries for UAVs – from Li-Ion 12S batteries to LiPo 6S (Pouch).

Most of them with very strict demands for weight & volume.

Below, we’ll show the basic guidelines is order to achieve the best battery designs for your drone. We will use, as an example, a typical Battery designed in our factory – Li-Ion 12S 30Ah.

Be as accurate as possible when it comes to system requirements.

Voltage range: the higher the voltage the lower the current and the wiring is thinner. It used to be more 6S & 7S LiPo batteries. Today a lot of UAVs are using Li-Ion 12S battery and above. 12S Voltage – This 12S battery has a max voltage of 50.4V for 4.2V cells & up to 51.6V for high Energy density batteries.
On the other hand – Charging system and balancing become more complex and so will the optional Battery Management System (see paragraph 3d).
Discharge profile: In most Li-Ion battery technologies Higher Energy density comes with lower discharge power. So, taking high safety factor will make the designer choose heavier battery, thicker wiring and more complex connector.
For example: there are on-line 40C LiPo Batteries, but for a 12S LiPo battery with capacity of 30Ah that means your system requires ~50KW. Not a lot of applications need that high power in a battery that weighs only ~7Kg, so if your system requires less, you will receive lighter battery.

Determine target weight.

The easiest thing is to say – I want the minimum weight. The problem is that “minimum weight” may come with high price and lower reliability.

If we will look at our case study:

Li-Ion Polymer 12S 30Ah (H320Wh/Kg series) Minimum weight with minimum casing: ~4.3Kg

Li-Ion 12S 30Ah Minimum weight with minimum casing: ~5.2Kg

The weight of the LiPo 12S battery can be 17% lower than the Li-Ion 12S. But there will be a price in cycles and in price.

Determine Battery max dimensions

The easier it is to assemble the easier it will be to reduce weight! Batteries with “Box” shape are usually simple to assemble and require less wiring, less tooling and less structure/casing.

When it comes to dimensions there are advantages to Li-Ion over Li-Ion Polymer Batteries. For start – Li-Ion has lower energy density but higher volume density.

On the other hand, one of the key disadvantages of Li-Ion is that, for now, there are only two popular cell dimensions: 18650, 21700. That means (1) batteries that are too narrow (less than 19mm) practically don’t have Li-Ion option and (2) if the battery was not designed in parallel with the UAV itself it will probably will not have max volume efficiency.

Decide the level of safety & Telemetry your battery will hold. Some options:

No Internal safety – No Fuses on main power line. No safety circuits. Telemetry – Battery Voltage only.
Safety only while charging via the Discharge and Balance harnesses – connection to external safety circuits with over-charge protection. This is the level of safety received in most UAV batteries purchased on-line.
Fuses on main power line and on Balance lines. Telemetry – Battery Voltage only.
Safety against over-charging and external short-circuits. Connecting the Discharge and Balance harnesses to safety circuits with over-charge protection.
Fuses on main power line and on Balance lines, PCM on charging line only. Telemetry – Battery Voltage only.
Safety against over-charging and external short-circuits. The PCM supply over-charge protection and low current internal balancing so the end-user can use different chargers.
BMS system – Full Telemetry by communication – SMBus / I2C / CAN etc.
All safety decisions – according to algorithm.
Here “the sky is the limit”. The communication system in the battery will be able to send on-line data regarding battery status. The operator will be the one deciding what to do.
The “heart” of this BMS system is based on microchips of companies like TI and there are microchips suitable for Li-Ion batteries of 12S and above.

The thing to remember – The highest the safety the more complex the battery becomes and so will its design process and the need for maintenance.

It is not uncommon that while developing a proto-type the Safety features are kept to a minimum in order to first proof feasibility of the solution, while the BMS is developed in parallel.

Identify key performance parameters.

In other words – In case of a dilemma, what will be more important – energy density (& weight) / Power density / Lifecycle / Price

Casing

From the most basic (Heat shrinkable sleeve) to the most unique (3D Kevlar).

There are 4 reasons for casing of batteries:

Safety – reducing risk of tempering with the battery, basic safety against drop, preventing mechanical load on electrical components & wiring etc.
Larger & heavier batteries need casing to prevent internal mechanical stress on the cells and on electrical connections. For example: a 12S Li-Ion battery with capacity of 30Ah will weigh ~5Kg and assembled for 72 cells. These cells can be assembled in a narrow formation, that fits a UAV fuselage, with a length that can exceed 60cm. This narrow and long battery will need casing to prevent it from deform under its own weight.
Making the product Proof from mistakes. The battery dimensions will be uniform. The end-user cannot insert or use it in un designed manner. Easier to verify correct insert of connectors.
Commercial – The product will look much better. Indications of battery status are visible. It is harder to copy or buy elsewhere.

However, casing will also add NRE costs + increase price and to the weight.

The charger

When talking about UAV’s it will be better to refer it as Charging + Balancing system. The charging system is, in most cases, external. The balancing system can also be external or internal in the battery.

The charger will charge according to CC-CV charging method – constant current (CC)
till max charging voltage followed by maintaining that voltage at a constant level (CV), while the charging current gradually decreases.

The Balancer will (1) verify no single cell / string will pass the max allowed voltage (safety) and (2) will verify all cells are in the same voltage level.

The Balancing process is usually based on discharging the highest cell via a resistor. This process generates heat. The balancing current is set according to the resistor selected and the ability to disperses this heat. This is why internal circuits has limited balancing current (usually 50-200mA) while in external balancing, that can use large resistors + fans, the current can be much higher (~500-700mA). So, the advantages of external balancing are (1) smaller internal circuit and (2) potential longer life of the battery due to more efficient balancing. The disadvantages are (1) you need more pinouts in the battery connectors and (2) the charger needs to be with balancing option.

Choosing The Best 12S Battery

In Summary, The Best Battery is the One that Maximize system performance, as you understand them.

The challenge was never to supply the max energy density or the max cycles or the Safest battery rather how to supply the right “mixture” of these characteristics that will be optimal performance under the required operational profile.

The Li-Ion 12S refers to the arrangement of the battery cells. In a 12S battery, twelve cells are connected in series, enhancing the overall voltage ~44V with max voltage of 50.4V for 4.2V cells & up to 51.6V for high Energy density batteries, Like Amicell line H300 -H320Wh/Kg cells (Li-Ion Polymer).

This configuration enables the delivery of the power required for drones to achieve longer flight times and improved performance, thereby aligning with the stringent demands of both recreational and professional drone applications.

12S LiPo Battery

Li-Ion Polymer (12s lipo) batteries, derived from the broader Li-Ion (Lithium-Ion) family, bring forth a lighter and more flexible energy storage solution.

These batteries employ a polymer electrolyte instead of the typical liquid found in other Li-Ion batteries. This shift not only reduces weight but also allows for thinner, flexible, and more varied form factors, making them
