VIII ALPRIDE E2 AIRBAG SYSTEM - DESCRIPTION
A- SUPERCAPACITORS
The Alpride E2 Airbag System is the first avalanche airbag that does not use lithium-ion or lithium polymer bat-
teries to fuel the compressor’s electric motor.
The E2 System uses its SuperCapacitors to store energy in the form of an electrostatic field. Unlike traditional batteries, there is no need to
create a chemical reaction to generate energy, allowing the E2 System to release its power faster.
The E2 System’s SuperCapacitors offer several advantages over batteries. They are not sensitive to changes in temperature, delivering the
same performance at - 30°C and + 50°C. This saves weight because there is no need to boost the SuperCapacitors to guarantee outstand
-
ing performance at low temperatures.
While batteries tend to wear out after repeated charges, the SuperCapacitors stay strong. They are guaranteed for 500,000 charging
cycles with a nearly infinite lifespan, clearly superior to the 3- to 5-year lifespan of the average battery.
What’s more, the SuperCapacitors are considered passive electronic elements, so there are no restrictions to travel, nor shipping.
B- THE RADIAL COMPRESSOR
The Alpride E2 Airbag System uses a radial compressor, similar to turbo compressors found in cars. This
design allows for high-speed air flow and inflation pressure equal to compressed air cartridge avalanche airbag systems.
C- BATTERIES
The E2 SuperCapacitors System uses two AA batteries for two primary purposes :
1- to recharge the SuperCapacitors
2- to guarantee that the SuperCapacitors keep their full power, compensating for their slow loss of charge and ensuring several months of
autonomy (see section
IX.C.)
Note : Only alkaline or lithium (AA batteries) should be used (for quick recharging at very low temperatures).
Use brand new, premium quality Alkaline AA / LR6 batteries.
Do not use AA zinc carbon batteries and NiCd or NiMH accumulators (rechargeable). These are often not strong enough to sufficiently
charge the SuperCapacitors.
Depending on the AA batteries technology, recharge and autonomy can vary :
• Alkaline batteries :
– are capable of 1 recharge OR 3 months autonomy of normal use (1.5 month if constantly on).
– it is strongly recommended to change the batteries after 1 recharge of the system.
• Lithium batteries :
– are capable of 3 recharges OR 5 months autonomy of normal use (3 months if constantly on).
– it is strongly recommended to change the batteries after 3 recharges of the system.
IX ALPRIDE E2 AIRBAG SYSTEM - CHARGE AND STATUS
A- RECHARGING THE SUPERCAPACITORS
There are two ways to recharge the SuperCapacitors :
1- Insert the two AA batteries (not included). The SuperCapacitors will be automatically recharged once the batteries are in place.
Depending on the type of batteries and the temperature, charging takes 40-80 minutes.
2- Use the micro-USB-C port (5V – 3A) and the standard micro-USB cable (provided). The USB-C port can be connected to a standard
charger (not included), like those used for cell phones, or to a standard power bank. Depending on the type of charger or power bank,
charging takes 20-40 minutes.
The charging status is indicated by the rapid blinking of the LEDs (4x per second).
The level of charge is indicated by the LED color (see section
X.B.).
Note :
• Before the first use, charge the system with the USB-C port. After prolonged storage without batteries (e.g., over the summer or a new
system), charging the SuperCapacitors will take longer than after inflation. After inflation there is still energy in the SuperCapacitors,
but after prolonged storage without batteries, the SuperCapacitors will be completely empty.
• Charging with the USB-C cable takes priority over the batteries. If the batteries are in place and the cable is connected, charging will be
carried out via the cable without draining the batteries.
• Charging is also possible without batteries using the USB-C cable.
• If the system is charging in OFF mode, the LEDs will not blink but charging will continue.
• The system recharges automatically. If the airbag is inflated, the system will begin to recharge on the batteries or the USB port immediately.
• 2 x AA batteries allow for 1-2 recharging cycles of the SuperCapacitors (depending on the quality of the batteries used and the
charging temperature).
WARNING : DO NOT LEAVE THE USB-C CABLE CONNECTED WHILE USING THE E2 SYSTEM IN THE TERRAIN. AFTER CHARGING IS COMPLETE, REMOVE THE USB-C CABLE.
