HIGH QUALITY STANDARDS. BATTERIES GUARANTEED
THE BATTERIES OF ITALWIN ELECTRIC BIKES HAVE BEEN VERY CAREFULLY CHOSEN, AFTER SELECTING THE BEST ITALIAN SUPPLIERS ON THE MARKET, TO OFFER ONLY HIGH QUALITY PRODUCTS.
The electric bikes have the most advanced batteries: Lithium Ion, equipped with Samsung cells to guarantee greater quality, safety and long life thanks to numerous charging cycles: up to 1,000 complete cycles.
COMPLY WITH UN38.3
The batteries comply with the legislation UN38.3 providing numerous tests (altitude, heat, vibration, impact, overload, etc.) many of which are relevant to safety. Passing the tests UN38.3 is the mandatory requirement to market the batteries individually and apart from the e-bikes. This allows the customer to choose batteries of different capacities and suitable to his route needs. Moreover, the customer has also the guarantee to purchase them, at a later time as spare parts, due to normal selling out. Moreover, ITALWIN offers you the possibility to extend the warranty of your battery up to 3 years* (valid for the Italian market).
* The warranty terms and time will very depending on the country where the product was sold.
TEST – NORMA UN38.3
Here are some examples of battery tests required by UN38.3 legislation, which guarantee the high safety standards of Italwin batteries:
126.96.36.199 - Test 1: Altitude test
Simulation of air transport with low pressure conditions. The batteries are tested for at least 6 hours under the following conditions: temperature of 20 °C + -5 °C; pressure of 0.116 bar or less.
188.8.131.52 - Test 2: Heat test
Simulation of quick and extreme temperature changes to verify the integrity of the electric circuits, connections and battery itself. The batteries are tested for at least 6 hours under the following conditions: temperature of 75 °C + -2 °C and within a maximum time of 30 min. the test is repeated under temperature conditions of -40 °C + -2 °C. The test is repeated 10 times.
184.108.40.206 - Test 3: Vibration test
Simulation of different types of vibrations typical of a transport. The battery is subjected to a vibration that goes from 7Hz to 200Hz continuously for 15 minutes. The cycle is repeated 12 times for a total of 3 hours.
220.127.116.11 - Test 4: Shock test
Simulation of possible impacts during transport. The battery is subjected to an acceleration of 150 g of the duration of 6 ms.
18.104.22.168 - Test 5: External short circuit test
Simulation of a short circuit deriving from outside. The battery, placed in an environment at 55 °C, is subjected to a short circuit with a maximum resistance of 1 ohm for 1 hour. After passing the test, the battery is kept under observation for 6 hours.
22.214.171.124 - Test 6: Impact test
Simulation of a collision with a given mass. The battery is subjected to an impact against a 15.8 mm diameter bar having a weight of 9.1 kg, which placed at 61 cm in height as to it, is dropped at the center of the sample.
126.96.36.199 - Test 7: Overload test
Evaluation of how the battery responds to an overload. The battery is electrically charged with a double current flow as to the maximum current indicated by the manufacturer.
