BATTERIE

Lithium-Ion batteries – equipped with Sony and Samusung Cells

Wayel’s Lithium-Ion batteries offer stability and safety during the phases of production and following use.
For this kind of batteries, intercalation electrode materials are used (that is they accept Lithium Ions inside their structure), which can accumulate, and reversibly great quantities of Lithium are released. The kind of electrode and electrolytic materials determines the working voltage of the individual cells, and has effect on the specific energy of the cells. Wayel’s Lithium-Ion batteries are equipped with Sony cells (except the batteries belonging to the line Trilogy 2.0, these ones are Lithium-Ion batteries – equipped with Samusung Cells). Wayel batteries are 24V (SMALL PLUS and MEDIUM) and 36V (SHORT and MEDIUM), available in different sizes of power and weight.
Recharge time is from 4 to 7 hours. If the battery is kept correctly, Sony and Samsung cells ensure, after 1000 cycles, a residual capacity equal to 80% of nominal capacity (87% after 500 cycles).

Lithium Polymer batteries

A quality battery is long-lasting, and needs to be replaced less frequently. Wayel’s Lithium Polymer batteries, with prismatic cells, represent a solution that allows the highest electric performance with the greatest results.
At the basis of the Lithium Polymer batteries there is an advanced technology which make them small and lightweight, resulting in a lower weight for the same capacity, or in a higher capacity for the same weight. The result is just an increase in the bike’s range. Wayel Lithium Polymer batteries are 24V and 37 V.
Wayel allows the Customers to choose the battery capacity, by proposing different capacities and weighs, thus permitting to select the range of the electric bicycle according to diff erent route needs.
Wayel’s Lithium Polymer batteries, handy and quickly removable, may be recharged at any time and have no memory eff ect; nevertheless, their performance keeps high (up to 800 cycles of charge and discharge – in conditions of nominal discharge 1C and correct use and storage; 80% capacity after 800 cycles of charge). Moreover, also during charge process, they ensure an energy effi ciency of 95%.

Safety above all

All Wayel’s batteries ensure safety as they are in accordance with to law UN38.3: Wayel’s batteries are submitted to the tests UN38.3. Precisely because they are lightweight and compact, all Wayel batteries can be easily be carried with you, so reducing the danger of theft.

All cases of Wayel’s batteries are characterized by a packing design improved in its appearance and dimension: the weight is reduced and the most suitable shape is given tothe battery case.

Test – Norma UN38.3

Find out some some battery tests required by Standard UN38.3, which guarantee the high standards of safety of Wayel batteries Wayel:

38.3.4.1 - Test 1: Altitude simulation

This test simulates air transport under low-pressure conditions. The batteries are tested for at least 6 hours under temperature conditions of 20° C + -5° C and pressure conditions of 0.116 bar or less.

38.3.4.2 - Test 2: Thermal test

This test simulates rapid and extreme temperature changes in order to verify the integrity of the electrical circuits, the connection and the battery itself. The batteries are tested for at least 6 hours under temperature conditions 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.

38.3.4.3 - Test 3: Vibration test

This test simulates various types of typical vibrations during transport. The battery is subjected to a continuous vibration, ranging from 7Hz to 200Hz, for15 minutes. The cycle is repeated 12 times, for a total of 3 hours.

38.3.4.4 - Test 4: Shock test

This test simulates possible impacts during transport. The battery is subjected to an acceleration of 150 g, with a duration of 6 ms.

38.3.4.5 - Test 5: External short circuit test

This test simulates an external short circuit. The battery is subjected to a short circuit condition with a total external resistance of less than 0.1 ohm at 55°C for one hour. After having passed the test, the battery is observed for an additional six hours.

38.3.4.6 - Test 6: Impact test

This test simulates an impact with a given mass. The battery is subjected to an impact against a 15.8 mm diameter bar with a weight of 9.1 kg. The bar is placed at a height of 61 cm above the battery and is dropped onto its centre.

38.3.4.7 - Test 7: Overcharge test

This test evaluates the battery’s ability to withstand an overcharge condition. The battery is charged using a current equal to twice the maximum continuous charge current indicated by the Manufacturer.
