Prioritizing Your Safety with UL 2271 Compliant Batteries

E-bike battery fires are a serious and growing concern, with recent incidents in White Rock, N.S., and Vancouver causing injuries and fatalities. In the United States, New York City has experienced a significant rise in e-bike battery fires, leading to numerous injuries and deaths. These tragedies often stem from low-quality or unregulated batteries that lack crucial safety features, turning a convenient mode of transport into a dangerous fire hazard.

At Rize Bikes, your safety is paramount. We understand the critical importance of a high-quality battery, which is why we are committed to meeting robust safety standards.

Understanding UL 2271: The Gold Standard for E-Bike Batteries

When it comes to e-bike battery safety, UL 2271 is a key benchmark. Developed by Underwriters Laboratories (UL), a global safety certification organization, UL 2271 is a specific safety standard for lithium-ion battery packs used in Light Electric Vehicles (LEVs), which include e-bikes.

This standard isn't just about a quick check; it involves comprehensive and rigorous testing to ensure the battery pack's safety and performance under various conditions.

Rize's Commitment to UL 2271 Compliance: Key Tests Performed and Passed

Rize 48V 15Ah and 52V 15Ah batteries are now UL compliant with UL 2271. This signifies that our batteries have undergone detailed testing outlined by this rigorous standard.

Here are examples of key tests performed and passed, demonstrating Rize's commitment to safety:

Overcharge Test: This test evaluates the battery's ability to withstand an overcharge condition due to a single fault in the charging control circuitry. Our batteries passed, demonstrating that the maximum charging voltage on the cells did not exceed their normal operating region, and there was no explosion, fire, rupture, or electrolyte leakage.
High Rate Charge Test: This test assesses the battery system's ability to protect its cells against a high rate charge condition at currents exceeding the maximum charging current. Our batteries passed, showing that the protection circuit detected and prevented overcharging, with no non-compliant results such as explosion or fire.
Short Circuit Test: This test evaluates the battery's ability to withstand a short-circuit condition. Our batteries passed, indicating no explosion, fire, rupture, or electric shock hazard occurred.
Overload Under Discharge Test: This test determines if the battery can withstand an overload during discharge. Our batteries passed, demonstrating effective protection against such conditions.
Overdischarge Test: This test evaluates the battery's ability to withstand an overdischarge under a protection circuitry fault condition. Our batteries passed, with no explosion, fire, rupture, or electric shock hazard.
Temperature Test: This test ensures that the battery modules and cells are maintained within specified operating limits during maximum charge and discharge conditions. Our batteries passed, showing proper thermal management and no exceeding of temperature specifications.
Imbalanced Charging Test: This test determines whether a DUT with series-connected cells can maintain cells within their specified operating parameters if it becomes imbalanced. Our batteries passed, with the voltage limits not being exceeded and no hazardous events occurring.
Dielectric Voltage Withstand Test: This test is an evaluation of the electrical spacings and insulation at hazardous voltage circuits within the DUT. Our batteries passed, showing no breakdown of insulation.
Isolation Resistance Test: This test is intended to determine that insulation provides adequate isolation of hazardous voltage circuits from accessible conductive parts of the DUT. Our batteries passed, maintaining sufficient insulation resistance.
Vibration Endurance Test: This test evaluates the DUT's ability to withstand vibration that may occur from its use in an LEV. Our batteries passed, showing no non-compliant results after extensive vibration.
Shock Test: This test is intended to determine whether or not the DUT can withstand a mechanical shock that may occur when in use in an LEV. Our batteries passed, with no hazardous results.
Crush Test: This test is conducted to determine the DUT's ability to withstand a crush that could occur during a vehicle accident. Our batteries passed, with no explosion, fire, or electric shock hazard.
Drop Test: This test is intended to evaluate whether a hazard exists when a DUT is subjected to an inadvertent drop during installation or removal from the vehicle. Our batteries passed, with no damage allowing access to hazardous parts.
Mold Stress Relief Test: This test is intended to evaluate whether any shrinkage or distortion exist on a molded or formed thermoplastic enclosure due to release of internal stresses caused by the molding or forming operation. Our batteries passed, ensuring no exposure of hazardous parts or reduction of electrical spacings.
Roll Over Test: This test is to evaluate whether or not a rotation of an EESA as might occur within an LEV that is turned over could lead to a hazardous condition. Our batteries passed, with no hazardous results after a 360° rotation.
Water Exposure Test (IP Code Rating): This test subjects a fully charged DUT to a water exposure test. Our batteries passed the water exposure test.
Thermal Cycling Test: This test subjects the battery to extreme temperature fluctuations. Our batteries passed, demonstrating resilience to thermal stress.
Label Permanence Test: This test ensures the durability and legibility of safety labels. Our batteries passed, confirming that critical warnings remain clear.

This commitment to UL 2271 compliance means our batteries are designed with robust mechanisms to protect against common failure points, giving you peace of mind on every ride.

Don't compromise on safety. Choose a Rize bike, knowing our batteries have been tested to be compliant with UL 2271, and ride with confidence.
