T/ZJXDC 001-2018 Valve-regulated lead-acid batteries for electric assisted bicycles

Scope

Scope: This standard applies to valve-regulated lead-acid batteries (hereinafter referred to as batteries) with a capacity of 30Ah or less, used in electric bicycles, electric scooters, electric unicycles, electric wheelchairs, etc. that use batteries as the main power source. The sulfuric acid electrolyte in the batteries is either adsorbed in the microporous structure between the electrodes or in colloidal form. Main technical contents: 1. **2hr capacity**: The battery shall meet the standard requirements for testing. The 2hr capacity Ca should reach C2 within three cycles. 2. **Battery cycle life**: The battery shall meet the standard requirements for testing. The number of cycles should be no less than 360. 3. **Explosion-proof capability**: The battery shall meet the standard requirements for testing. When exposed to an open flame, it should not ignite or explode internally. 4. **Flame retardancy**: Batteries with flame retardancy requirements shall meet the standard requirements for testing. The battery cover should comply with the V-0 (vertical combustion) requirements in GB/T 2408-2008, Sections 8.4.1 and 9.4; the battery tray should comply with the HB (horizontal combustion) requirements in GB/T 2408-2008. (Batteries with flame retardancy should be clearly marked on the battery or packaging.) 5. **Overcharging**: The battery shall meet the standard requirements for testing. It should not catch fire, explode, or leak electrolyte. 6. **External short-circuit**: The battery shall meet the standard requirements for testing. It should not catch fire, explode, or leak electrolyte. 7. **Mechanical impact**: The battery shall meet the standard requirements for testing. It should not catch fire, explode, or leak electrolyte.
