Small cart battery, particularly those used in electric vehicles or similar applications, are designed with a range of safety features to ensure their secure operation. Here are some key safety features and standards that small cart battery adhere to:
1. Battery Protection Chips: small cart battery often incorporate battery protection chips like the iCM CM1351, which play a crucial role in ensuring safety by preventing overcharging, overdischarging, and overcurrent situations. These chips provide comprehensive protection features including overcharging protection with 15mV precision, three-stage overdischarge current protection, charge overcurrent protection, battery cell wiring disconnection protection, and NTC thermistor disconnection protection.
2. Battery Management System (BMS): BMS is essential for monitoring the voltage, charging and discharging current, and temperature of each battery cell. It provides functions such as balancing, disconnection protection, overdischarging current protection, short-circuit protection, and over-temperature protection. This system ensures that the battery operates within safe parameters and helps prevent thermal runaway and other potential hazards.
3. Safety Standards Compliance: small cart battery must comply with various safety standards such as UL 1642:2020, which covers the safety of primary and secondary lithium batteries. Other standards include IEC 62619:2022, which sets safety requirements for secondary lithium cells and batteries for industrial applications, and IEC 63056:2020, which outlines product safety requirements and tests for secondary lithium cells and batteries used in electrical energy storage systems.
4. Thermal Runaway Protection: Standards like UL 9540A:2019 evaluate how batteries behave during thermal runaway and their fire and explosion hazard characteristics, which is crucial for the design of fire and explosion protection for the installation.
5. Physical Protection and Storage: small cart battery are designed with mechanical protection to resist impacts and vibrations. They should be stored in cool, dry conditions, away from sources of heat or ignition, and protected from extreme temperatures. Storage areas should be bunded with impermeable surfaces to retain any contaminated run-off.
6. Emergency Response Equipment: It is recommended that storage areas for small cart battery are fitted with emergency response equipment specific to the risks inherent to lithium, including suitable fire extinguishing media such as CO2, sand, vermiculite, copper powder, and sodium bicarbonate.
7. Fireproof Containers for Damaged Batteries: If a battery is assessed as damaged or compromised, it should be placed in a fireproof container, such as one filled with non-conductive material like sand or vermiculite.
8. Segregation of Different Chemistry Types: Batteries of different chemistry types should be stored separately to prevent cross-contamination and risks associated with different processing needs.
9. Safety Data Sheets: All personnel should have access to the relevant Safety Data Sheets for each battery kept in storage, and this information should be kept in an easily accessible location outside the storage building.
These safety features and guidelines help ensure that small cart battery are used safely and reduce the risk of accidents, making them a reliable power source for various applications.
