BS EN 50342 Automotive Lead-Acid Starter Battery Testing
The BS EN 50342 standard is specifically designed to ensure that automotive lead-acid starter batteries meet the stringent requirements for performance, durability, and safety. This standard applies primarily to starting, lighting, and ignition (SLI) batteries used in various vehicle types including passenger cars, motorcycles, trucks, and buses.
The testing protocol under this standard is comprehensive, covering a range of critical parameters such as cold cranking current (CCC), reserve capacity (RC), and high-rate discharge performance. These tests are crucial for ensuring the reliability and safety of automotive batteries in challenging environmental conditions like extreme temperatures. The CCC test measures the maximum amount of electrical current that a battery can provide at 0°C, which is essential for starting an engine quickly under cold conditions.
The reserve capacity test evaluates how long a battery can power essential vehicle functions such as headlights and radio after it has been completely discharged by a starter motor. This ensures that the battery provides sufficient power to maintain vehicle safety features during prolonged start attempts or in case of alternator failure.
The high-rate discharge performance test assesses the battery's ability to deliver current at a rapid rate, which is vital for starting large engines and heavy-duty vehicles. The testing process involves precise measurement techniques and controlled environmental conditions to ensure accurate results.
For each test, there are specific methodologies that must be followed strictly. For instance, the CCC test requires the use of a specialized bench-top tester capable of simulating real-world engine start conditions. Similarly, the reserve capacity test is conducted using standardized discharge equipment that can accurately measure current draw over time.
Preparation of specimens for testing includes ensuring the battery is fully charged and at ambient temperature before any tests are performed. This ensures consistent and reliable results across multiple samples. The instrumentation used in these tests includes advanced data acquisition systems capable of recording all relevant parameters during each test cycle.
The BS EN 50342 standard also specifies detailed acceptance criteria for all tested parameters. A battery must pass all specified tests to be certified as compliant with the standard. Compliance ensures that automotive lead-acid batteries meet the necessary performance and safety standards, enhancing vehicle reliability and reducing the risk of breakdowns.
| Parameter | Description | Acceptance Criteria |
|---|---|---|
| Cold Cranking Current (CCC) | The maximum current a battery can provide at 0°C. | Must meet or exceed the specified value for the battery's capacity rating. |
| Reserve Capacity | The time in minutes that a fully discharged battery will run essential vehicle functions. | Must be at least as long as required by the standard, typically 45 to 90 minutes depending on the battery's capacity. |
| High-Rate Discharge Performance | The ability of a battery to deliver current at a rapid rate. | Must demonstrate sufficient power output as specified in the standard for different capacities. |
Applied Standards
The BS EN 50342 standard is complemented by other relevant international standards such as ISO 6819, which provides additional guidance on the design and construction of lead-acid batteries. These standards work together to ensure that automotive lead-acid starter batteries are not only reliable but also safe for use in various vehicles.
The BS EN 50342 standard specifically addresses the performance requirements for SLI batteries used in cars, motorcycles, trucks, and buses. It covers a wide range of tests including those mentioned earlier such as cold cranking current, reserve capacity, and high-rate discharge performance. Compliance with these standards is essential for manufacturers to ensure their products meet regulatory requirements.
