What is ICE 62619?

IEC 62619:2017 specifies requirements and tests for the safe operation of secondary lithium cells and batteries used in industrial applications including stationary applications.

Safety is the most important for lithium battery, so a safety tests for lithium cells is very necessary. When there is an IEC 62619 standard specifying evaluation requirements and prerequisites of cells used in particular applications and will be in conflict with this record, the former takes precedence. Listed here are a few examples of software that use batteries and cells under this document’s scope. Because IEC 62619 covers, batteries for various industrial uses, it comprises these requirements, which might be typical and minimal to the several software. Electrical safety is included only as part of the risk evaluation of Clause 8.

Regarding details for fixing electrical security, the end-use program standard requirements need to be thought about. This test applies to batteries and cells. If the battery is split into smaller components, the more compact device can be analyzed as the owner of this battery. The producer acknowledges the unit. The maker may add works that exist in the last battery in the unit that is tested.

Types of Battery Test Required for IEC 62619 Standard

Tests for Battery Cells

• Topical Short Circuit Short-Circuit between the negative and positive terminals will not result in a fire or explosion IEC 62619 Cl. 7.2.1 2.
• Impact An effect on the mobile shall not lead to explosion or fire IEC 62619 Cl. 7.2.2 3.
• Drop Test A fall of a mobile or cell block battery system will not result in explosion or fire IEC 62619 Cl. 7.2.3 4.
• Thermal abuse An elevated temperature of a mobile or cell block will not lead to explosion or fire IEC 62619 Cl. 7.2.4 5.
• Overcharge Charging for longer spans than given by the manufacturer will not result in a fire or explosion IEC 62619 Cl. 7.2.5 6.
• Forced Discharge A mobile in a multi-cell program will withstand a driven release without causing a fire or explosion

Types of Tests for Battery Systems

• Propagation/internal thermal event A driven inner short-circuit with at a Mobile won’t lead to the fire of the whole Battery fire, or system transports IEC 62619 7.3.3 2
• Overcharge with voltage The BMS will control the charging voltage cells. IEC 62619 8.2.2 3
• Overcharge with present In case the input to the cells and Batteries surpasses the maximum charging Present of these cells, the BMS shall disrupt the Charging to safeguard the battery system from Risks associated with charging currents above the Cells given maximum charging current IEC 62619 8.2.3 4
• Overheating control, The BMS shall finish charging once the Temperature of these cells and battery Exceeds the upper limit given by the Cell maker IEC 62619 8.2.4 5
• Capacity validation This evaluation determines firsthand the capacity A mobile holds after storage for a protracted period. Second, the capacity which Can be retrieved by a subsequent recharge.

IEC 62619 Test Standard Battery Test Chamber

Thermal Abuse Test Chamber

A security issue of IEC 62619 particular interest is a situation called thermal runaway where a couple of exothermic side reactions happen, resulting in elevated temperature ranges, which in turn cause an uncontrollable and excessive discharge of warmth. This work aims to clarify the impact of the reactions by using a thermal abuse model that forecasts single-cell behavior when exposed to an elevated temperature. The experimental evaluation of the thermal security conduct comprises a constant-power heating component to activate a thermal runaway occasion. This analysis takes a present thermal abuse version and transforms it to emulate the conditions through a constant-power warming evaluation. The outcome is shown to be in agreement with the experimental data to various mobile configurations with the thermal abuse test chamber’s help. The effect of convection illness, mobile physical setup, and electrolyte combustion around the mobile thermal behavior can also be researched.

Traction Battery Drop Tester

• Single Storage Mobile Security Evaluation Drop testing
• Charge the Only storage Mobile Based on IEC 62619 6.1.3
• Reduce the Favorable negative terminals of the Mobile from the Elevation of 1.5m to the concrete floor
• Watch for 1hBattery Module Safety TestCharge the battery module in accordance with the Conventional IEC 62619 6.1.4
• Fall the Favorable negative terminals of the battery in the height of 1.2m to the concrete Ground Watch for 1h

Thermal Runaway Test Machine

Thermal runaway battery test chamber test procedure applies to most RESS-equipped HEV, PHEV, and EV vehicles. For IEC 62619 standard specific guidance was provided for the use of the processes to home-based predicated RESS systems as Li-ion mobile chemistry is your dominant chemistry in RESS in the time of the writing, but the approach provided can be applied to a selection of other mobile chemistries.
The evaluation procedure described consists of 3 components:
   1. Choosing a Proper single mobile thermal runaway initiating methodology,
   2. Verifying the thermal runaway initiation methodology in voucher or module level evaluations
   3. Complete scale; in-vehicle testing to evaluate if one cell thermal runaway inside a RESS can provide a hazard signal for significant automobile accessories.

Large Current Battery Short Circuit Test

A large current battery short circuit test chamber is to assess the electric performance or security of lithium-ion batteries and other secondary batteries consisting of constant charging evaluations, external short circuit evaluations, overcharging evaluations, over-discharging, and large-current evaluations. Topical short circuit tests simulate incorrect battery utilization. These evaluations include short-circuiting a battery from external to simulate usage that might lead to fire or rupture. DGBell can execute external short circuit tests using high currents of around 16 kA (a world-first) and in non – to high-temperature environments. Together with these brief circuit tests, we also supply an extensive selection of testing/certification solutions for compliance with IEC 62619 supply safety testing, evaluation consulting and consulting services for automobile battery packs/modules, and energy storage devices.

Heavy Impact Battery Tester

This heavy impact battery test chamber has gained broad acceptance in analyzing the effect resistance of various lithium batteries. It’s also widely utilized to establish quality management criteria for resistance to affect surface damage and comprehension of several materials.
According to the heavy impact tester, this battery affects the battery’s tester protection via various weights, different heights, and various impact locations. Following a series of evaluations with this particular battery influence tester, the battery shouldn’t have fire or explosion.

Conclusion

IEC 62619 test applies to accept Lithium-ion battery programs utilized in ships and offshore installations classed or meant to be classed with the battery test system. This Classification note supplies requirements for acceptance of Lithium-ion battery systems in battery-powered hybrids or vessels. The setup requirements for Li-ion battery programs such as the applicable IEC 62619 standards and ecological.
