1. PRBA-COSTHA Project for Securing Shock Data on Large Lithium ion Battery Shipments

2. T4 Shock Test Purpose: “simulate possible impacts during transport”
150 g and 50 g forces far exceed severe transport conditions
Review of available test shock data from transport
Review of lithium battery testing standards
Industry plans for securing additional shock data

3. Comparison of Shock Tests

4. PRBA and COSTHA Data Analysis and Project
Data logger
Engine shipment was selected for test as surrogate for battery shipment
Engine has similar weight and uses similar mounting and support during transport
Acceleration (G)
+2.93/-2.49
+2.19/-0.58
+1.51/-0.40
+0.55/-1.45
+0.33/-1.30
