In view of the test failure caused by the explosion of the battery module of the bomb-borne storage test device under high g-value impact,several batteries commonly used in the test device were selected and their anti-high g-value impact performance was tested under different directions(parallel and vertical impact directions)and paraffin filling by Hopkinson rod.The results show that the battery with redundancy design has high impact resistance.Under the acceleration impact of about 300,000 g,the tested batteries did not explode.At present,the reliability of the battery can be guaranteed within the range of the acceleration amplitude of the projectile body penetrating various targets.
