Recent researches of the novel 4D Einstein–Gauss–Bonnet (EGB) gravity have attracted great attention. In this paper, we investigate the validity of the weak cosmic censorship conjecture for a novel 4D charged EGB black hole with test charged scalar field and test charged particle respectively. For the test charged field scattering process, we find that both extremal and near-extremal black holes cannot be overcharged. For the test charged particle injection, to first order, an extremal black hole cannot be overcharged while a near-extremal 4D charged EGB black hole can be destroyed. To second order, however, both extremal and near-extremal 4D charged EGB black holes can be overcharged for positive Gauss–Bonnet coupling constant; for negative Gauss–Bonnet coupling constant, an extremal black hole cannot be overcharged and the validity of the weak cosmic censorship conjecture for a near-extremal black hole depends on the Gauss–Bonnet coupling constant.

新型4 D爱因斯坦-高斯-帽子（EGB）引力的最新研究引起了极大的关注。在本文中，我们研究了一个带有测试带电标量场和测试带电粒子的新型4D带电EGB黑洞的弱宇宙检查猜想的有效性。对于测试的带电场散射过程，我们发现极端和接近极端的黑洞都不能被过度充电。对于测试带电粒子的注入，首先，一个极端的黑洞不能被过度充电，而几乎极端的4 D带电的EGB黑洞可以被破坏。然而，至二阶，极值和接近极值的4 D带电的EGB黑洞可以过高充电，以实现正高斯-贝纳特耦合常数；对于负的高斯-贝纳特耦合常数，极黑洞不能被过度充电，弱的宇宙检查猜想对于接近极端的黑洞的有效性取决于高斯-贝纳特耦合常数。
