The utility model provides an inverter and an electric vehicle. The inverter comprises a control module, a box body, a first drive module, a second drive module, a heat radiator and a shield plate; and the control module is electrically connected with the first drive module and the second drive module, the heat radiator is arranged at the bottom of the box body, the first drive module and the second drive module are crosswise arranged on the heat radiator at intervals, the shield plate is arranged on the first drive module, and the control module is arranged on the shield plate. So the inverter is compact in structure, and requirements of the electric vehicle can be met in the aspect of size, i.e., the inverter is lower in vertical height and can arranged in the electric vehicle well. And the inverter employs a manner that the two drive module share one box body, so two motor can be respectively driven, and performance of the inverter is improved.
