Abstract

The invention discloses a semi-closed power supply device for a solar electromobile. A storage battery (9) outputs a direct current to a motor (11) through a DC / DC (Direct Current / Direct Current) inverter (1). A motor drives wheels to rotate. A first charging circuit of the storage battery is in a structure such that an alternating current power supply (7) connected with an AC / DC (Alternating Current / DC) inverter (8) is connected with the storage battery. A second charging circuit of the storage battery is in a structure such that the output of a solar panel (1) connected with a solar battery controller (2) is connected with an input end of a first direct current center wiring board (3). The output end of the first direct current center wiring board connected with a first switch (5) is connected with the storage battery. The output end of the first direct current center wiring board is respectively connected with a direct current load (12) and a DC / AC inverter (13). The storage battery connected with a second switch (6) is connected with a second direct current center wiring board (4). The output end of the second direct current center wiring board is respectively connected with the direct current load and the DC / AC inverter. The output end of the DC / AC inverter is connected with an alternating current load (14).

Description

technical field [0001] The invention relates to an electric vehicle, in particular to a power supply device for a solar electric vehicle. Background technique [0002] An electric vehicle is a vehicle that uses electricity as its power source. It uses a battery as an energy source and is equipped with a motor, controller, battery, operating components and display instrument system. It is a mechatronic vehicle. The power supply unit of electric vehicle is the power unit of electric vehicle, and existing electric vehicle power supply unit comprises storage battery 9, DC / DC inverter 10, motor 11, see figure 1 The battery 9 outputs a DC power supply to the motor 11 after passing through the DC / DC inverter 10, and the motor provides a power source to drive the wheels to rotate and drive the vehicle to run. Horn use. Existing accumulator pack is to adopt 220v AC power source 7 to charge accumulator through AC / DC inverter 8. Some batteries use lead-acid battery packs, and so...
