Abstract :
This paper presents the switching super-capacitor balancing methods on robot power system, which is active balancing the charge of cells in a series connection cells strings. It is low losses, simple, and compact in size, which is easy from photo type implement to practical application. The equivalent switching resistor of super-capacitor balancing circuit is deduced for Simulink Simulation. The simulation and test results are illustrated to show the efficacy of the proposed scheme. The super-capacitor and the lithium battery has the complementary characteristics, the analysis of the characteristics between the super-capacitor and lithium battery is introduced. The simulation of this power system reveals to achieve the very good effect under pulse load on robot, the super-capacitor not only absorb massive surging power to lighten burden of the lithium battery but also on switching for balancing, the control board with super-capacitor is realized for practical installing on robot. The simulation and experimental results show that this method can realize practical equalization, and has higher application value.
