Embodiment approach 1
[0051] The energy storage element S1 in the energy storage unit adopts a single energy storage element such as a battery or a super capacitor; the first single-pole double-throw switch K1 and the second single-pole double-throw switch K2 are composed of mechanical contacts of a relay; the first voltage detection line A1 and the second voltage detection line A2 are cables with a shielding layer; the first output line O1 and the second output line O2, as well as the first recombination connection line B1 and the second recombination connection line B2 are copper wires or aluminum stranded wires.
[0052] The energy storage element SB1 in the backup energy storage unit adopts the same energy storage element monomer as the energy storage unit; the first backup single-pole double-throw switch KB1 and the second backup single-pole double-throw switch KB2 are composed of mechanical contacts of the relay; the first The backup voltage detection line AB1 and the second backup voltage det...
Embodiment approach 2
[0071] When the capacity of the energy storage device is large and a large number of energy storage elements such as batteries or supercapacitors are required to be connected in series or parallel, in order to reduce the cost, the energy storage element S1 in each energy storage unit can use several energy storage elements. Body series, parallel structure.
[0072] Others are the same as the above embodiment.
Embodiment approach 3
[0074] All SPDT switches in the energy storage device can be replaced by power electronic devices, such as IGBT, MOSFET, etc. Others are the same as the above embodiment.
