Abstract

The backup power supply of the present invention is adapted for a vehicle, which has a power system. The backup power supply includes a motor electronic appliance and a battery. The motor electronic appliance is installed in the vehicle and electrically connects to the power system of the vehicle. The battery electrically connects to the motor electronic appliance, such that the battery can receive electric power from the power system or can supply electric power to the power system. As such, the backup power supply supplies backup power to the power system during the replacement of the motor lead-acid battery.

Claims

1. A backup power supply for a vehicle, the vehicle having a power system, the backup power supply comprising

a motor electronic appliance, having a connector electronically connecting the motor electronic appliance with the power system of the vehicle;

a battery, electronically connecting to the motor electronic appliance.

2. The backup power supply of claim 1, further comprising a means for switching the battery between a charging state and a discharging state, when the battery being at the charging state, the battery receiving electric power from the power system, when the battery being at the discharging state, the battery supplying electric power to the power system.

3. The backup power supply of claim 1, wherein a protective circuit board is disposed on the motor electronic appliance or the battery to prohibit the battery from over-charging or over-discharging.

4. The backup power supply of claim 1, wherein the battery is a rechargeable battery.

5. The backup power supply of claim 4, wherein the rechargeable battery is a lithium iron phosphate battery.

6. The backup power supply of claim 4, wherein the rechargeable battery is a nickel metal hydride battery.

7. The backup power supply of claim 4, wherein the rechargeable battery is a nickel cadmium battery.

8. The backup power supply of claim 4, wherein the rechargeable battery is a lithium ion battery.

9. The backup power supply of claim 1, wherein the motor electronic appliance is pluggable into a cigar-lighter socket of the vehicle.

10. The backup power supply of claim 5, wherein the lithium iron phosphate battery has an anode being made from vanadium, manganese or cobalt.

11. The backup power supply of claim 8, wherein the lithium ion battery has a cathode being made from LiCo_1/3Ni_1/3Mn_1/3O₂.

12. The backup power supply of claim 8, wherein the lithium ion battery has a cathode being made from LiCoO₂.

13. The backup power supply of claim 8, wherein the lithium ion battery has a cathode being made from LiMn₂O₄.
