Abstract
An electrical bicycle electrical system includes a battery, various accessories and an electrical power distribution module. The electrical power distribution module includes a control device, various accessory modules and a voltage convertor module. The electrical power distribution module operates to convert the bicycle battery voltage to the corresponding voltages of the bicycle accessories which are commonly lower than the battery voltage. The electrical power distribution module adapts to a variety of different bicycles, manufactured by different manufacturers, allowing users to replace the manufacturer's engine control unit to fit their application.
Claims15
An electric bicycle electrical system comprising:
- (a) a battery operative to provide electrical power at a battery voltage to the electrical system;
- (b) two or more accessories;
- and
- (c) an electrical power distribution module connected to and in communication with the battery and the two or more accessories, said electrical power distribution module comprising:
- (i) a control device;
- (ii) two or more accessory modules coupled with the two or more accessories and operative to provide electrical power to the two or more accessories at two or more accessory voltages;
- and
- (iii) a voltage convertor module;
- wherein the control device senses a battery signal from the battery indicative of the battery voltage, via a battery sense line, and two or more accessory signals from the two or more accessory modules indicative of the two or more accessory voltages, via two or more accessory sense lines, and converts the battery voltage to the two or more accessory voltages, via the voltage convertor module.
An electrical power distribution module for an electric bicycle electrical system, said electrical system comprising a battery operative to provide electrical power at a battery voltage to the electrical system and two or more accessories, wherein the electrical power distribution module is connected to and in communication with the battery and the two or more accessories, said electrical power distribution module comprising:
- (i) a control device;
- (ii) two or more accessory modules coupled with the two or more accessories and operative to provide electrical power to the two or more accessories at two or more accessory voltages;
- and
- (iii) a voltage convertor module;
- wherein the control device senses a battery signal from the battery indicative of the battery voltage, via a battery sense line, and two or more accessory signals from the two or more accessory modules indicative of the two or more accessory voltages, via two or more accessory sense lines, and converts the battery voltage to the two or more accessory voltages, via the voltage convertor module.
A method of controlling an electric bicycle electrical system, said electrical system comprising a battery operative to provide electrical power at a battery voltage to the electrical system, two or more accessories, and an electrical power distribution module connected to and in communication with the battery and the two or more accessories, said electrical power distribution module comprising a control device, two or more accessory modules coupled with the two or more accessories and operative to provide electrical power to the two or more accessories at two or more accessory voltages, and a voltage convertor module, said method comprising:
- (i) sensing a battery signal from the battery indicative of the battery voltage, via a battery sense line;
- (ii) sensing two or more accessory signals from the two or more accessory modules indicative of the two or more accessory voltages, via two or more accessory sense lines;
- and
- (iii) converting the battery voltage to the two or more accessory voltages, via the voltage convertor module.
