BATTERY CHARGING METHOD FOR AN ELECTRIC GOLF CAR
First Claim
1. A method of charging a battery used in an electric golf car in which a charger and a vehicle body of the electric golf car are connected together with a connector, the vehicle body including a first CPU that determines if the battery positioned in the vehicle body is being charged and the charger including a second CPU that transmits a charging signal that indicates that the battery is being charged, the first CPU and the second CPU being connected together by a connection cable at the connector, the method comprising:
- generating a periodicity in the charging signal such that the charging signal repeatedly alternates between an ON signal and an OFF signal, anddisabling movement of the vehicle body with the first CPU only if the periodicity of the charging signal is retained.

Abstract
A charger and a vehicle body battery are connected together via a connector. The vehicle body includes a first CPU that determines if the vehicle body battery is being charged or not. The charger includes a second CPU that transmits a charging signal to indicate that the vehicle body is being charged. The connector connects the first CPU and the second CPU. The battery is charged by the charger. The charging signal has a periodicity with a combination of ON signals and OFF signals. The first CPU disables travel of the vehicle body only while the periodicity of the charging signal is continued.

- 4. An electric golf car and charger combination comprising a battery and a first CPU, a first portion of a connector coupled to the car, a second portion of the connector coupled to a charger, the changer comprising a second CPU and a memory location, the second CPU transmitting a periodic signal to the first CPU while the first portion of the connector and the second portion of the connector are joined, the first CPU preventing operation of the golf car while the periodic signal is transmitted from the second CPU to the first CPU.
