CONTROLLING OPERATION OF AN INDUSTRIAL VEHICLE BASED ON BATTERY WEIGHT
First Claim
1. A method for controlling an industrial vehicle that has normal operating characteristics, said method comprising:
- reading a battery weight value from an electronic memory attached to a battery;
comparing the battery weight value to a specified battery weight value for the industrial vehicle; and
limiting operation of the industrial vehicle to less than the normal operating characteristics when the battery weight value is less than the specified battery weight value.

Abstract
Operation of an industrial vehicle, such as one that lifts and transports loads, is controlled based on the weight of a removable battery. A control method involves reading a battery weight value from an electronic memory attached to a battery. That battery weight value is compared to a specified battery weight value for the industrial vehicle. The operation of the industrial vehicle is restricted to less than the normal operating characteristics when the battery weight value is less than the specified battery weight value. For example, the height to which a load can be raised is limited or the speed at which the industrial vehicle is limited when a battery installed on the industrial vehicle weighs less than the specified battery weight for effectively counterbalancing a load.

7. A method for controlling an industrial vehicle that has normal operating characteristics, said method comprising:
-
reading a battery weight value from an electronic memory attached to a housing that contains a battery; transmitting the battery weight value from the battery to a controller on the industrial vehicle; the controller comparing the battery weight value to a specified battery weight value for the industrial vehicle; and limiting operation of the industrial vehicle to less than the normal operating characteristics when comparison of the battery weight value to a specified battery weight value indicates that the battery weighs less that is desired for the industrial vehicle. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
