Description

646252/3 ANTI-THEFT SECURITY SYSTEM AND METHOD FOR VEHICLE WITH DETACHABLE BATTERY CARRIER FIELD OF THE INVENTION The present invention relates to light electric vehicles, such as electric bicycles in particular to detachable batteries therefore.

BACKGROUND OF THE INVENTION An electric bicycle, referred to also as an e-bike, power-bike or booster bike is a bicycle with an integrated electric motor assist which can be used for propulsion. Electric bicycles use rechargeable batteries. The electric bicycle is powered by a manual force of operator and may also receive assist power from the integrated electric motor for assisting the operator's manual propulsion of the associated bicycle.

The classification of electric bicycle is typically decided by whether the electric motor assists the rider using a power-on-demand or by pedal-assist system. Some models even sense pedal pressure and command the motor to deliver more power whenever the rider pedals harder.

The electric bicycle derives the electric power for operating the electric motor from a rechargeable battery. Conventionally, the type of battery utilized includes a battery pack having a number of individual rechargeable cells electrically connected in series. The battery pack is typically contained within an outer container having electrical connector(s) to connect for example with the electric motor and with electric motor controller.

The conventional rechargeable battery may be removed from the electric bicycle for example to recharge the battery in a separate location from the bicycle. Thus, the conventional electric bicycle may further include a battery housing or a battery carrier. This battery carrier is then, in turn, mounted in a battery case that is fixed in some way to the vehicle so that, upon insertion, it can be electrically connected to the electric motor and its control. The battery carrier 1 646252/3 should be easy to insert and remove from the battery case for charging and replacement.

Because of the fact that the battery can be easily removed and returned for charging purposes, there is some risk of battery theft. Therefore, it is desirable to provide a lock for locking the battery carrier in the battery box when installed in the vehicle so as to prevent theft.

Such an issue is addressed for example in US 6,095,270.

US 6,095,270 discloses a battery carrier, battery box and locking assembly for an electric power assisted vehicle, such as a bicycle. The battery box includes a base portion having a cup shape and which is adapted to detachably receive the battery carrier.
