A charging circuit recharges the boost battery from the main battery during operation of the motor.

The charging circuit also maintains a charge balance between the boost battery and the main battery when the two batteries have different chemistries.

This alternating current, after rectification, was used to charge the back-up battery.

An auxiliary boost battery assists the main battery in supplying a high-level current at a higher discharge rate thereby causing the motor to operate in a high-performance drive mode.

In one embodiment, participation of the boost battery in powering the electric motor can be controlled automatically according to sensed changes in the load.

A charging circuit recharges the boost battery from the main battery during operation of the motor.

Battery electrode separator envelope (10) having reinforcement material in selected areas and method of reinforcement material application.

The reinforcing divider defines a plurality of thermal transfer elements externalized of the battery case.

The charging circuit also maintains a charge balance between the boost battery and the main battery when the two batteries have different chemistries.

A shock dampening material can be provided between the reinforcing divider and the battery case to facilitate a mechanical, shock-dampened, reinforcing integration of the divider and case.
