Advanced battery used in prototype truck
Advanced Lead Acid Gel battery that has a thermal management system to keep the power pack at its optimum operating temperature is being used in a prototype delivery vehicle.
CMP Batteries of Bolton has provided the battery for the Electric Mercury prototype Specialist Delivery Vehicle (SDV) Orders for vehicles have already been placed by Arla Foods (Express Dairies) and Sheffield City Council and will be delivered in 2006

Reaching new heights in the charger room
Chloride Motive Power has launched an exciting new breakthrough in charger room systems.
The E-Mercury vehicle will be available from the new trading company Modec ? after their purchase from London Taxis International.
E-Mercury has been designed specifically for urban and inner city use and the makers believe E-Mercury will be the delivery vehicle of the future.
The SDV (commonly referred to as 'milk floats') with the Chloride Motive Power battery option incorporated has a governed top speed of 50mph and a potential range of over 65 miles.

Battery charger is smaller and lighter
Single phase high frequency battery charger suits classic 'flooded', low maintenance and gel maintenance free batteries, is a fraction of the size of an equivalent conventional charger.
The vehicle has a versatile 2 tonne payload capacity and a gross vehicle weight, including battery of 5.5 tonnes.
Chloride Motive Power's Advanced Lead Acid Gel battery incorporates a thermal management system to keep the power pack at its optimum operating temperature.
In summer it keeps the battery cool and on cold winter mornings it will keep the battery warm to ensure maximum battery performance.
It achieves this by means of a sensor that monitors the ambient temperature and then either pumps air-cooled water round it or uses heat from the heat exchanger if it needs to be kept warm.
Today's electric delivery vehicles demand such performance because they now have to travel further and are often required to be working all day.
If required, batteries can be replaced using a fast battery exchange system that will be available at its depot or one of a number of special exchange points that will be developed as part of the operating infrastructure.
The battery powers a sophisticated AC drive system with permanent magnet motor from Azure Dynamics to produce 57Kw 207Nm at 6000 rev/min.
Other power options will be available, including a diesel electric hybrid, but Modec believes that the battery version will be particularly popular due to its low running costs, cheap maintenance costs and zero road tax because it is environmentally friendly.
A sophisticated electronic system can set the vehicles management system to a particular driver's profile.
If, for example, one duty cycle involves multiple stop-start deliveries over a limited area, then the maximum speed of the vehicle can be restricted to 30mph, which ensures that the draw on the battery is minimised.
However, if just a small number of drops are required, but over a longer distance or larger area, the maximum of 50mph can be made available, thus ensuring complete flexibility to the user.
