Battery: Description and Operation

Battery and Cables









OVERVIEW
The battery is mounted in a protective box, located in the engine compartment, on the passenger side. It sits in a tray and is secured with clamp plates and bolts.
The battery terminal posts allow for the battery cables to be connected with clamp type connections.
The battery positive terminal is fitted with a mega fuse, which is a 400 Amp device housed in a black fuse carrier, integral to the battery clamp. Power feed to the BJB (battery junction box) is taken from a tap on the battery clamp before the mega fuse.
In the event of a crash the mega fuse is designed to blow, this isolates the power from the generator and starter motor, but allows power to be delivered, via the CJB (central junction box), to the rest of the vehicle.
There are two different battery sizes:
- H7 - All petrol variants
- H8 - All diesel variants
The battery has a vent pipe to allow for thermal expansion and to vent oxygen and hydrogen gases, which are produced under certain charging conditions.
When removing the battery, ensure the alarm is disarmed and the ignition is switched off. Always disconnect the negative terminal first and then the positive. When refitting the battery, always fit the positive terminal first followed by the negative.
If the battery requires recharging, always use an approved constant current charger, designed for lead-calcium batteries. DO NOT use a fast charger, as permanent damage to the battery may occur.

Delivery Mode
The vehicle is fitted with a transit relay which must be removed before delivery of the vehicle to the customer. This is a disposable device and NOT for use by the customer. This relay fits in series with the battery and ground; it disconnects the battery from the vehicle's ground and thus eliminates quiescent current during delivery. The relay must be removed before delivery to the customer. The connector to the relay has a permanent live feed and therefore must be stowed on the given stowage point.

Battery Monitoring System





Optimal battery health is a fundamental factor in the correct operation of the Stop/Start system, therefore to calculate and communicate the battery status a Battery Monitoring System (BMS) module is introduced.
