Electric vehicle roadworthy requirement
An electric vehicle that has been scratch built or converted in New Zealand after 1 January 1992, should be certified from the low volume vehicle code. They consider that the vehicle should be designed and constructed with those material which is fit for the purpose and must be safe. Any work which is associated on the vehicle should be done tidy and tradesman skill manner like fabrication work, electrical work and other.

the general electric system requirement in the electric vehicle is the system provide a safety if there is any fail occurred in the system. The system should have the fail measures such as circuit breakers or fuses which offer suitable protection in case of a short circuit.

Wires should not be connected to the vehicle chassis or body and used proper sealed component which prevent it from any contamination. High voltage wires should not be positioned with in the body pillars, roof or any outer sills and must not incorporate sharp bends. The electrical wiring within an electric vehicle which carries high voltage or current should be orange color, the conduct must be orange color.
The electrical vehicle should have over-current protection system which are mounted closely to both the poles of the power source. The system must be able to protect electric wiring and components if overload capacity between 20%-40%. External charging circuits
The charging system of an electric vehicle which has an external power source that should be installed an interlock which immobilises when the charging cable is connected. The external power source must be installed with appropriate charger specification cable and plugs. If the external power source is 230-volt domestic power, it should be installed by the certificate of compliance which is provided by the registered electrician because they confirm that the wiring is up to

The compartment where the batteries is hold is able to withstand 20 times the weight of the batteries in the forward longitudinal direction. If the batteries located in the forward of the passenger compartment, the battery structure is able to withstand 2.5 times from the weight of batteries. Fig: 2 Batteries compartment and ventilation system
Battery venting and compartments
If the batteries have potential to emit gas or hazardous liquid, it should be effectively ventilated and sealed which prevent any hazard. Batteries must be placed outside from the passenger compartment and the compartment should be made from non-porous material. The compartment material must be resist the corrosion any hazard gas or liquid leakage. The battery venting must open to the atmosphere from which all the gases are driven out and there should be no spark resource which exhaust the batteries gas. If the batteries emit large amount of gas in normal function than it should be required a forced ventilation system. The system must be function automatically whenever the huge amount of gas emits and it must operate after any operation complete. If the vehicle has a forced ventilation Colling system for the batteries it must work automatically and has a sufficient air flow for maintaining the temperature. The inlet and outlet of the ventilation should
